HIGH INPUT VOLTAGE, LOW

QUIESCENT CURRENT,

300mA LDO REGULATOR

DESCRIPTION

The UTC LM5954 is a low ground current linear regulator which

operates with input voltage from 6.5V ~ 25V and delivers output

current up to 300mA. Typical dropout voltage is only 450mV at

300mA loading.

The UTC LM5954 has many protection functions including over

temperature and current limit which prevent the device from

thermal over-load and current over-load.

FEATURES

* Wide Operating Voltage : 6.5V~25V

* Ultra Low Ground Current :120μA

* High Output Accuracy : ±2% over temperature

* Excellent Load/Line Transient

* Low Dropout Voltage : 450mv @ 300mA

* Built-in Current Limit Protection

* Built-in Over Temperature Protection

* Zero Shutdown Current
