Narrative:

This was our first leg and I believe our first time flying with an inoperative idg. During our climbout with the above referenced MEL; I went through my normal after takeoff flow. As I pushed in the APU start/stop button I realized my mistake. The APU needs to be on for the duration of the flight. Several cas messages came on as the load shedding kicked in. I waited one minute and restarted the APU. I then applied the QRH to turn on the shed systems.it may be beneficial for this and other mels to have operational stickers that are placed next to other affected components during an MEL. In this case an 'on' sticker next to the APU as well as an 'on' sticker next to hydraulic pump 1B would have been helpful.

Title: Dispatched with one IDG inoperative; the Captain of a CRJ-200 inadvertently shut down the APU per normal SOP after takeoff; reducing the aircraft to a single AC power source and resulting in the shutdown of several systems due to load shedding. Restarting the APU resolved the problem.
