1FEATURES DESCRIPTION

The LP3963/LP3966 seriesof fast ultra low-dropout Ultra Low Dropout Voltage linear regulators operate froma +2.5Vto +7.0V input• Low Ground Pin Current supply. Wide rangeof preset output voltage options Load Regulationof 0.06% are available. These ultra low dropout linear
regulators respond very quicklyto step changesin• 15µA Quiescent Currentin Shutdown Mode load which makes them suitable for low voltage• Specified Output Currentof 3A DC microprocessor applications. The LP3963/LP3966 are• Availablein DDPAK/TO-263 and TO-220 developed ona CMOS process which allows low

quiescent current operation independent of output
load current. This CMOS process also allows the• Output Voltage Accuracy± 1.5% LP3963/LP3966 to operate under extremely low• Error Flag Indicates Output Status (LP3963) dropout conditions.• Sense Option Improves Load Regulation Dropout Voltage: Ultra low dropout voltage; typically(LP3966) 80mVat 300mA load current and 800mVat 3A load• Minimum Output Capacitor Requirements current. Overtemperature/Overcurrent Protection Ground Pin Current: Typically 6mA at 3A load• −40°Cto +125°C Junction Temperature Range current.
Shutdown Mode:
Typically 15µA quiescent currentAPPLICATIONS when the shutdown pinis pulled low. Microprocessor Power Supplies Error Flag: Error flag goes low when the output• GTL, GTL+, BTL, and SSTL Bus Terminators voltage drops 10% below nominal value (for LP3963). Power Supplies for DSPs SENSE: Sense pin improves regulation at remote• SCSI Terminator loads. (For LP3966) Post Regulators Precision Output Voltage: Multiple output voltage• High Efficiency Linear Regulators options are available ranging from 1.2Vto 5.0V and
