Min negative voltage

Category: Hardware
Product Number: LT1611

Hello,

The LT1611 is normally used to generate -5V from 5V.

But if I change the R2 resistor to 68k while keeping R1 at 10K, the output should be -10V.

With a load of 10mA, it should be OK.

But when I tried it does not work and I got -20V.

Is my assumption OK to get -10V from the LT1611 ?

Thank you, Regards,

Laurent
