L1183B
Preliminary
300mA CMOS LDO
CMOS IC
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.
