RP153 Series
Low Voltage Dual 150mA Voltage Regulator (LDO Regulator) with 2 input pins

Product Specifications

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.

  • xxx … Specify the combination of set output voltage (VSET) within the range of 0.8 V to 3.6 V in 0.1 V step.
  • # … Specify the auto-discharge option and the improved transient response option.
    A: Auto-discharge function not included
    B: Auto-discharge function included
    D: Transient response improved, Auto-discharge function not included
    E: Transient response improved, Auto-discharge function included

* 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.
