REG104FA-3.3/500 datasheet by Texas Instruments

REG104FA-3.3/500 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the REG104FA-3.3/500?
  The maximum input voltage is 12V, but it's recommended to keep it below 10V to ensure stable operation and minimize power dissipation.
• How do I ensure the output voltage is stable and accurate?
  To ensure a 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, keep the input voltage within the recommended range and minimize noise on the input lines.
• What is the minimum input capacitance required for stable operation?
  The minimum input capacitance required is 1uF, but it's recommended to use a higher value (e.g., 4.7uF) to ensure stable operation and minimize input voltage ripple.
• Can I use the REG104FA-3.3/500 in a high-temperature environment?
  The REG104FA-3.3/500 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to ensure reliable operation at high temperatures. Consult the datasheet for thermal derating guidelines.
• How do I calculate the power dissipation of the REG104FA-3.3/500?
  The power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT, where VIN is the input voltage, VOUT is the output voltage, and IOUT is the output current. Make sure to consider the thermal resistance (RθJA) and the maximum junction temperature (TJ) to ensure safe operation.
