DESCRIPTION

These three terminal positive fixed 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, these devices are ideally suited for Military

applications where small size, hermeticity and high reliability are required.
