SE78XX
1A 3-Terminal Positive Voltage Regulator
General Description
Features
The SE78XX series are three terminal
positive voltage regulators designed for a
wide variety of applications including local,
on-card regulation.
The SE78XX is complete with internal
current limiting, thermal shutdown protection,
and safe-area compensation which make
them virtually immune from output overload.
If adequate heat sinking is provided, these
regulators can deliver output currents up to
1A.
The SE78XX are available in TO220 and
TO252 packages.
