The RP201x series are CMOS-based manual/automatic mode shift LDO regulators featuring 150mA 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 1.5μA. In fast response mode, ripple rejection is 70dB and noise is low. By inputting control signal into the AE pin, the mode of the regulator can be fixed with fast response mode. In addition to a 0.69mm square WLCSP-4-P5 package and a 1.2mm square DFN(PLP)1212-6 are also available.
The Ricoh RP201x Series are CMOS-based manual/automatic mode shift Low Dropout (LDO) regulators featuring a 150mA output. These regulators are designed for applications requiring both fast response and low power consumption, such as mobile phones, cameras, and VCRs. They feature an ECO function that allows automatic switching between fast response mode and low power mode based on the output current, or manual fixing of the mode via the AE pin.

The ECO function allows the regulator to switch automatically between fast response mode and low power mode depending on the system load.
The mode can be fixed to fast response mode by inputting a control signal into the AE pin.
The available packages are WLCSP-4-P5 and DFN(PLP)1212-6.
