Description
General part information
LD39150 Series
The LD39150 is a fast ultra low drop linear regulator which operates from 2.5 V to 6 V 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.1.5 A guaranteed output currentUltra low dropout voltage (200 mV typ. @ 1.5 A load, 40 mV typ. @ 300 mA load)Very low quiescent current (1 mA typ. @ 1.5 A load, 1 µA max @ 25 °C in off mode)Logic-controlled electronic shutdownCurrent and thermal internal limit± 1.5% output voltage tolerance @ 25 °CFixed and ADJ output voltages: 1.8 V, 2.5 V, 3.3 V, ADJTemperature range: -40 to 125 °CFast dynamic response to line and load changesStable with ceramic capacitorAvailable in PPAK, DPAK and DFN6 (3x3 mm)
