UNISONIC TECHNOLOGIES CO., LTD LR9270 800mA LDO REGULATOR CMOS IC 1  DESCRIPTION The UTC LR9270 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 LR9270, 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 LR9270 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 LR9270.
