800mA
CMOS LDO
DESCRIPTION
Preliminary
CMOS IC
As UTC LDO, the features of the UTC L1188 include low quiescent current and very low dropout
voltage. In order prevent form the bad operating conditions, there are internal thermal shutdown and current fold-back. For stably operation, the UTC L1188 should be connected to an output capacitance of 2.2μF or larger. The UTC L1188 can be an ideal for battery applications, such as portable electronics, wireless devices, cordless phones, PC peripherals and battery powered widgets.
