ADP2108-3.0 output at 1V

Hi,

 

I have the same situation as several other posters with an ADP2108-3.0 whose output sits at about 1V.  With the output at 1V, my circuit is drawing about 45 mA.

 

I have added a 4.7 uF X5R 0603 input capacitor across Vin and ground, still doesn't work.  If I disconnect the output load (I have a series current sampling resistor), the output sits at 3.0V like it should.  The circuit is on a 6-layer PCB,Image may be NSFW.
Clik here to view.

There is a dedicated ground layer.  I've used one of the recommended inductors, and 10 uF tantalum input and output capacitors (before adding the 4.7 uF ceramic input cap).

 

Thanks,

Scott
