ETC X7812

X78XX
The X7805 series of three-terminal positive regulators
are available in TO-220 package and with several fixed
output voltage, making them useful in a wide range of
application. Each type employs internal current limiting,
thermal shut-down and safe area protection, making it
essentially indestructible. If adequate heat sinking is
provided ,they can deliver over 1.5A output current, Although
designed as fixed voltage regulators, these devices can be
used with external components to obtain adjustable voltage
and currents.
