3 Description

The LP38690 and LP38692 low-dropout CMOS linear

regulators provide tight output tolerance (2.5%

typical), extremely low dropout voltage (450 mV at a

1-A load current, VOUT = 5 V), and excellent AC

performance utilizing ultra low ESR ceramic output

capacitors.

The low thermal resistance of the WSON, SOT-223,

and TO-252 packages allow the full operating current

to be used even in high ambient temperature

environments.

The use of a PMOS power transistor means that no

DC base drive current is required to bias it allowing

ground pin current to remain below 100 μA

regardless of load current, input voltage, or operating

temperature.
