RC2951 - Adjustable Micropower Voltage Regulator

General Description

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 supplying output currents in excess of 100mA.

Key Features

  • High accuracy output voltage 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 -25°C to +85°C op.
