(1) _{Reset is always generated after a tTEMP delay. The application must ensure that VDD is still above the}
minimum ooperating voltage (V_DD min) when the t_TEMP delay has elapsed.

VCAP external capacitor
Stabilization for the main regulator is achieved connecting an external capacitor C_EXT to the
V_CAP pin. C_EXT is specified in the Operating conditions section. Care should be taken to limit
the series inductance to less than 15 nH.
