Soooo... my professor wants us construct a charger that will output a constant 5v and 1A current no matter the load which I think is impossible considering Ohm's Law right?
so anyway, we tried to make the circuit based from the "Current Limited 6v Charger" from this the data sheet at page 26

We removed the 1 ohm from the circuit. Did we just technically just made the transistor useless?
When we tested the circuit to charge phone, the output current was just at 500mA. Any way to increase the current draw? We're thinking of placing a constant current configuration after the voltage regulator. Will it work and solve our problems?
Thanks!!
EDIT: We replaced the 1.1K ohm with 810 ohm to get around 5.6v Vout
