Watchdog refresh input.
If the square wave frequency at this input pin is too low, a low pulse at
RST pin is generated (just for L99VR01J).
RST

11
Reset output.
It is pulled down when output voltage goes below Vo_th or frequency at
Wi is too low (just for L99VR01J). Leave floating if not used.
VO

12
Voltage regulator output.
Block to ground with a capacitor ≥ 3.3 µF (needed for regulator
stability).
