RESET CMOS/TTL compatible output lead RESET goes low whenever VOUT drops by

more than 6.0% from nominal, or during the absence of a correct watchdog

signal.

Sense Kelvin connection which allows remote sensing of the output voltage for im-

proved regulation. If remote sensing is not required, connect to VOUT.

*Pin 6 GND is not directly shorted to the fused paddle GND. The fused paddle GND (pins 4, 5, 12, 13) is connected through the substrate.

Pin 6 must be electrically connected to at least one of the fused paddle GND’s on the PC board.
