LT1027C Negative 5V support


I am using LT1027 part in one of re design project in existing design by using this part generating negative 5V output by connecting Negative 15V to ground pin and supply pin to ground.

I am going through datasheet there is no specific details mentioned about negative output.

Please conform on is this part generate negative output and if any application notes available please share.

    HI Vinayak Arkachari,

    I would not recommend doing it in this design. Looking at the Absolute Maximum Rating, it can be seen that output to Ground Voltage should be limited to 7V but in this setup it will be -20V.
    If you want to build a negative voltage using the LT1027, you could use the bipolar circuit setup from the ADR45xx datasheet.
