Electronic – How to get more amps from a voltage regulator


I'm a noob that is just getting started.

I'm using an LM317T to generate 6V but I need a little more amperage. Can I just double my LM317T and resistors configuration and put them in parallel?

Ignore the resistor.

TI's datasheet shows to ways to increase the current output of a 317. The first one is basically what you're suggesting:

Notice the 0.2 Ohm resistors at each output. These allow for differences in the reference voltage between the 317 chips.

The second one uses external transistors instead of paralleling 317's:

This concept can also be done with a single external transistor as shown here:
