Voltage Regulator Electrical Characteristics

The internal voltage regulator requires an external NPN (BCP56 or BCP68) ballast to be connected as shown in Figure 5 as well

as an external capacitance (CREG) to be connected to the device in order to provide a stable low voltage digital supply to the

device. 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 15 nH.

For the MPC5606S microcontroller , 10 µF should be placed between each of the three VDD12/VSS12 supply pairs and also

between the VDDPLL/VSSPLL pair. Additionally, 200 μF should be placed between the VDDR pin and the adjacent VSS pin.

VDDR = 3.0 V to 3.6 V / 4.5 V to 5.5 V, TA = -40 to 105 °C, unless otherwise specified.
