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. 1 FEATURES
