Pros & Cons

Pros

  • ✓ Adjustable 1.2V to 37V output covers most DIY bench-supply voltages
  • ✓ 1.5A output drives small regulated power-supply and charger builds
  • ✓ Onboard current limiting and thermal shutdown protect against faults
  • ✓ TO-220 case bolts to standard heatsinks for higher-current use

Cons

  • ✗ Linear design wastes the input-output difference as heat
  • ✗ Needs a heatsink once load climbs past roughly 0.5A
  • ✗ 1.5A ceiling rules out high-current rail or motor builds
  • ✗ Requires two external resistors to set the output voltage
