The RP153 Series are CMOS-based dual output LDO regulators featuring 150mA output with 2 input pins. RP153 features a supply current as low as 40µA per output, a minimum input voltage from 1.4V and the output voltage can be set from 0.8V to 3.6V (in 0.1V steps). Due to the low minimum input voltage. RP153 is able to extend battery life, additionally the LDO has less power dissipation by the low dropout voltage between input and output. The enhanced load transient response version is available. RP153 is available in DFN1216-8 package.

RP153L (VR1/VR2) Dropout Voltage vs. Output Current
*) The tab is substrate level (GND).
**) The GND pin must be wired together when it is mounted on board.
The set output voltage, the auto discharge function and the improved transient response are user-selectable options.

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