LR9283
LR9283 is 300mA LDO REGULATOR manufactured by Unisonic Technologies.
DESCRIPTION
The UTC LR9283 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 LR9283 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 LR9283.
The output voltage of these ICs is fixed with high accuracy.
