Note:
3.18. Thermal and Overload Protection
The IC continuously observes its silicon die temperature. If the temperature rises above around 140°C for
more than 2 seconds the IC will be put into shutdown and stay there until the next power-on reset occurs.
The circuit also becomes shut down if U

The decoupling capacitor defines an internal low-pass filter time constant; lower values decrease the impedance but improve
the turn-on time. Higher values do not improve the impedance but do increase the turn-on time.
The turn-on time also depends on the load capacitor at UOUT. After connecting the slave to the power the capacitor is charged
with the maximum current I
