No circuit was drawn or added; the project remains empty.
The requested behavior needs clarification: a two-terminal circuit cannot accept any source voltage and simultaneously reproduce that exact voltage while forcing a fixed output current. A constant-current regulator controls current by changing its output voltage, subject to a compliance range. If you need the output voltage to equal the input voltage under load, current can only be limited, not guaranteed constant.
Practical options are:
- Constant-current sink/load: Draws a set current from a source; useful for source testing.
- Constant-current driver: Supplies a set current to an LED, battery, heater, etc.; output voltage adjusts to the load.
- Current limiter/e-fuse: Passes the source voltage normally and limits current above a threshold.
- Buck-boost CC/CV converter: Regulates both voltage and current within defined input, output, and power ranges.
To define the circuit safely, the required input-voltage range, set current, load type, acceptable voltage drop, and source/sink direction are still needed. Execution stopped because your ACUs ran out.
