These ultra low dropout linear regulators • Load Regulation of 0.08% respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor • 1µA Quiescent Current in Shutdown Mode applications. The LP3876-ADJ is developed on a • Specified Output Current of 3A DC CMOS process which allows low quiescent current • Available in DDPAK/TO-263 and TO-220 operation independent of output load current. This Packages CMOS process also allows the LP3876-ADJ to operate under extremely low dropout conditions. • Minimum output Capacitor Requirements • Overtemperature/Overcurrent Protection Dropout Voltage: Ultra low dropout voltage; typically 80mV at 300mA load current and 800mV at 3A load • −40°C to +125°C Junction Temperature Range current. APPLICATIONS Ground Pin Current: Typically 6mA at 3A load current. • Microprocessor Power Supplies Shutdown Mode: Typically 1µA quiescent current • GTL, GTL+, BTL, and SSTL bus terminators when the shutdown pin is pulled low. • Power Supplies for DSPs Adjustable Output Voltage: The output voltage may • SCSI Terminator be programmed via two external resistors. • Post Regulators • High Efficiency Linear Regulators • Battery Chargers • Other Battery Powered Applications TYPICAL APPLICATION CIRCUIT *See Application Hints 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
