150mA LDO REGULATOR



DESCRIPTION

The UTC LR9280 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 LR9280

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 LR9280.

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

version has a chip enable pin, therefore low consumption current

standby mode can be realized with the pin.


