Hey brains I have a question.
I'm designing a 5V circuit. Considering the 78L05 (TO-92) and 7805 (TO-220).
The L05 is rated at 100ma while the 05 comes in 1a and 1.5 versions.
Is there anything in between? 100ma is not quite enough while the 7805
is overkill.
Space is a concern so I like the TO-92 package.
If I'm reading the datasheet right for a 7 segment display it draws
25-30ma for each
segment? Thats a current draw of 250ma if all segments are lit.
Therefore I may have
to use the 7805/C or change my design to use dual state LED (17-22ma)
instead of the 7 segment LED.
