General Description
TS1123 is a low dropout voltage regulator driver for various electronic equipments. It provides constant voltage power
source with SOT-25 package. TS1123 with external PNP transistor can drive output current up to 4A, quiescent
current is typically at 5mA. Further more, the quiescent current is smaller when the regulator is in the dropout mode
(VIN<5.5V). TS1123 has various functions such as a over current protection, thermal shutdown and an output enable
function.
