An identification lm79p12 the calibration method eg. Regarding capital letters, I empathize with a certain unhappiness about long winded collection of very basic information. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter.

Please contact our partner Intertek directly for a re-calibration of your device: You need to register to use this feature. Available in TO package only. Input and common is swapped on the compared to the Our expert team have over 25 years experience solving problems and providing expert advice. Calibration involves comparing the read values of a measuring instrument or data recorder with the corresponding values of a reference tool that meets the reference standards.

Are you applying a sensible minimum load current to ensure that through-leakage can be “soaked up” at the set output voltage? Save this product to the following list s. I use the proper capacitors for filtering and stability by the application note ST semiconductor’s datasheet. Originally Posted by pjmelect.

Output schottky clamp to ground can prevent it safely. I don’t understand it. Last edited by KlausST; 18th February at How do you get an MCU design to market quickly?

The schematic of the uses inside resistors in the feedback loop to maintain the output voltage R17,R19 on the figure. So I don’t think this is the cause.
