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.

TL783 Regulator

Oct 17, 1. I understand and accept the privacy policy. What do you think of this post? Linear regulators work by t,783 the resistance of a pass transistor, turning any excess voltage in to heat. Oct 18, 7.

The preceding stage to the voltage regulator could be tube or solid rectified; choke input or cap input; bridge or full wave rectified; and etc.

I’m assembling a power supply kit from one of the DIY kit retailers. In reply to Ron Michallick: Upload Pictures or Graphics optional [? If you have a related question, please click tl873 ” Ask a related question ” button in the top right corner. It should be clear I have no clue what I’m doing I thought this would be as easy as making a 5v regulator, but I guess not.

Go to Support forums. I’ll figure out the math tomorrow and try to find a suitable transistor. PDF THermal resistance junction tl7833 case is 1. Discussion in ‘ General Electronics Chat ‘ started by auraslipOct 17, There are ways to use TRIACs a type of thyristor as a pre-regulator to get the voltage on the filter cap within range of a linear regulator; I don’t happen to have a schematic for one at the voltage you’re talking about.


Others use the variable lab supplies mention to for voltage and current control. Sign up using Email and Password. In your tl73, you could implement a switch-mode converter instead of linear regulation.

82v 2a-3a power supply using tl | All About Circuits

Is the tl738 easy way of current boost to 3A with external transistors or maybe paralleling? Jan, This circuit should work, but it is untested. Find out what artists are using to create phenomenal modern pieces. A very simple one at that! Due to the low noise and ripple requirements for the above first 2 applications, not to mention the current capability, using TL is not such a bad choice after tk783.

Here is a current limited, voltage adjustable power supply I made in LTspice.

The maximum voltage limit of Vdc for the TL is not considered very high and we have to select the tubes that could work well and sound good under such conditions. Basically I just want an easy way to get 80vv. TI, its suppliers and providers of content t,783 the right to make corrections, deletions, modifications, enhancements, improvements and other changes to the content and materials, its products, programs and services at ttl783 time or to move or discontinue any content, products, programs, or services without notice.


Where were you going to get the V DC from?

82v 2a-3a power supply using tl783

Feb 28, 1: To have the smallest size possible, use solid stage rectifiers and replace the choke with a resistor. With V in, 80v out, and a 3A load, Q2 will dissipate 2.

If the board has minimal cooling, 0. The proper way to do this is to get a transformer that will give you the right voltage after rectification.

You can substitute the potentiometer with a fixed resistor if you want. Do you have the same thoughts? So even with no off-board load connected, your regulator will be dissipating a chunk of energy simply because that is how it regulates. That reminds me of the ECC86 that is even better suited as it is meant to work with batteries! Parallel PNP are possible with emitter degeneration resistors. Mar 1, 2: Customer is fully responsible for all design decisions and engineering with regard to its products, including decisions relating to application of TI products.

Have you checked the resistor values of R1 and R2 are correct? We are glad that we were able to resolve this issue, and will now proceed to close this thread.
