1FEATURES DESCRIPTIONThe LP3874-ADJ fast ultra low-dropout
Ultra Low Dropout Voltage regulators operate froma +2.5V to +7.0V
• Low Ground Pin Current supply. These ultra low dropout linear regulators
Load Regulationof 0.04% respond very quicklyto step changesin load,
makes them suitable for low voltage microprocessor
• 10nA Quiescent Currentin Shutdown Mode applications. The LP3874-ADJis developed
• Specified Output Currentof 0.8A DC CMOS process which allows low quiescent
• Availablein DDPAK/TO-263, TO-220 and SOT- operation independentof output load current.
223 Packages CMOS process also allows the LP3874-ADJ
operate under extremely low dropout conditions.
• Minimum Output Capacitor Requirements Overtemperature/Overcurrent Protection Dropout Voltage: Ultra low dropout voltage; typically
24mVat 80mA load current and 240mVat 0.8A load
• −40°Cto +125°C Junction Temperature Range current.
APPLICATIONS Ground Pin Current: Typically 6mAat 0.8A load
current.
• Microprocessor Power Supplies
Shutdown Mode: Typically 10nA quiescent current
• GTL, GTL+, BTL, and SSTL Bus Terminators when the shutdown pinis pulled low.
• Power Supplies for DSPs
Adjustable Output Voltage: The output voltage may
• SCSI Terminator be programmed via two external resistors.
