About 5V, 500mA coming out of R_load now. At this time, when I gradually reduce the R_load, the voltage and current increase. In this situation, I need to limit R_load to 5V,500ma, what should I do?

As I previously stated, and showed in my circuit, you need to put the currentlimit circuit before (to the left of) the voltage regulating circuit.is there a better way
What exactly are you trying to achive? To answer your question: You could use five 2 Ohm resistors in series or five 2 Ohm resistors in series, one 10 Ohm resistor or two 20 ohm resistors in parallel. It all depends on what you have available.is there a better way than just connecting 10*(1 ohm) resistors?
About 5V, 500mA coming out of R_load now. At this time, when I gradually reduce the R_load, the voltage and current increase. In this situation, limit R_load to 5V,500ma. So with R_5 taking 2.5w and using only 0.25w of resistance, is there a better way than just connecting 10*(1 ohm) resistors?
Putting equal value resistors in series or parallel to get the desired resistance will divide up by power by the number of resistors.Is there a better way to divide 2.5w by connecting resistors
