? 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.
