Insufficient Power on my Load

[DarkArrow29]

Hi! I have this simple circuit that activates a load, whenever the switch is pressed (shorted). When the switch is released from being pressed, the load will power down slowly. I have already put this up on a breadboard. When the load is an LED, it works! But the actual load that I will use is a 2W MP3 Decoder. The load only receives 17.4 mW (based on my schematic diagram below) but before reaching the LM317, the power is 4.11 W. How can I make the load receive at least 2W. Please help! Thank you!

this circuit is not working like that. The switch activated transistors are a mess; either, what i recommend, switch the LM317 directly with a hardware switch, or you use a  single pnp transistor switching the base with a resistor to ground, emitter to the plus terminal of the supply - but that has to be a higher power model than a BC558; e.g. a BD140 - but that's all pretty silly for the purpose - use a switch - that's it.

And use 120 ohms for R5 and change R2 accordingly.

Just made a big change, sorry. So my new simulation makes the LED light up at 4.17V. If I will replace the LED with an MP3 Decoder Module with 2W and 3.7 to 5V requirement, how can this circuit activate the said module?

Why do you use the same silly setup again now? I told you, it's not correct like that.

The pnp transistor has to be with the emitter on the plus rail; the load on the collector, the base with a resistor and switch to ground; the npn transistor is obsolete
