R1131x Series

Low Voltage 300mA LDO

The R1131x Series are CMOS-based LDO regulators featuring 300mA output. The input voltage (VIN) is as low as Min. 1.4V and the

output voltage can be set from 0.8V. The CE pin can switch the regulator into standby mode. Ceramic capacitors can be used.

(V^OUT1.0V)
