UNISONIC TECHNOLOGIES CO., LTD L1131C Preliminary LOW NOISE 150mA LDO REGULATOR CMOS IC „ DESCRIPTION The UTC L1131C 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 normal operation of UTC L1131C, the dropout voltage is very low, and the response of line transient and load transient are very well. Inside each UTC L1131C, there’re many functions which can be seen in the block figure, for example, a voltage reference unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.
