Posted on March 28, 2013 at 16:31I am using the L4931 VLDO regulator in my circuit, to regulate form 12.5VDC input to 3.3VDC
The part number that I am using is the L4931ABDT33 with the correct input and output capacitors as stated in the datasheet test circuit.
The problem is that the output voltage is 4.15V open circuit and when drawing a 10mA load it is 4.17V
This is a lot higher than expected and 3 different regulators all produce the same output voltage. Do I have three faulty units (hihgly unlikely) or am I missing something in the regulator circuit?
