RP130x Series
Low Noise 150 mA LDO Regulator
No. EA-173-181227
OUTLINE
The RP130x is a voltage regulator IC with high ripple rejection, low dropout voltage, high output voltage
accuracy and extremely low supply current. The IC 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.
This IC has 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 compared with the conventional products. Besides achieving low supply current (Typ.38 μA).
The range of the operation voltage is capable from 1.7 V to 6.5 V and the range of the output voltage is capable
from 1.2 V to 5.3 V for this product, which is wider range as our conventional product R1114x.
The output voltage of this IC is fixed with high accuracy. Since the packages for this IC are DFN(PLP)1010-4,
SOT-23-5 and SC-82AB, therefore high density mounting of the IC on board is possible.

Auto-discharge function quickly lowers the output voltage to 0 V by releasing the electrical charge in the external
capacitor when the chip enable signal is switched from the active mode to the standby mode.

RECOMMENDED OPERATING CONDITIONS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended operating
conditions.
