The RP202x Series is a CMOS-based auto mode switching LDO regulator with a 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. RP202x requires neither ECO pin for switching mode nor microcontroller pin. RP202x 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(PLP)1010-4 are also available. RP202x Series contributes to the downsizing of the hand-held equipment because it can use the 0.47μF ceramic capacitor.
The Ricoh RP202x Series are CMOS-based automatic mode switching LDO regulators featuring a 200mA output. They automatically switch between fast response mode and low power mode based on output current, eliminating the need for an external ECO pin or microcontroller control. The series supports low input voltages starting from 1.4V and output voltages from 0.8V.
| Output Current | 200mA |

The regulator automatically switches to fast response mode when output current is greater than 8mA, and to low power mode when it is less than 1mA.
No, the RP202x Series requires neither an ECO pin for switching mode nor a microcontroller pin.
A ceramic capacitor of 0.47uF or more can be used.
