The Belleson Superpower, the ultimate voltage regulator ... ?

[BMW850]

Hi all,

These are beautiful words but this is all true what it says on the site of Belleson?
Now we have no longer to look at other brands, or is this all marketing strategy ... or are they real good what it say on the site!

The Belleson Superpower, the ultimate voltage regulator

· Superpower compared to a Battery
· Superpower compared to a Jung style super regulator
· Superpower compared to LM317
· Superpower compared to LM7812
· Superpower compared to Dexa NewClassD
· Superpower compared to Burson

The Belleson Superpower regulator, like Mr. Jung's design, uses the regulator's cleaned and quieted output voltage as the "bootstrapped" power source for its own internal reference and error amplifier. In addition,
· It is stable with the included 10µF output capacitance and remains stable with larger values.
· Output voltage is set with a single resistor.
· Superpower fits a 3 terminal regulator footprint and can bolt directly to a heat sink.
· Start-up is guaranteed—the expected output voltage is the only stable state.
· Gain/bandwidth of the internal amplifier is independent of output voltage.
· Drop-out voltage is as low as ½V at low current, less than 2V at currents to ½A for standard or 1A+ for the HV and J versions.
· Superpower performs better without a pre-regulator.
· There are no zener diodes.

Neat, but not cheap!

What's more interesting is the measurements of the other boutique power supplies.

I'm not convinced that this regulator is so wonderful. Its noise is specified at 28uVrms, higher than the LM317 value of 22uVrms and far higher than, say, a TeddyReg.

In the transient comparison with the LM317, no mention is made of the exact LM317 feedback configuration ("as in datasheet" could mean anything). And for the 1A transient a larger-than-standard output device is used! How about we just put multiple LM317s in parallel?

Overall, I anyhow think that the LM317 is very hard to beat, especially considering the price. I can get one from my local electronic parts shop around the corner for 1.25 Euros. For the money of a Belleson, you can put a lot of those in cascade and in parallel!

There's too much missing from any of the comparisons, and the datasheet, to form any real opinion.

It's unfortunate that Belleson doesn't feel comfortable enough to provide at least a simplified schematic so that potential buyers can better assess the novelty of their regulator design.

They can be much cheaper than 1,25€/pcs. 5,35€/20 pcs, delivered to your home adress. Original parts, not fake.
For 5€ you can buy decent opamp, pass transistor & LED's for voltage reference and make your own regulator, much better than '317.

For small quantity & DIY purposes, price is almost irrelevant. You want performance, not cheap BOM.

LM317 is not hard to beat. A decent shunt reg will leave it in the dust. Implement the simple Salas v1.0 and then smile at the Belleson SUPERDUPER. DIY at its best. Mr. stormsonic knows what he's talking about, because he implemented quite a few regs

Tomorrow I'll run the LR and Z test on the Belleson.

Except if it does not fit into the available space.

For a rather high price there are some compact integrated regs available, but your 15-component custom regulator will be bulky and a good reason to learn the art of casemodding.

BTW, I have near-to-no experience in custom shunt regulators; what output voltage noise is achievable for 100uA of bias current? (far lower than 22uV rms, I hope...)
