What can I do to improve load regulation on VR2?

    At high loads, above 2A, the VR2 can become out of specification if shorted to GND with low resistance.

    To correct this issue, simply add a 100 Ohm resistor from the GND of the output caps or negative feedback point to the FBVR2N pin on the device. By doing this the load regulation will stay with in specified limits until current limit is reached.
