Reset Logic Output. RESET is the inverse of RESET (LM3707 only).
Low-Line Logic Output. Early Power-Fail warning output. Low when V
(Low-Line Output Threshold). This output can be used to generate an NMI (Non-Maskable
Interrupt) to provide an early warning of imminent power-failure.
Ground reference for all signals.
