GM4275
WIDE INPUT RANGE
5V LOW DROPOUT REGULATOR
WITH RESET FLAG
Description
Features
The GM4275 series of fixed output, micro-power
voltage regulators is designed for applications
„
which require wide input voltage range up to 45V. _„
The GM4275 is an excellent choice for the use in _„
automobile applications with the features of low
quiescent current and low drop output voltage.
„
The GM4275 features the shutdown functions, such ^„
as over temperature protection for further power
„
saving concerns.
„
A reset signal is generated for an output voltage
VQ of typ.4.65 V. The delay time can be
„
programmed by the external delay capacitor.
Output voltage: 5V±2%
Very low current consumption
Power on and under voltage reset
Reset low down to VQ=1V
Very low drop out voltage
Short circuit protection
Reverse polarity protection
Suitable for automotive applications
The GM4275 is in 5-Pin TO263 package.
However, 5-Pin TO252 package is also available
for better board area saving purpose.
