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

These devices are ideally suited for Military applications where small size, hermeticity

and high reliability are required.
