How much current can the STLink/V2 supply on its Vapp pin?

Hi

Can the STLINK/V2 act as a power supply a small board with only an STM32F302 on it (without power supply) during the programming? I dont find any ''tech specs'' or any info on the current sourcing capability of the STLink/V2 in the relevant docs, which is why I ask this. Please pardon an utter newbie to the STM micros family if this is a dumb query.

Based on other designs I'd assume it can supply just under 100mA

Thank you, Clive1. That will work very well for me, since I just need to program the chip :)
