SOT-23 CMOS LDO Regulator with Shutdown
General Description
150mA CMOS LDO regulator in a 5-lead SOT-23 package,
featuring 120mV dropout at 100mA levels and nearly negli-
gible dropout below 5mA.
The part offers ±2% precision as standard, yet draws only
5µA of current in operation and drops to 0.5µA in shutdown.
The outputs offer short-circuit protection, and the shutdown
pin has an internal pull-down which will disable the output if
the pin is left floating.
