Does anyone know of a different chip besides the LM317 that does the same thing but will accept a lower voltage input. The reason I ask is because the LM317 has a drop of 2 volts. I was making my Dorcy Metal Gear last night and was testing it with Daedal's circuit. Everything fit nicley in the Dorcy but with only 4.5 volts from the Dorcy, the LD was only drawing like 40 mA. So I had to leave the LM317 out. So with a 5 ohm resistor, a 47 uF capacitor, and the silicone diode, with an input of 4.5 volts, the LD draws a nice and comfortable 160 mA. I would like to have this regulator in their for added security. If anyone knows a different regulator that would work with 4.5 volts, please share your thoughts. Thank You.
