(1) Reset is always generated after a tTEMP delay. The application must ensure that VDD is still above the

minimum ooperating voltage (VDD min) when the tTEMP delay has elapsed.

VCAP external capacitor

Stabilization for the main regulator is achieved connecting an external capacitor CEXT to the

VCAP pin. CEXT is specified in the Operating conditions section. Care should be taken to limit

the series inductance to less than 15 nH.
