Is there a more powerful analogue of LM338?
I often use the LM317 in my projects, the microcircuit has proven itself well for its ease of connection and functionality. Personally, I like the feature - built-in short circuit protection. Those. a simple power supply stabilized LM317, at the output if two wires are connected, the protection is activated and nothing is heated. But the LM317 has a current limit that can safely drag 1.5A through itself. There is a powerful analogue of the LM350 at 3A and even more powerful LM338 already with a current of 5A. So I'm curious, is there an even more powerful analogue of the LM338, or is this already the limit? Maybe someone knows other microcircuits similar to those. I searched the Internet, from the abundance of information my head is spinning. Maybe someone knows?

Answer 1

KR142EN22A current up to 7 and
if you need more, use varistors - this is protection against short circuit surge surges

Answer 2

Is it not fate to read the datasheet on the LM317? You hang on it an arbitrarily powerful transistor and that's it.

Answer 3

Learn materiel. You write about parametric stabilizers. In fact, this is nothing more than a "smart resistor" which, in combination with the load, forms such a voltage divider that, regardless of the load resistance, a certain voltage will always fall on it. Of course, the extra voltage will go to the stabilizer itself. Therefore, the higher the stabilized current, the higher the dissipated power and, as a result, the larger the dimensions. Those. such stabilizers are used only at low currents. At high currents, pulse stabilizers should be considered, the dissipation power (losses) of which are small. There are a lot of relatively inexpensive stabilizers (including adjustable ones) with a current of up to 15A

Answer 4

It is not recommended to use linear stabilizers for currents above 1.5 amperes. They heat up too much and all the pluses pale before the need to put the fan on the airflow.

Answer 5

In microcircuit sources, there is no limit on the maximum output current (shunt or Hall sensor), as in laboratory sources, there is protection against overheating. The power released into heat by the source is the current per voltage drop. The cheapest solution is a linear source on a powerful transient + a fuse for the required current
