GM2950/GM2951
100mA, LOW DROPOUT
VOLTAGE REGULATORS
Description
Features
The GM2950 and GM2951 is a low power voltage
regulator. This device is an excellent choice for use
in battery powered application such as cordless
telephone, radio control systems, and portable
computers.
High accuracy output voltage
Guaranteed 100mA output
Very low quiescent current
Low dropout voltage
The GM2950/GM2951 features very low quiescent
current (75µA Typ.) and very low drop output
voltage (Typ. 40mV at light load and 380mV at
100mA). This includes a tight initial tolerance of
0.5% typ., extremely good load and line regulation
of 0.05% typ., and very low output temperature
coefficient, making the GM2950/ GM2951 useful as
a low power voltage reference.
Extremely tight load and line
regulation
Very low temperature coefficient
Needs only 1μF capacitor for stability
Error flag warns of output dropout
Logic-controlled electronic shutdown
The GM2951 is available in 8-pin plastic packages.
The regulator output voltage may be pin-strapped
for a -XX volt or programmed from 1.24 volt to 29
volts with external pair of resistors.
Output programmable from 1.24V to
29V
The GM2950 is offered in 3-pin TO-92 package
compatible with other fixed regulator.
