DESCRIPTION
These three terminal fixed voltage regulators are designed to provide 1.0A with high
efficiency. It has the ability to source 1A of output current with a typical dropout
voltage of .5V and a maximum of 1V over the entire temperature range. It is supplied
in a hermetic surface mount package and is ideally suited for Military applications
where small size and high reliability are required.
