LR2125

300mA SELECTABLE

FIXED/ADJUSTABLE LOW

DROPOUT LINEAR REGULATOR



DESCRIPTION

LINEAR INTEGRATED CIRCUIT

As a low dropout linear regulator, the UTC

LR2125

only needs

low input voltage (2.8~6V) and can deliver current to 300mA for

setting the output voltage.

The UTC

LR2125

is an ideal for being used in such

battery-powered equipments notebook, personal computer and

cellular phone. Its typical dropout voltage is 230mV at loading current

300mA.

For setting the output voltage, the UTC

LR2125

has two output

voltage operation modes: fixed mode senses the output voltage on

OUT

, ADJ mode needs two resistors as a voltage divider.

To protect itself against current over-loads and over temperature,

the

LR2125

has current limit and thermal shutdown functions.



FEATURES

* Operating Voltage: 2.8~6V

* Low Voltage Dropout

* Output Current Guaranteed 300mA

* For Setting Output Voltage Two Modes

–

Fixed mode :Fixed Output Voltage 1~5V

–

ADJ mode: Adjustable Output Voltage 0.8~5.5V

* Internal Current Limit Protection

* With Soft-Start

* Internal thermal Protection

* Work stably with Low ESR Ceramics Capacitor
