R1124N SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-095-0512
OUTLINE
The R1124N 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 R1124N 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 package for these ICs is SOT-23-5, high
density mounting of the ICs on boards is possible.

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: When the additional ceramic capacitors are connected 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 1.0µF 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

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:
CE
VOUT
Ceramic
Cap.
R1124Nxx1B

Measuring Circuit for white noise; R1124Nxx1B
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
components as ones to be used on the PCB.)
