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’s new surface mount D2 Pac..
These devices are ideally suited for Military applications where small size, hermeticity
and high reliability are required.
