Design Tips
- Use input & output capacitors (0.33µF & 0.1µF) close to the regulator pins for stability.
- Add a heatsink when drawing currents near 1.5A to avoid thermal shutdown.
- Ensure input voltage headroom (~2V above output) for proper regulation.
- Avoid reverse polarity by adding a protection diode at the output or input.
