Preliminary Data Sheet
FEATURES
• Hermetic Surface Mount Package
• Operates Down To 1V Dropout, 1.5V @ Max. Current
• .015% Line Regulation
• .01% Load Regulation
• 1% Reference Voltage
• Electrically Equivalent To LT1083, 84, 85, And 86
• Available Hi-Rel Screened
DESCRIPTION
These three terminal positive fixed voltage regulators in surface mount packages are
designed to provide 7.5A, 5A, 3A, and 1.5A with higher efficiency than conventional
voltage regulators. These devices are designed to operate to 1 Volt input to output
differential and the dropout voltage is specified as a function of load current. These
devices are ideally suited for Hi-Rel applications where surface mount, small size,
hermeticity and high reliability are required.
