Note:

The voltage regulator output cannot be used to drive external circuits. Output pins are to be

used only for decoupling capacitance.

VDD_LV_COR must be generated using internal regulator and external NPN transistor. It is

not possible to provide VDD_LV_COR through external regulator.

For the SPC560P34/SPC560P40 microcontroller, capacitor(s), with total values not below

CDEC1, should be placed between VDD_LV_CORx/VSS_LV_CORx close to external ballast

transistor emitter. 4 capacitors, with total values not below CDEC2, should be placed close to

microcontroller pins between each VDD_LV_CORx/VSS_LV_CORx supply pairs and the

VDD_LV_REGCOR/VSS_LV_REGCOR pair . Additionally, capacitor(s) with total values not below

CDEC3, should be placed between the VDD_HV_REG/VSS_HV_REG pins close to ballast

collector. Capacitors values have to take into account capacitor accuracy, aging and

variation versus temperature.

All reported information are valid for voltage and temperature ranges described in

recommended operating condition, Table 10 and Table 11.
