GM 4275

LDO (Low Current Consumption)

Wide Input Range 5V Low Dropout Regulator With Reset Flag

 

General Description

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.

The GM4275 is in 5-Pin TO263 package. However, 5-Pin TO252 package is also available for better board area saving purpose.
