LR2125

LINEAR INTEGRATED CIRCUIT

300mA SELECTABLE

FIXED/ADJUSTABLE LOW

DROPOUT LINEAR REGULATOR



DESCRIPTION

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

V_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
