Printed at 03:39pm 29th March 2024 LM317 Current CalculatorA handy online output current calculator for the LM317, LM338, and other linear voltage regulatorsIn our article Using the LM317 with LED Lighting (1) we looked at how the LM317T (2) (and high current equivalent LM338T (3)) can be used to supply a fixed current to a load - in the case of the article to LED bulbs.
Do not forget that the maximum continuous current which can be managed by the LM317T is 1.5 Amps, and that is with a decent heatsink (5) fitted (click here to see our article LM317T Heatsinking (6) for more details). The LM338T is rated at 5 Amps of continuous current with 50ms bursts of up to 7 Amps. However with a large heatsink and/or cooling fan it can manage continuous currents of 8 Amps+.

We also have a guide to making an Adjustable Voltage LM317 Power Supply (8) here.Web Link References(1) http://www.reuk.co.uk/Using-The-LM317T-With-LED-Lighting.htm(2) http://www.reuk.co.uk/LM317T-Voltage-Regulator-Chip.htm (3) http://www.reuk.co.uk/buy-LM338T.htm (4) http://www.reuk.co.uk/Resistor-Colour-Codes.htm (5) http://www.reuk.co.uk/buy-TO220-BOLT-ON-HEATSINK.htm (6) http://www.reuk.co.uk/LM317T-Heatsinking.htm (7) http://www.reuk.co.uk/LM317-Voltage-Calculator.htm (8) http://www.reuk.co.uk/LM317-Adjustable-Power-Supply.htm Article from REUK.co.uk: http://www.reuk.co.uk/LM317-Current-Calculator.htm Published: 24th September 2014 © REUK 2024 |
