R1114x SERIES

LOW NOISE 150mA LDO REGULATOR

NO.EA-094-111026

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 communication 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 density mounting of the ICs on boards is possible.
