LD39080PT18-R DatasheetThe LD39080 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 BiCMOS process which allows low quiescent current operation independently of output load current.
■ 0.8A Guaranteed output current
■ Ultra low dropout voltage (150mV typ. @ 0.8A load, 20mV typ. @150mA load)
■ Very low quiescent current (1mA typ. @ 0.8A load, 1µA max @ 25°C in off mode)
■ Logic-controlled electronic shutdown
■ Current and thermal internal limit
■ ±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, DPAK and DFN8 (4x4mm)
■ Microprocessor power supply
■ DSPs power supply
■ Post regulators for switching suppliers
■ High efficiency linear regulator
