UNISONIC TECHNOLOGIES CO., LTD LR9200
LOW NOISE 200mA LDO REGULATOR
CMOS IC
DESCRIPTION
The UTC LR9200 is a typical LDO with the features of high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection.
During operation of the UTC LR9200, the dropout voltage is very low and the response of line transient and load transient are very well.
Internally, there’re many functions of UTC LR9200 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 LR9200.
