RP201x Series  
Automatic Mode Shift 150mA LDO  
The RP201x Series are CMOS-based 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 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.

• Input Voltage Range (VIN)···········1.4V to 5.25V  
• Fold-back Protection Circuit ···········Current limit Typ. 50mA  
• Auto-Discharge function ·················D Version  
• Packages········································WLCSP-4-P5, DFN(PLP)1212-6,  
SC-88A, SOT-23-5  
• Output Voltage Range (VOUT)······0.8V to 4.0V (internally fixed)  
• Output Voltage Accuracy ············± 1%  
• Ceramic capacitor can be used. ·····1μF or more
