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.
