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 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.
FEATURES
* Accurate To Within 1.5%
* Quiescent Current: 30μA
* With Current Limiting
* Internal Short Circuit Current Fold-Back
* Has Power-Saving Shutdown Mode
* Very Low Temperature Coefficient
