QW-R502-422.C

300mA CMOS LDO



DESCRIPTION

The UTC L1183B is a positive, linear regulator. One of the feature

is the very low ground current typically as low as 30μA, and the

dropout voltage is extremely low. For stable operation, the output

capacitance value should be 2.2μF or more.

The internal circuit includes thermal shutdown and current

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

operated in bad conditions.

The UTC L1183B is generally suitable for applications, such as

instrumentation, portable electronics, wireless devices, cordless

phones, PC peripherals, battery powered widgets.
