Preliminary

LINEAR INTEGRATED CIRCUIT

300mA SELECTABLE

FIXED/ADJUSTABLE LOW

DROPOUT LINEAR

REGULATOR



DESCRIPTION

As a low dropout linear regulator, the UTC LR2128 only needs

low input voltage (2.7~6V) and can deliver current to 300mA for

setting the output voltage.

SOT-25

The UTC LR2128 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 LR2128 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 UTC LR2128 has current limit and thermal

shutdown functions.


