150mA LDO REGULATOR
RP104 SERIES
OUTLINE
Preliminary
NO. EA-150-070402
The RP104 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 ultra low supply current (Typ.1µA) and a chip enable function prolongs the battery life.
Since the packages for these ICs are PLP1010-4, SOT-23-5 and SC-82AB, therefore high density mounting of
the ICs on boards is possible.
