100mA Low Dropout Voltage Regulator

LM2931

Description

Features

•

Guaranteed 100mA Output

The Bay Linear LM2931 are low power voltage regulators

designed for a wide range of applications. They are an

excellent choice for use in Battery Powered applications. The

LM2931 feature low quiescent current (100 µA Typ.) and low

dropout of only 60mV at light loads and 300mV (typ.) at

100mA. The LM2931 has tight initial tolerance of 0.5% typ.,

extremely good load and line regulation of 0.05% typ. and very

low output temperature coefficient.

Fixed Versions 3.3V, 50.V, 8.0

Very Low Quiescent Current

Low Dropout Voltage

Regulation

•

Very Low Temperature Coefficient

Current and Thermal Limiting

Reverse Battery Protection of –20V

Transient protection of 60V

The Bay Linear LM2931 is available as a fixed voltage

regulator and as an adjustable regulator in TO-92 and 8SOIC

packages. The Bay Linear LM2931 in an 8SOIC package has

an adjustable output voltage from 3V to 24V, programmed

with a pair of external resistor. The logic compatible shutdown

enables the regulator to be switched ON and OFF.

Output programmable from 3V to 24V
