2.1.2

Voltage regulator: V2

The voltage regulator V2 can supply additional 5 V loads (e.g. logic components or the

integrated HS CAN transceiver or external loads such as sensors or potentiometers). The

maximum continuous load current is 100 mA. The regulator is protected against:

●

Overload

●

Overtemperature

●

Short circuit (short to ground and battery supply voltage)

●

Reverse biasing

2.1.3

Increased output current capability for voltage regulator V2

For applications which require high output currents, the output current capability of the

regulator can be increased my means of the integrated operational amplifiers and an

external pass transistor.

Voltage source with external PNP and current limitation

Figure 3 shows a possible configuration with a PNP pass element using voltage regulator 2

to provide the voltage reference for the regulated output voltage V3.
