DESCRIPTION
This three terminal positive adjustable voltage regulator is designed to provide 3.0A 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, SMD-1 or TO-3
packages, this device is ideally suited for Military applications where small size and high
reliability is required.
