RP200x Series
Manual/Automatic Mode Shift Low Voltage 300mA LDO
The RP200x Series are CMOS-based manual/automatic mode shift LDO regulators featuring 300mA 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 SOT-23-5 package, a 0.69mm
square WLCSP-4-P5 package and a 1.2mm square DFN(PLP)1212-6 are also available.
