REG101NA-3.3/3K Frequently Asked Questions (FAQs)

  • The maximum input voltage is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
  • To ensure a stable output voltage, make sure to use a suitable input capacitor (e.g., 1uF ceramic) and a minimum output capacitor (e.g., 2.2uF ceramic) as close to the regulator as possible.
  • The dropout voltage is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage (e.g., 4.8V for a 3.3V output).
  • The REG101NA-3.3/3K is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure proper heat sinking and thermal management to maintain reliability.
  • Power dissipation (PD) can be calculated as PD = (VIN - VOUT) x IOUT, where VIN is the input voltage, VOUT is the output voltage, and IOUT is the output current.
