Linear Regulator Calculator
Calculate linear voltage regulator heat dissipation, junction temperature, efficiency, and heatsink requirements. Determine if your regulator needs a heatsink and what thermal resistance is required.
How to Use Linear Regulator Calculator
Enter input voltage, output voltage, and load current. Optionally add thermal resistance values for junction-to-case, case-to-sink, and sink-to-ambient to get full thermal analysis with heatsink recommendations.
Step-by-Step Instructions
- Enter input and output voltages
- Enter load current in milliamps
- Optionally enter thermal resistance values
- Click Calculate to see heat dissipation and thermal status
