The SE78MXX is monolithic fixed voltage regulator
integrated circuit .It is suitable for applications that
required the output current up to 500mA.
This fixed voltage regulators can provide local or
on-card regulation for elimination of noise and
distribution problems associated with single point
regulation.

Fixed Output voltage of 3.3V, 5V, 8.0V, 9.0V
available
Output current up to 500mA
Minimum extemal components.
Output voltage tolerances of +4%
Thermal overload shutdown protection
Short circuit current limiting
ESD rating is 2KV (Per MIL-STD-883D).
