TYPICAL APPLICATIONS
SUPPLEMENTAL APPLICATION NOTES
Voltage Regulator
The MC33989 contains two 5 V regulators: The V1
regulator, fully integrated and protected, and the V2 regulator
which operates with an external ballast transistor. This is
illustrated in the following device typical application
schematic.
Figure 21. Device Typical Application Schematic
V1 Regulator
The V1 regulator is 5 V output, 2% accuracy with current
capability of 200 mA max. It requires external decoupling and
stabilizing capacitors. The minimum recommended value
are:
C4: 100 nF
C3: 10

V2 Regulator: Operation with External Ballast Transistor
The V2 regulator is a tracking regulator of the V1 output.
Its accuracy relative to V1 is ±1%. It requires external
decoupling and stabilizing capacitors. The recommended
value are: 22
μ
F esr < 5 ohms, and 47
μ
F esr < 10 ohms.
The V2 pin has two functions: sense input for the V2
regulator and 5 V power supply input to the CAN interface.
Ballast transistor selection: PNP or PMOS transistors can be
used. A resistor between base and emitter (or source and
drain) is necessary to ensure proper operation and optimized
performances. Recommended bipolar transistor is MJD32C.
V2 Regulator: Operation without Ballast Transistor
The external ballast transistor is optional. If the application
does not requires more than the maximum output current
capability of the V1 regulator, then the ballast transistor can
be omitted. The thermal aspects must be analyzed as well.
The electrical connections are shown in
