RP104x SERIES
150mA ULTRA LOW SUPPLY CURRENT LDO REGULATOR
NO.EA-150-070727
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 PLP1010-4, SOT-23-5 and SC-82AB, therefore high density mounting of
the ICs on boards is possible.

Setting Output Voltage (V
OUT
):
The following 16 kinds of voltage are standard.
1.2V, 1.3V, 1.5V, 1.8V, 1.85V, 1.9V, 2.0V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V, 3.0V,
3.2V, 3.3V
Exceptions:1.85V=RP104x181x5-xx-x, 2.85V=RP104x281x5-xx-x
Designation of Mask Option
B: active high, without auto discharge function* at OFF state.
C: without chip enable circuit.
D: active high, with auto discharge function* at OFF state.
Designation of Taping Type:
Ex. TR (refer to Taping Specifications; TR type is the standard direction.)
Designation of composition of pin plating:
-F: Lead free plating (SOT-23-5, SC-82AB)
None: Au plating (PLP1010-4)
