Description

This OM3914STM is designed to provide 3A with higher efficiency than conventional voltage regulators. This device is designed to operate down to 1 Volt input to output differential and the dropout voltage is fully specified as a function of load current. Supplied in easy-to-use hermetic TO-257 and TO-3, this OM3914STM is ideally suited for Military applications where small size and high reliability is required.
