RP202 Series
Automatic ECO Mode Shift Low Voltage 200mA LDO Regulator

Download Datasheet

  • Description

    The RP202 Series are CMOS-based auto ECO mode switching LDO regulators featuring 200mA output. In auto switching mode, the operation can switch automatically to fast response mode or low power mode of the ECO function according to output current. (Automatic switching to fast response mode under IOUT > 8mA conditions or to low power mode under IOUT < 1mA conditions.)

    In low power mode, supply current is as low as 2.5µA. In fast response mode, ripple rejection is 70dB and noise is low. RP202 requires neither ECO pin for switching mode nor microcontroller pin. RP202 supports low voltage, featuring input voltage from 1.4V and output voltage from 0.8V. Standby mode and auto-discharge function are also available. In addition to SOT-23-5 and SC-88A packages, and a 1mm square DFN(PL)1010-4 are also available.
