Default Another LDO replacement for the LM317

I did a little poking around and found another replacement for the LM317. * *The link is:

http://www.linear.com/pc/productDeta...0,C1055,P38503

It's a Linear Tech LTC3080. *

The voltage mode dropout is 300mV
The current mode dropout is 1.35V (plus the drop over a 1 ohm resistor). * For a 200mA current - that's 1.55V minimum drop from the battery to the LD - not too shabby. *See Page 16 of the data sheet.

I just ordered some of these from Linear. They are a 2 wk delivery item, but I will knock off a driver to see how well they perform when I get them.
