Features
Description
Maximum output current: 300mA
Highly accurate: Output voltage ±2%
Low power consumption.
Over -Current and Over-Temperature
protection
GM6350 is a group of positive voltage output, three - pin
regulators, that provide a high current even when the input/
output voltage differential is small. Low power consumption
and high accuracy is achieved through CMOS and pro-
grammable fuse technologies. Output voltage: 1.5V to
5.0V.
Small input/ output differential:
0.3V at 300mA
GM6350 consists a high-precision voltage reference, an er-
ror correction circuit, and a current limited output driver.
Transient response to load variations have improved in
comparison to the existing series.
GM6350 incorporates both over-temperature and over-
current protection.
