300mA LDO REGULATOR

DESCRIPTION

The UTC LR9282A is a typical LDO (linear regulator) with the

features of high output voltage accuracy, low supply current, low

ON-resistance. Internally, there’re many functions of UTC

LR9282A which can be seen in the block figure. There are a

voltage reference unit, an error amplifier, resistor-net for voltage

setting, a current limit circuit, and a chip enable circuit in each

UTC LR9282A.

The output voltage of these ICs is fixed with high accuracy.

FEATURES

* Output voltage accuracy (±1%)

* Output voltage range (0.8V~5V)

* Dropout voltage (TYP=290mV )(IOUT=100mA, VOUT=1.8V Output type)

* Line regulation (TYP=0.2%/V)

* Built-in fold-back protection circuit (TYP=15mA)  (Current at short mode)
