LOW NOISE 200mA LDO REGULATOR

DESCRIPTION

The UTC L1131B is a COMS positive linear regulator. One of
it’s feature is the very low quiescent current typical as low as 1.5μA
and its dropout voltage is extremely low with 200mA 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 1.5μA, and
the line transient response and the load transient response of the
UTC L1131B Series are excellent, thus these ICs are very suitable
for the power supply for hand-held communication equipment.
