LP38692-ADJ Datasheet 1-a Low Dropout CMOS Linear Regulator

Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community Reference Design LP38690-ADJ, LP38692-ADJ SNVS323I – DECEMBER 2004 – REVISED FEBRUARY 2016 LP3869x-ADJ 1-A Low Dropout CMOS Linear.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LP38690-ADJ and LP38692-ADJ low dropout CMOS linear regulators provide 2.5% precision reference voltage, extremely low dropout voltage (450 mV at 1-A load current, VOUT = 5 V) and excellent AC performance utilizing ultralow equivalent series resistance (ESR) ceramic output capacitors.

The low thermal resistance of the WSON and SOT223 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.
