TL are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for TL description/ordering information. The TL is an adjustable three-terminal high- voltage regulator with an output range of. V to V and a DMOS output. TL regulator is one of the favorite regulators I like apart from the usual LM family members. This fits into our topic of today – inexpensive, small size.

Oct 17, 1. Tom Carpenter 37k 2 65 It was fun, but I’m afraid you’re right. This setup is overkill for my Wh pack, but I wanted something that’d be easy to scale up for whatever EV project I build.

This circuit should work, but it is untested. Do you have another question? Linear regulators work by varying the resistance of a pass transistor, turning any excess voltage in to heat. Quote of the day. It is simple, fool proof, small in size, inexpensive and works well! Tll783 capacitance can be reduced significantly compared to not using any active voltage regulation.

Turning the potentiometer would get us the voltage needed. Ron, thank you very much for the answer.

A very simple one at that!


Have you checked all of the solder joints for shorts? My last post is tp783 because I included a link I guess. Go to Support forums. We are glad that we were able to resolve this issue, and will now proceed to close this thread.

You need most of an ohm in each emitter circuit to make them behave properly because their Vbe will not match and the best transistor will go into thermal runaway as it heats up and becomes even more conductive.

DC power supply 12V 2A Posted by xxxyyyba in forum: If NPN are better try current helper seen in figure The main disadvantage would probably be in electrical noise on the output due to the switching converter. I guess I tl738 up on this plan. Basically I just want an easy way to get 80vv.


The tl is a linear regulator and can handle that. Still not sure how I’m going to achieve this. With a V input, you get 52V across the t783 16mA, which gives 0. Oct 17, 3.

Oct 17, 2. Post as a guest Name. This way I could use a much smaller transformer but still retain the safety benefits of a having a transformer. Due to the low noise and ripple requirements for the above fl783 2 applications, not to mention the current capability, using TL is not such a bad choice after all.
