RP130x SERIES
LOW NOISE 150mA LDO REGULATOR
NO.EA-173-131031
OUTLINE
The RP130x Series are CMOS-based positive voltage regulator ICs with high ripple rejection, low dropout
voltage, high output voltage accuracy and extremely low supply current. Each of these ICs consists of a voltage
reference unit, an error amplifier, a resistor-net for voltage setting, a short current limit circuit and a chip enable
circuit.
These ICs have an excellent low supply current performed by CMOS process, moreover they perform with low
dropout voltage due to built-in low ON-resistance. A chip enable function prolongs the battery life.
The input transient response, the load transient response and the ripple rejection have been improved in the
RP130x Series compared with the conventional products. Besides achieving low supply current (Typ.38μA).
The range of the operation voltage is capable from 1.7V to 6.5V and the range of the output voltage is capable
from 1.2V to 5.3V for this product, which is wider range as our conventional product R1114x series.
The output voltage of these ICs is fixed with high accuracy. 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.
