Doc ID 16363 Rev 3

The Vs operating range for this circuit is 5.5 V to 18 V. It is important the respect the input

common mode range specified for the operational amplifiers.

The output voltage V3 can be calculated using the following formula:

The circuit in

Figure 4 provides additional current limitation using an additional PNP

transistor and R6 which allows setting the current limit.

Voltage source with external NPN and current limitation

Figure 5 shows a possible configuration with an NPN pass element using voltage regulator

2 to provide the voltage reference for the regulated output voltage V3. This circuit requires

fewer components compared to the configuration in

Figure 3 but has a limited Vs operating

range (6 V to 18 V).
