R1131D281A Datasheet LDO REGULATOR

Manufacturer: RICOH

Overview: R1131x SERIES Low Voltage 300mA LDO REGULATOR NO.EA-116-061102 OUTLINE The R1131x Series are CMOS-based low voltage regulator ICs with output voltage range from 0.8V to 3.3V. The minimum operating voltage is 1.4V. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, a current limit circuit, and a chip enable circuit. www.DataSheet4U.com To prevent the destruction by over current, current limit circuit is included. Standby mode realizes ultra small consumption current. The output voltage of these ICs is internally fixed with high accuracy. Since the packages for these ICs are SOT-23-5, SON-6, and HSON-6, high density mounting of the ICs on boards is possible.
