Description
GM7130 of regulators provides all the active

line and load regulation. GM7130 is available
in fixed output voltages of 3.3V, 5V, 12V

power supplies. GM7130 guarantees ±4%
input voltages and output load conditions,
External shutdown is induced with 50 uA
(typical) standby current. The output switch
has cycle-by-cycle current limiting as well
functions for a step- down (buck) switching
version. These regulators are simple to use
and require a minimum number of external
components. Features include internal fre-
quency compensation and a fixed-frequency
oscillator.
The GM7130 is high-efficiency replacements
for popular three-terminal linear regulators,
