UNISONIC TECHNOLOGIES CO., LTD LR9102/A LOW NOISE 300mA LDO REGULATOR 3 CMOS IC 4 5  DESCRIPTION The UTC LR9102/A is a typical LDO (linear regulator) with the features of high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. During operation of the UTC LR9102/A, 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 LR9102/A 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 LR9102/A, with auto discharge function at off state.
