Preliminary
1.5A CMOS LDO
„ DESCRIPTION
The UTC L11815B is a positive, linear regulator. One of its
features is the very low quiescent current typically as low as 45μA
and the dropout voltage is extremely low.
The internal circuit includes thermal shutdown and current
fold-back mechanism to prevent device failure when the circuit is
operated in the bad conditions.
In application, the UTC L11815B needs a low noise and
regulated supply. For stability, the output capacitance value should
be 4.7μF or more.
The UTC L11815B is an ideal for battery applications, such as
instrumentations, portable electronics, wireless devices, cordless
phones, PC peripherals, and battery powered widgets. The output
voltage values are set during manufacturing and their accuracy is
trimmed to within 1.5%.
„ FEATURES
* Quiescent Current (45μA typ.)
* Accurate :±1.5%
* Very Low Dropout Voltage
* Guaranteed 1.5A Output
* Over-Temperature Shutdown
* With Current Limiting
* Short Circuit Current Fold-Back
* Power-Saving Shutdown Mode
* Low Temperature Coefficient
* Halogen Free
