GL2950/ GL2951
100mA LOW DROPOUT VOLTAGE REGULATOR
Description
The GL2950 and GL2951 are low power voltage regulato-
rs. These device excellent choice for use in battery power-
ed application such as cordless telephone, radio control sy-
stems, and portable computers.
The GL2950/GL2951 features very low quiescent current
(75uA 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 GL2950/ GL2951 useful as a low-
power voltage reference.
The error flag output feature is used as power-on reset for
warn of a low output voltage, due to following batteries on
input. Other feature is the logic-compatible shutdown input
which enable the regulator to be switched on and off.
The GL2951 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.
The GL2950 is offered in 3-pin TO-92 package compatible
with other fixed regulator.
