Datasheet for the 78LXX family of low-power positive fixed voltage regulators, as a 197 KB PDF. The series covers outputs such as 5 V, 6 V, 8 V, 9 V, 12 V and 15 V, with the last digits of the part number giving the voltage, and handles roughly 100 mA in small TO-92 or SO-8 packages. Use it to check pinout, dropout and input range. Note that TO-92 pin order differs from the larger 78xx in TO-220, so verify against the document before replacing a part or probing input and output.
