1. The external components connected to the pin must be chosen to avoid that the voltage exceeds this
operative range.
2. Load regulation is calculated at a fixed junction temperature using short load pulses covering all the load
current range. This is to avoid change on output voltage due to heating effect.
3. Undervoltage rising and falling thresholds are intended as a percentage of feedback pin voltage
(V_{LINmain_Ref}).
