DESCRIPTION

The OM2990 series of fixed voltage regulators are designed to provide up to 1.5A with

high efficiency.

It has the ability to source 1A of output current with a typical dropout

voltage of 0.6V and a maximum of 1V over the entire operating temperature range.

It is

supplied in hermetic packages and is ideally suited for all applications where small size

and high reliability are required.
