Description

150mA CMOS LDO regulator in a 5-lead SOT-23 package,

featuring 120mV dropout at 100mA levels and nearly

negligible 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.
