RP104x SERIES
150mA ULTRA LOW SUPPLY CURRENT LDO REGULATOR
NO.EA-150-131016
OUTLINE
The RP104x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current and low ON-resistance. 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.1.0µA), which prolong the battery life.
Since the packages for these ICs are DFN(PLP)1010-4, SOT-23-5 and SC-82AB (Non-promotion), therefore
high density mounting of the ICs on boards is possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
