FEATURES - 2 Ultra Low Dropout Voltage - Low Ground Pin Current - Load Regulation of 0.04% - 10n A Quiescent Current in Shutdown Mode - Specified Output Current of 0.8A DC - Available in DDPAK/TO-263, TO-220 and SOT- 223 Packages - Minimum Output Capacitor Requirements - Overtemperature/Overcurrent Protection - - 40°C to +125°C Junction Temperature Range APPLICATIONS - Microprocessor Power Supplies - GTL, GTL+, BTL, and SSTL Bus Terminators - Power Supplies for DSPs - SCSI Terminator - Post Regulators - High Efficiency Linear Regulators - Battery Chargers - Other Battery Powered Applications DESCRIPTION The LP3874-ADJ fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply. These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3874-ADJ is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3874-ADJ to operate under extremely low dropout conditions. Dropout Voltage: Ultra low dropout voltage; typically 24m V at 80m A load current and 240m V at 0.8A load current. Ground Pin Current: Typically 6m A at 0.8A load current. Shutdown Mode: Typically 10n A quiescent current when the shutdown pin is pulled low. Adjustable Output Voltage: The output voltage may be programmed via two external resistors.
