RP103x SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-149-071015
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
DFN(PLP)1010-4, 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,

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 (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.
