R1114x SERIES
LOW NOISE 150mA LDO REGULATOR

OUTLINE
The R1114x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply
current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an
error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The line transient response and load
transient response of the R1114x Series are excellent, thus these ICs are very suitable for the power supply for
hand-held communi cation equipment.
The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are SOT-23-5,
SC-82AB, and SON1612-6 therefore high den sity mounting of the ICs on boards is possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system u sing the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment sho uld b e 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 su rge. And the semicondu ctor devices may receive seriou s damage whe n they continue
to operate over the recommended operating conditions.

TECHNICAL NOTES
When using these ICs, consider the following p oints:
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 capacit or C OUT with good frequency characteristics and ESR (Equivalent Series Resistance).
(Note: If additional ceramic capa citors are connected with parallel to the output pin with an output capacitor for
phase compensation, the operation might be unstable. Because of this, test these ICs with as same external
component s as ones to be used on the PCB.)
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor with a capacitance value as much as 1.0μF or more between VDD and GND pin, and as
close as possible to the pins.
Set external components, especially the output capacitor, as close as possible to the ICs, and make wiring as
short as possible.

ESR vs. Output Current
When using these ICs, consider the following p oints:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, use a capacitor C OUT with good frequency characteristics and ESR (Equivalent Series Resistance)
of which is in the range described a s follows:

Measuring Circuit for white noise; R1114xxx1B/D
The relations between IOUT (Output Current) and ESR of an output capacitor are shown below. The conditions
when the white noise level is under 40μV (Avg.) are marked as the hatched area in the graph.
(Note: If additional ceramic capacitors are connected to the Output Pin with Output capacitor for phase
compensation, the operation might be unstable. Because of this, test these ICs with as same external
component s as ones to be used on the PCB.)
