An LM2930 or LM2940 in TO-220 package is pinout-compatible with the familiar 78xx series in TO-220.
The 78Lxx 100mA devices in TO-92 are "backwards" - output is the left-most and input is the right-most pin, as you look at the front of the device.
But ground is still the middle pin - you can still use them on the TO-220 footprint, if the 100mA output is adequate.
Splay the leads out a bit so that the TO-92 leads fit into the TO-220 holes, and flip the device around so that pin 1 and pin 3 are swapped.
