I'm trying to put a PStwo (slim ps2) in the car and I would like to avoid the use of an inverter if possible. The PStwo uses an external power supply that provide 8.5V and around 5.3A. I have a few questions as to the feasibility of using linear regulators or something similar to acheive this instead of going the inverter route.
This guy uses a LM138. From what I remember, LM138/338s are good for around 5A. Will there be a problem with the PStwo drawing a little more? Also, if my math is correct, the regulator will need to take care of ~5V. At 5A, this would be 25W of heat? Will a heatsink like this be sufficient or would active cooling be necessary?
Or, would something like this with a LM317 or something instead of the 78XX be better?
If nothing else, this would probably work and for the price, it may not be worth the hassle. Thanks for the help.
