Undocumented Triangle Wave Imposed on Vout

Category: Hardware
Product Number: LT3015

Hi,

I'm running a simulation in LTSpice for the LT3015. When I am regulating to a voltage of -1.5V I get this strange triangle waveform imposed ontop of the -1.5Vdc. What's going on? I don't see this documented in the datasheet. I'm suspecting it has something to do with the feedback resistor ratio being less than 1, but I'm not sure.

Thanks,

Ethan
