LR9280
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.
