REG104GA-3.3G4 datasheet by Texas Instruments

REG104GA-3.3G4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the REG104GA-3.3G4 can handle?
  The maximum input voltage is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure the output voltage is stable and accurate?
  To ensure a stable output voltage, make sure to use a suitable input capacitor (e.g., 10uF) and output capacitor (e.g., 10uF to 22uF) as close to the regulator as possible. Also, keep the input voltage within the recommended range.
• What is the dropout voltage of the REG104GA-3.3G4?
  The dropout voltage is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage (3.3V) for proper regulation.
• Can I use the REG104GA-3.3G4 in a high-temperature environment?
  The REG104GA-3.3G4 is rated for operation up to 125°C, but it's essential to ensure proper heat sinking and thermal management to prevent overheating. Consult the datasheet for thermal resistance and power dissipation guidelines.
• How do I calculate the power dissipation of the REG104GA-3.3G4?
  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 check the datasheet for the maximum allowed power dissipation.
