Preliminary
CMOS IC
600mA CMOS LDO
DESCRIPTION
The UTC L1186 is a COMS positive linear regulator. One of its
features is the very low quiescent current typical as low as 30μA and
its dropout voltage is extremely low with 600mA 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 L1186 needs a low noise, regulated
supply. For stable operation, the output capacitance value should be
2.2μF or more.
The UTC L1186 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
* Internal Over-Temperature Shutdown
* With Current Limiting
* Internal Short Circuit Current Fold-Back
* With Noise Reduction Bypass Capacitor
* Has Power-Saving Shutdown Mode
* Very Low Temperature Coefficient
