Voltage regulator electrical characteristics
The internal voltage regulator requires an external NPN ballast to be connected as shown in Figure 8. Table 14 contains all
approved NPN ballast components. Capacitances should be placed on the board as near as possible to the associated pins. Care
should also be taken to limit the serial inductance of the VDD_HV_REG, BCTRL and VDD_LV_CORx pins to less than LReg, see
NOTE
The voltage regulator output cannot be used to drive external circuits. Output pins are used
only for decoupling capacitances.
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 MPC5604P microcontroller, capacitors, 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, capacitors 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 8
