Superpower regulator and Bel amp Components Warranty
Due to the fraught nature of circuit development, Belleson LLC cannot be liable for loss or damage to regulator or op amp components or their associated circuitry. Thus these components have no expressed or implied warranty. We work with you, our customers, as best we can to prevent problems. Please contact us with any questions or concerns prior to applying power to your circuit.
Important Legal Information
By using Belleson Superpower regulators, you agree that SPLV, SPHV, SPX, SPHP have no output protection, and a short circuit of the output to ground can damage or destroy the regulator. Also, these regulators have power dissipation limits as described in their respective datasheets, and exceeding those limits may result in damage or destruction of the device and potential damage to connected circuitry or equipment. All devices are tested prior to shipment and damaged devices will not be replaced. Belleson is not responsible for ancillary damage to associated connected components or equipment, nor liable for any related loss(es).
By using Belleson Bel amps op amps, you agree that components can be damaged by accident, misapplication or by exceeding operating or use limits.
You also agree that misuse or misapplication of Belleson products may cause damage where attempted use or application occurs, and you, as user of the product(s), or a company or corporation using the product(s), accept all responsibility for all consequences of use or application of Belleson product(s) and will not hold Belleson responsible for any damage nor injury as a result of use or attempted use of Belleson products. Belleson also is not responsible for damage to, or replacement of, equipment or components connected to or powered by Belleson products.
Belleson products are not authorized for use as critical components in life support devices or systems.
As used herein:
1. Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or (b) support or sustain life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.
2. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.

NOTE! This calculator only applies to a linear transformer+rectifier+filter cap power source. It is not accurate if the raw source is a SMPS.
Use this calculator to select a suitable heat sink for your Superpower regulator. The Max Heat Sink value is the highest thermal resistance allowed for the given conditions. The bigger the thermal resistance, the smaller the heat sink.
Calculator fields have only minimum validation so if the Vrms result has something bizarre (like "NaN"), recheck your input values. If Vin is negative, Vout must also be negative, otherwise the calculations are incorrect.
Heat Sink
The value in the Max heat sink °C/W box shows the maximum thermal resistance for a heat sink on a Superpower with the given Vin. The heat sink calculation assumes a 75°C temperature increase of the regulator.
Assumptions
- Input voltage is DC or DC equivalent in Vrms
- Select SP for current < 500mA, SPJ or SPL for higher currents
- Calculator only works to 3A
- Heat sink allows 75°C temperature rise due to power dissipation
Can this calculator be used for any voltage regulator?
It can be used for any series voltage regulator if you know the drop-out voltage. For Superpower Type choose Custom regulator and enter the drop-out value for your regulator at the given load current.
SPLV79 1A Superpower Regulators, a low voltage high current regulator using a variation of our patented Belleson super regulator design.
- Pinout matches LM337 and LM79xx type monolithic regulators.
- 1A output current
- Choose from 1.1V, 1.2V, 1.5V, 1.8V, 2.0V, 2.5V output
- 2.4V drop out at 1A
- 110dB ripple rejection at power line frequency
- 5µV total RMS noise, 20Hz-20kHz
- <10µsec recovery time for a 1A current step
- Positive and negative versions
As a fixed output regulator, this requires minor modifications when replacing an adjustable regulator such as LM337.
