Linear Fixed Voltage Regulator. My soldered in device could go wrong from the V input, but the other device which I measured with labour supply couldn’t. The reading and accuracy of the instruments may change over time. I used about 1mm wide, 35um thick copper on the board, maximum length is about 10cm. With your diode supplements, we would need more words to see clearly how e. I have used a Battery to power the IC, but you can use any power source but notice that the supply voltage should be negative.

LM regulator doesn’t work by dataeheet Hi, not so difficult, sorry, but I thougth a 3 terminal regulator circuit I can describe in words. LM regulator doesn’t work by datasheet Make sure that the input and common are connected correctly.

In collaboration with Intertek, Distrelec is offering a calibration service for new electronic test and measurement instruments. Please contact our partner Intertek directly for a re-calibration of your device: Losses in inductor of a boost converter 9. The “second source” type. I will try to short the ground diode then if it is not help I will buy a new one. Image is for illustrative purposes only. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter.
