Operates Down to 1V Dropout, 1.5V @ Max. Current
.015% Line Regulation
.01% Load Regulation
1% Reference Voltage
Hermetic TO-257 and TO-258 Isolated Packages
Electrically Equivalent to LT1083, 84, 85 and 86
DESCRIPTION
These three terminal positive adjustable voltage regulators are designed to provide
7.5A, 5A, 3A, and 1.5A with higher efficiency than conventional voltage regulators. The
devices are designed to operate to 1 Volt input to output differential and the dropout
voltage is specified as a function of load current. All devices are pin compatible with
older three terminal regulators. Supplied in the easy-to-use hermetic metal TO-257
and TO-258 JEDEC packages also supplied in Omnirel鈥檚 new surface mount D
2
Pac..
These devices are ideally suited for Military applications where small size, hermeticity
and high reliability are required.
