RP200x Series
Automatic Mode Shift 300mA LDO
The RP200x Series are CMOS-based 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 lower power mode, supply current is as low as 1μA. 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 and SC-88A packages, a 0.69mm square WLCSP-4-P5 package and a 1.2mm square DFN(PLP)1212-6 are also
available.
