RP100x SERIES
0.6% ACCURACY LOW NOISE 200mA LDO REGULATOR
NO.EA-140-160425
OUTLINE
The RP100x 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 RP100x 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, therefore high density mounting of the ICs on boards is possible.
