RP103x SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-149-070720
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 PLP1010-4,
SOT23-5, SC82-AB, 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, 2.3V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V,
3.0V, 3.1V, 3.3V
Exceptions:1.85V=RP103x181x5-xx-x, 2.85V=RP103x281x5-xx-x
Designation of Mask Option
B: active high, without auto discharge function* at OFF state.
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)
