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.
The UTC L1131C can be used as an ideal of power sou...
