Hi Forum:
I am using the ADP160 (www.analog.com/ADP160), specifically the TSOT packaged version with a fixed output voltage of 2.5V. The input to this device is a 5V regulated supply. I am expecting 2.5V at the output of the ADP160, but I am in fact getting about 2.9V. I have checked the input, and this is working fine at a measured 4.96V. Does anyone have an idea of what may cause the voltage to be higher than expected? I would think if there was a path to ground at the output, that the voltage would be lower than expected, or that the part would simply fail. The 2.5V output is being used as a reference voltage to some 5V op amps that can receive a mid-rail reference. Any thoughts on places to look for debug?
Thanks!
