DESCRIPTION
The OM2990 series of fixed voltage regulators are designed to provide up to 1.5A with
h g e i i n y. It has the ability to source 1A of output current with a typical dropout
i h ff c e c
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.
