Tantalum capacitors also are not prone to dry-out. The electrolyte used in electrolytic capacitors tends to dry out with time, degrading the performance. Avoid using extremely low ESR film or ceramic capacitors to avoid instability problems. See Figure 9, `ESR stability versus output current'. TECHNICAL DESCRIPTION The SA57001 is a family of series regulators incorporating a bandgap reference, two feedback amplifiers, a thermal shutdown circuit, and an output current limiting circuit. Both feedback amplifiers are referenced to the bandgap reference. See the device diagram shown in Figure 22. Keep in mind that the output capacitor tries to supply any instantaneous increase in load current from its stored energy. Using higher values of capacitance will enhance transient load performance as well as stability. Lowering the ESR of the capacitors will also improve the transient response to load current changes, but it will decrease stability. A PNP transistor in the device's output serves as the series pass element. The output PNP pass transistor incorporates a dual collector. The first feedback amplifier monitors the first collector's output voltage through the use of a voltage divider network fed directly from the output. The second collector produces a small current that is proportional to the output current. The proportional current flows through a resistor, generating a second feedback voltage that is proportional to the output current. This voltage is fed to the second feedback amplifier to limit the output current to a safe operating level. Noise reduction The noise reduction pin of the device is connected to the internal reference voltage node. Bypassing this pin to ground with a capacitor (0.01 F typical) will reduce the output voltage noise for demanding applications. This also improves the AC performance by increasing ripple rejection. Both feedback amplifiers act on the same control node, to control the PNP pass transistor's conduction. This dual path output monitoring maintains a constant output voltage while also limiting the output current. In addition, bypassing the input pin to ground with a capacitor (0.1 F typical) will suppress input ripple form the power source. Thermal overload protection Stability factors: Capacitance and ESR When the junction temperature reaches approximately 150 C, the thermal sensor signals the shutdown logic to turn off the pass transistor. After the junction temperature has cooled to below the thermal threshold, plus the hysteresis, the sensor signals the shutdown logic to turn the pass transistor on again. This will create a pulsed output during lengthy thermal overloads. The operating stability of linear regulators is determined by start-up delay, transient response to load currents, and stability of the feedback loop. The SA57001 has a fast transient loop response, with no built-in delay. Capacitors play an important part in compensating the regulator's output. A 4.7 F aluminum electrolytic capacitor is recommended for most applications, because they provide good performance with minimal cost. A tantalum capacitor can also be used. Tantalum VIN SA57001-XX NOTE: Thermal overload protection is to protect the device during fault conditions. Do not exceed the maximum junction-temperature rating of Tj = +150 C during continuous operation. 5 4 THERMAL SHUTDOWN NOISE 3 ON/OFF 1 300 k 400 k GND 2 SL01419 Figure 22. Functional diagram. 2001 Aug 01 9 VOUT Philips Semiconductors Product data Microminiature, low power consumption, low dropout regulator APPLICATION INFORMATION SA57001-XX Heat dissipation factors Heat generated within the device is removed to the surrounding environment by radiation or conduction along several paths. In general, radiated heat is dissipated directly into the surrounding ambient from the chip package and leads. Conducted heat flows through an intermediate material, such as the leads or thermal grease, to circuit board traces and heat sinks in direct contact with the device's package or leads. The circuit board then radiates this heat to the ambient. For this reason, adequate airflow over the device and the circuit board is important. Power dissipation factors The thermal performance of linear regulators depends on the following parameters: Maximum junction temperature (Tj) in C Maximum ambient temperature (Tamb) in C Power dissipation capability of the package in Watts (PD) Junction-to-ambient thermal resistance in C/W The Maximum Junction Temperature and Maximum Power Dissipation are both determined by the manufacturer's process and device's design. For the most part the ambient temperature is under the control of the user. The Maximum Ambient Temperature depends on the process used by the manufacturer. The package type and manufacturer's process determines Junction-to-Ambient Thermal Resistance. The SOT23-5 package is too small to easily use external heat sinks to increase the surface area and enhance the dissipation of generated heat. Heat dissipation must depend primarily on radiated heat into the surrounding environment and the heat flow through the leads into the printed circuit board. Some improvement can be realized by allowing additional exposed copper on the circuit board near the device to serve as heat absorbers and dissipaters for the device. These parameters are related to each other as shown in the following equation: The overall thermal resistance from junction to the surrounding ambient of the package (Rth(j-a)) is made up of three series elements and can be thought of as the total resistance of a series electrical circuit. These elements are: Tj = Tamb + ( PD x Rth(j-a) ) The term ( PD x Rth(j-a) ) represents the temperature rise from the ambient to the internal junction of the device. Rth(j-c) = Thermal resistance from Junction-to-Case Rth(c-s) = Thermal resistance from Case-to-heat Sink Rth(s-a) = Thermal resistance from heat Sink-to-Ambient Power dissipation calculations A regulator's maximum power dissipation can be determined by using the following equation: Rth(j-a) is based primarily on the package type and the size of the silicon chip used in the device. The composition of package materials plays an important part. High heat conductivity materials produce reduced Junction-to-Case resistances. PD(max) = VIN(max)IG + [VIN(max) - VOUT(min)] IOUT(max) where: VIN(max) is the maximum input voltage IG is the maximum Ground Current at maximum output current VOUT(min) is the minimum output voltage IOUT(max) is the maximum output current Rth(c-s) value is based on the package type, heat sink interface, and contact area of the device to the heat sink. The use of thermal grease or an insulator will increase the transfer of heat from the case to the heat sink. (VIN(max)IG) represents heat generated in the device due to internal circuit biasing, leakage, etc. [VIN(max) - VOUT(min)] is the input-to-output voltage drop across the device due to the IOUT(max) current. When multiplied by IOUT(max), this represents heat generated in the device due to the output load current. Heat generated by the device represents lost energy (an inefficiency). Rth(s-a), which is thermal resistance from heat sink to the ambient, is based on heat sink emissivity and airflow over the heat sink to carry the heat away. The heat sink to ambient heat flow is dependent on the ability of the surrounding ambient media to absorb the heat. The total Rth(j-a) thermal resistance is expressed as: The SA57001 device should not be operated under conditions that would cause a junction temperature of 150 C to be generated because the thermal shutdown protection circuit will shut down the device at or near this temperature. Rth(j-a) = Rth(j-c) + Rth(c-s) + Rth(s-a) The maximum power that a given package can handle is given by: PD + 2001 Aug 01 10 T j(max) * T amb R th(j*a) Philips Semiconductors Product data Microminiature, low power consumption, low dropout regulator SA57001-XX DEFINITIONS Output noise is the integrated output noise voltage specified over a frequency range and expressed in nV/kHz or Vrms. It is measured with the input voltage and output load current held constant during test. Line regulation is the change in output voltage caused by a change in input line voltage. This parameter is measured using pulse measurement techniques or under conditions of low power dissipation so as to not significantly upset the thermal dynamics of the device during test. Current limiting is internal device circuitry incorporated to limit the output current of the device. This feature is incorporated in the device to protect the device against output over current conditions or output shorts to ground. Load regulation is the change in output voltage caused by a change in output load current and is measured in a manner which will not cause significant heating of the device during test. Thermal shutdown is internal device circuitry incorporated in the device to shut down the device when the chip temperature reaches a specified temperature. This feature protects the device from excessive operating temperatures that would otherwise be catastrophic to the device. Over heating can be created by accidental output shorts. Quiescent current is that current which flows to the ground pin of the device when the device is operated with no output current flowing. Ground current is that current which flows to the ground pin of the device when the device is operated with output current flowing due to an applied load. It is the measurement difference of input current minus the output current. Dropout voltage is the input/output differential voltage at which the regulator ceases to maintain specified output regulation if the input voltage is reduced. It is highly influenced by device junction temperature and load current.
