RP201 Series
Manual/Automatic ECO Mode Shift Low Voltage 150mA LDO Regulator
-
Description
The RP201 Series are CMOS-based manual/automatic ECO mode shift LDO regulators featuring 150 mA 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 > 8 mA conditions or to low power mode under IOUT < 1 mA conditions.)
In low power mode, supply current is as low as 1.5 µA. 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.
