L78M09CV (L7809CV) TO-220 Linear Voltage Regulator

The L78M09CV is a
fixed output, three terminal precision positive voltage regulator in 3
pins TO-220 package. This regulator can provide local on-card regulation
by eliminating distribution problems associated with single point
regulation. The L78M09CV fixed voltage regulator is designed with
thermal overload protection that shuts down the circuit when subjected
to an excessive power overload condition, internal short circuit
protection that limits maximum current the circuit will pass and output
transistor safe area compensation that reduces the output short circuit
as the voltage across the pass transistor is increased. If adequate heat
sinking is provided then this positive voltage regulator can deliver
over 0.5A output current.
