Preliminary CMOS IC
1A CMOS LOW DROPOUT VOLTAGE
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.
