 		 #146840 - Don't omit the input cap!
Responding to: ???'s previous message
Please don't omit the decoupling cap at input of 78L05 in this circuit:

http://www.ece.ubc.ca/~jesusc/LPC925C.pdf

The battery doesn't provide any high frequency decoupling and even if so, the diode would isolate the 78L05 from it. So, please always add a cap also to the input of 78L05. Omitting it is bad design practice.
