Default Drivers for ml101u29-25

I know I posted a mistake on the subject-but I want to ask: does anyone know of a stable driver for the red laser?

I want to build a 300mw red laser with ml101u29-25 diode-

I have a few options:
-Lm317
-Lm338

But those are all familiar builds and these drivers are very hot..So someone know a driver with a reasonable price but can get high performance -I think a 340ma power is too small for a laser-and someone already knows -please help me

a very very cheap driver that i have tried myself on higher power red that works ok is this one 650nm 532nm 780nm 808nm 980nm Laser Diode LD Drive Driver Current Adjustable | eBay

its adjustable 0-800ma.if you want something with better quality more expensive and faster shipping check DTR https://sites.google.com/site/dtrlpf/home/laser-drivers you can ask him by yourself

Those drivers are made for case positive diodes like 808nm ones. Thus the 532nm and IR in the listing. If you use one with a case negative diode you will short out your batteries. Be very careful when using drivers made for 532nm lasers for anything else.
