R1114x S ERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-094-0512
OUTLINE
1
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.
