Overview
UNISONIC TECHNOLOGIES CO.
, LTD L1131A LOW NOISE 150mA LDO REGULATOR  DESCRIPTION The UTC L1131A is a COMS positive linear regulator.
One of it’s feature is the very low quiescent current typical as low as 10μA and its dropout voltage is extremely low with 150mA output current, and high ripple rejection.
Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, a short current limit circuit, a chip enable circuit, and so on.
These ICs perform with low dropout voltage and the chip-enable function.
The supply current at no load of this IC is only 4.
3μA, and the line transient response and the load transient response of the UTC L1131A Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment.
The output voltage of these ICs is fixed with high accuracy.
Since the packages for these ICs are SOT-23-5 therefore high density mounting of the ICs on boards is possible.
