DESCRIPTION

This three terminal positive adjustable voltage regulator is designed to provide 1.5A

with higher efficiency than conventional voltage regulators. This device is designed

to operate to 1 Volt input to output differential and the dropout voltage is specified as

a function of load current. Supplied in easy-to-use hermetic TO-257, TO-3 and

TO-39 packages, this device is ideally suited for Military applications where small size

and high reliability is required.
