Preliminary
1A CMOS LOW DROPOUT
VOLTAGE
CMOS IC
„ DESCRIPTION
As UTC LDO, the features of the UTC L11810 include low
quiescent current and very low dropout voltage.
In order to prevent from the bad operating conditions, there are
internal thermal shutdown and current fold-back. For stably operation,
the UTC L11810 should be connected to an output capacitance of
2.2μF or larger.
The UTC L11810 is ideal for battery applications, such as
portable electronics, wireless devices, cordless phones, PC
peripherals and battery powered widgets.
„ FEATURES
* Extra low dropout voltage
* Output current: 1A (guaranteed)
* Output voltage accuracy: ±1.5%
* Quiescent current: 30μA
* Internal Over-Temperature shutdown
* With Current limiting
* Internal short circuit current fold-back
* Pre-set output voltages in factory
* Very low temperature coefficient
