Voltage Regulator Electrical Characteristics
The internal voltage regulator requires an external NPN (BCP56 or BCP68) ballast to be connected as shown in Figure 4 as well
as an external capacitance (CREG) to be connected to the device in order to provide a stable low voltage digital supply.
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.
For the MPC5604P microcontroller , 10 F 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.

2 A device will be defined as a failure if after exposure to ESD pulses the device no longer meets the device
specification requirements. Complete DC parametric and functional testing shall be performed per applicable
device specification at room temperature followed by hot temperature, unless specified otherwise in the device
specification
