TO-220FPTO-220 D²PAKDPAK Features • Output current up to 1.5 A • Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18; 24 V • Thermal overload protection • Short circuit protection • Output transition SOA protection • 2 % output voltage tolerance (A version) • Guaranteed in extended temperature range (A version) Description The L78 series of three-terminal positive regulators is available in TO-220, TO-220FP, D²PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type embeds 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 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.

I was able to make my list of needed parts and use suggested products. The big plus is the fact they show inventory quantity.

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.
