.. Ultra low drop BICMOS voltage regulator Feature summary - - - - - - - - - - - 3A Guaranteed output current Ultra low dropout voltage (200m V typ. @ 3A load, 40m V typ. @600m A load) Very low quiescent current (1.2m A typ. @ 3A load, 1µA max @ 25°C in off mode) Logic-controlled electronic shutdown Current and thermal internal limit PPAK DPAK ±1.5% Output voltage tolerance @ 25°C Fixed and ADJ output voltages: 1.22V, 1.8V, 2.5V, 3.3V, ADJ. (- see order code) Temperature range: -40 to 125°C Fast dynamic response to line and load changes Stable with ceramic capacitor (see paragraph 7.1, 7.2, 7.3) Available in PPAK and DPAK Description The LD39300 is a fast ultra low drop linear regulator which operates from 2.5V to 6V input supply. A wide range of output options are available. The low drop voltage, low noise, and ultra low quiescent current make it suitable for low voltage microprocessor and memory applications. The device is developed on a Bi CMOS process which allows low quiescent current operation independently of output load current.
