Hi All,

I have a problem and maybe you can help me.

I've designed a board with two LM1117 LDO regulators which are set to 3.3V
and 1.8V they work fine... except that they both draw 5.1mA in quiescent
current which makes my battery driven application useless... (I know it is
stated in the datasheet but I didn't think when I made the decision to use
it)

The housing for these monsters are TO-252 arranged in this way:

Pin:

  3 Voltage input
2   Voltage output
  1 Adjust pin

Where pin 2, is the tap and the footprint is viewed from above.

I will never draw more than 75mA in my application on the 3.3V rail and
about 5mA on the 1.8V rail

If you've heard of any regulator with a lower quiescent current please speak
up I've been searching the net for hours now but unable to find anything...

Even a leaded TO92 style regulator would be fine as I'm desperate...

Best regards
Lasse Madsen
