LM340T-12

The LM340 and LM7805 Family monolithic 3-terminal
positive voltage regulators employ internal currentlimiting, thermal shutdown and safe-area
compensation, making them essentially indestructible.
If adequate heat sinking is provided, they can deliver
over 1.5-A output current. They are intended as fixed
voltage regulators in a wide range of applications
including local (on-card) regulation for elimination of
noise and distribution problems associated with
single-point regulation. In addition to use as fixed
voltage regulators, these devices can be used with
external components to obtain adjustable output
voltages and currents
