Description

General part information

LP38693-ADJ-Q1 Series

The LP3869x low-dropout CMOS linear regulators provide tight output tolerance (2% typical), extremely low dropout voltage (250 mV at 500-mA load current, VOUT= 5 V), and excellent AC performance using ultralow equivalent series resistance (ESR) ceramic output capacitors.

The low thermal resistance of the WSON, SOT-223, and TO-252 packages allow use of the full operating current 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, thus allowing ground pin current to remain below 100 µA regardless of load current, input voltage, or operating temperature.
