I would like to ask about the input voltage of the LT3090.

Hello. I am a graduate student studying at Chungbuk National University in South Korea.

Nowaday, I used the LT3090 and I made it according to the configuration of the Basic Adjustable Regulator described in Datasheet.

But I did not see the input voltage on the data sheet up to -10V. So I entered -15V with my fault. IC seems to be broken.

The Floating 3-Terminal Adjustable Regulator on the datasheet shows only input voltages from -17V to -22V.

Does the LT3090 have input voltages below -10V? I wonder.

If I can input a voltage below -10V, how should I configure it?
