RP130x-Y Series
Low Noise 150mA LDO Regulator for Industrial Applications
NO.EA-336-190401
OUTLINE
The RP130x is a CMOS-based positive voltage regulator IC with high ripple rejection, low dropout voltage, high
output voltage accuracy and extremely low supply current. The RP130x consists of a voltage reference unit, an
error amplifier, a resistor network for voltage setting, a short current limit circuit, and a chip enable circuit.
The RP130x has low supply current characteristics in the CMOS process. In addition, the RP130x can supply
a low dropout voltage, which becomes the smallest difference between the input voltage and output voltage by
having a low on-resistance and also can achieve the battery's long life by a chip enable function.
When compared with the conventional products of high-speed type, the RP130x achieves low consumption
current of 38A (Typ.) while improving the input transient response, the load transient response, and the ripple
rejection.
The RP130x supports two package types: DFN(PLP)1010-4 and SOT-23-5. By the adoption of the ultra-
compact DFN(PLP)1010-4, the RP130x can achieve a higher density mounting than ever.
This is a high-reliability semiconductor device for industrial applications (-Y) that has passed both the screening
at high temperature and the reliability test with extended hours.

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.
