RC2951

Adjustable Micropower Voltage Regulator

Features

Description

• High accuracy output voltage

The RC2951 is a voltage regulator speciﬁcally designed to

maintain proper regulation with a very low dropout voltage

(Typ. 40mV at light loads and 380 mV at 100mA). It has a

low quiescent bias current of 75µA and is capable of supply-

ing output currents in excess of 100mA. It has internal cur-

rent and thermal limiting protection. The output can be

programmed from 1.24V to 29V with two external resistors.

A ﬁxed output voltage (3.3V) is also available.

• Guaranteed 100 mA output current

• Extremely low quiescent current

• Extremely tight load and line regulation

• Requires only a 1.0µF output capacitor for stability

• Internal Current and Thermal Limiting

• Error ﬂag warns of output dropout

• Logic-controlled electronic shutdown

• Output programmable from 1.24 to 29V

• Fixed 3.3V version available

The error ﬂag output can be used as power-on reset for

warning of a low output voltage. The Shutdown input feature

allows a logic level signal to turn on and off the regulator

output. The RC2951 is ideally suited for battery powered

computer, consumer, and industrial equipment where an

extension of useful battery life is desirable. The RC2951 is

available in an 8-pin SOIC package.

• -25°C to +85°C operating range

• 8 lead SOIC package
