REG103GA-5 Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and to prevent overheating.
  • To ensure stable and accurate output voltage, make sure to use a high-quality output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value (e.g., 10uF). Also, ensure the input voltage is stable and within the recommended range.
  • The minimum input voltage required is 2.5V, but it's recommended to keep it above 3V for optimal performance and to ensure the output voltage is within the specified range.
  • The REG103GA-5 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C to ensure reliable operation and prevent overheating. Use a heat sink or thermal pad if necessary.
  • Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Ensure the calculated PD is within the specified maximum power dissipation rating of 1.5W.
