âRP103Qxx2 (SC-88A) is the discontinued product. As of April in 2016
RP103x SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-149-160426
OUTLINE
The RP103x 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 RP103x 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
DFN(PLP)1010-4, SC-82AB, SC-88A, SOT-23-5, therefore high density mounting of the ICs on boards is
possible.
