LOW NOISE 150mA LDO REGULATOR
R1114X SERIES
g
OUTLINE
The R1114X Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely 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
communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are SOT-23-5 and SC82-AB,
therefore high density mounting of the ICs on boards is possible.

n TECHNICAL NOTES
When using these ICs, consider 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 capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance).
(Note: If additional ceramic capacitors 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 components 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 1.0mF 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.

n TECHNICAL NOTES
When using these ICs, consider the following points:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this purpose, use
a capacitor COUT with good frequency characteristics and ESR (Equivalent Series Resistance) of which is in the range
described as follows:

IOUT
Measuring Circuit for white noise; R11X4XXX1B/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 40mV(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 components as ones to be used on the PCB.)

(3) Temperature: -40°C to 25°C
