RP173x SERIES 11V Input 150mA LDO NO.EA-256-111020 OUTLINE The RP173x Series are CMOS-based voltage regulator ICs featuring 150 mA output and low supply current of Typ.2.0A. Each of these ICs consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, a current limit circuit, a chip enable circuit and a Reverse Current Protection Circuit. RP173x Series are suitable for the power source such as the equipment being in the standby-mode. A version with /CE input pin has reduced CE pull-up resistance to make its supply current ultra low. The RP173x Series have Max.11V Input voltage and are applicable to the portable communication equipment that require the 2-cell Li-ion battery. Also they are applicable to the non-portable communication equipments. As this series includes Reverse Current Protection Circuit, there is little leakage current, if it's used as back-up circuit. Since the packages for these ICs are the SOT-23-5 package, SC-88A, or DFN(PLP)1010-4 of 1mm square, high density mounting of the ICs on boards is possible.

RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 7 RP173x TYPICAL APPLICATIONS VDD C1 RP173x Series CE VOUT VOUT C2 GND External Parts Example: C2: Ceramic Capacitor 0.1F, Murata,GRM155B31C104KA87D TECHNICAL NOTES When using the ICs, please note the following points. Phase Compensation In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use a 0.1F or more capacitor C2. In case of using a tantalum capacitor, the output may be unstable due to inappropriate ESR. Therefore, the full range of operating conditions for the capacitor in the application should be considered. PCB Layout Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor C1 with a capacitance value as much as 0.1F or more between VDD and GND pin, and as close as possible to the pins. Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring as short as possible. POWER ACTIVATION If the ICs are started up with VIN and VCE under the no-load condition, the both pin voltages have to be started up with faster than 2.0V/s. If the IC is started up with slower than 2.0V/s under the no-load condition, start up the IC only with VCE. 8 RP173x REVERSE CURRENT PROTECTION CIRCUIT The RP173 Series include a Reverse Current Protection Circuit, which stops the reverse current from VOUT pin to VDD pin or to GND pin when VOUT becomes higher than VIN. Usually, the LDO using Pch output transistor contains a parasitic diode between VDD pin and VOUT pin. Therefore, if VOUT is higher than VIN, the parasitic diode becomes forward direction. As a result, the current flows from VOUT pin to VDD pin. The ICs of this series switches the mode to the reverse current protection mode before VIN becomes lower than VOUT by connecting the parasitic diode of Pch output transistor to the backward direction, and connecting the gate to VOUT pin. As a result, the Pch output transistor is turned off and the all the current pathways from VOUT pin to GND pin are shut down to maintain the reverse current lower than [IREV] of the Electrical Characteristics. Switching to either the normal mode or to the reverse current protection mode is determined by the magnitude of VIN voltage and VOUT voltage. For the stable operation, offset and hysteresis are set as the threshold. The detection/ release thresholds of both normal and reverse current protection modes are specified by [VREV_DET] and [VREV_REL] of the Electrical Characteristics. Therefore, the minimum dropout voltage under the small load current condition is restricted by the value of [VREV_REL]. Fig.1 and Fig.2 show the diagrams of each mode, and Fig.3 shows the load characteristics of each mode. When giving the VOUT pin a constant-voltage and decreasing the VIN voltage, the dropout voltage will become lower than the [VREV_DET]. As a result, the reverse current protection starts to function to stop the load current. By increasing the dropout voltage higher than the [VREV_REL], the protection mode will be released to let the load current to flow. If the dropout voltage to be used is lower than [VREV_REL], the detection and the release may be repeated. The operation coverage of the Reverse Current Protection Circuit is VOUT 1.5V. However, under the condition of VIN=0V, always the reverse current protection mode is operating.
