RP101_17 Datasheet, PDF (1/33 Pages) RICOH electronics devices division – Supply Current Typ. 18uA
RP101x SERIES
0.6% ACCURACY LOW NOISE 300mA LDO REGULATOR
NO.EA-167-160425
OUTLINE
The RP101x 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 RP101x 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
DFN(PLP)1612-4 (t0.6mm type) or DFN(PLP)1612-4B (t0.4mm type), therefore high density mounting of the
ICs on boards is possible.
