Hello, I recently bought a Tamiya 70097 gearbox and I'm trying to build a small line following robot. As a driver for the motors I used a L298. The motors are rated at max. 3V.
I am using an LM317T to power the motors at 3V and it's working fine, except for the fact that the LM317T gets extremely hot even with a small heatsink on it(can't keep my fingers on it!!). The L298 has a bigger heatsink and it's fine.
As a power source I am using 6 AAA (1.5V) batteries connected to the LM317T and then to the L298's motor Vin.
Is there a way to increase the maximum 1,5 A limit of the LM317T or is there another voltage regulator IC that delivers more than 1.5A ? Should I use a MOSFET? If yes, how ? I never used MOSFETs before.
