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

VOUT, 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.


