Description
The L9777 is a monolithic integrated low drop
regulator which can supply up to 200 mA,
available in the PowerSSO-12 package.
It is designed to supply microprocessor systems
under severe conditions of automotive
applications and therefore equipped with
additional protection functions against over load,
short circuit and over temperature.
Of course the L9777 can also be used in other
applications where a regulated voltage is
required.
