RP104x SERIES
150mA ULTRA LOW SUPPLY CURRENT LDO REGULATOR
NO.EA-150-080530
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, therefore high density
mounting of the ICs on boards is possible.

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 (DFN(PLP)1010-4)

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum ratings are threshold limit values that must not be exceeded ever for an instant under
any conditions. Moreover, such values for any two items must not be reached simultaneously. Operation
above these absolute maximum ratings may cause degradation or permanent damage to the device.
These are stress ratings only and do not necessarily imply functional operation below these limits.
