300mA CMOS LDO

DESCRIPTION

The UTC L1183A is a COMS positive linear regulator. One of

it’s feature is the very low quiescent current typical as low as 30μA

and its dropout voltage is extremely low with 300mA output current.

The internal circuit includes thermal shutdown and current

fold-back to prevent device failure when the circuit is operated in the

bad conditions.

In application, the UTC L1183A needs a low noise, regulated

supply. For stable operation, the output capacitance value should be

2.2μF or more.

The UTC L1183A is an ideal for battery applications, such as

instrumentations, portable electronics, wireless devices, cordless

phones, PC peripherals, and battery powered widgets.
