Voltage regulator electrical characteristics

The internal voltage regulator requires an external NPN (BCP56, BCP68, BCX68 or BC817) ballast to be connected as shown

in Figure 8 and Figure 9. 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 board to less than 5 nH.

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 MPC5604P microcontroller, 10 µF should be placed between each of the three VDD_LV_CORx/VSS_LV_CORx supply pairs

and also between the VDD_LV_REGCOR/VSS_LV_REGCOR pair. Additionally, 40 μF should be placed between the

VDD_HV_REG/VSS_HV_REG pins.

VDD = 3.0 V to 3.6 V / 4.5 V to 5.5 V, TA = –40 to 125 °C, unless otherwise specified.
