capacitor with no esr value

Re: capacitor with no esr value

I too have a EDS88A, works flawlessly. Replace the cap its either open or shorted

Re: capacitor with no esr value

The Fixed or Adjustable regulator body look the same. How they are connected are not the same
The one in this picture is a fixed regulator since I do not see a resistor between pin1 (left pin) and Ground and another resistor between pin1 and pin 2 (middle pin/or large tab), I can see that pin 1 is tied directly to Ground, that is how Fixed output regulator is used.
By the way, I can faintly see 1117 ???? on the body. What is the number?

It's a FMC1117

Re: capacitor with no esr value

I see some marking on the second line on the body.
Measure the resistance between pin 1 and ground as shown in the picture.

Re: capacitor with no esr value

pin on is first one left side

I get 00.06

Re: capacitor with no esr value

That is not completely less than one Ohm, what resistance of the your meter's probes when you short the Red and Black probe together?
And what are the printing on the second line on that regulator?

Re: capacitor with no esr value

I just updated the reading on post 85

Re: capacitor with no esr value

OK, that is more like it, that is a fixed output regulator. The second line on the body should indicate the output voltage of this regulator. What are the Voltage at the input and output pins any way?

Re: capacitor with no esr value

in 05.02
out 3.283
I re tested pin1 0000

I replace batteries in meter

Re: capacitor with no esr value

It looks like to be 3.3V fixed regulator.

It looks like to be 3.3V fixed regulator.

How would I know what bad voltage reading would be on a regulator
would it be on the data sheet for the regulator.

Would it be if the out pin is less then 3.3volts it could be bad ?

Thanks for all the great info

I replaced fixed regulators with an adjustable regulator and still same problem
