REG1117/2K5 datasheet by Texas Instruments

REG1117/2K5 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the REG1117/2K5?
  The maximum input voltage that can be applied to the REG1117/2K5 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I ensure the output voltage is stable and accurate?
  To ensure the output voltage is stable and accurate, make sure to use a suitable output capacitor (e.g., 10uF) and a minimum load current of 5mA. Also, keep the input voltage ripple low and use a low-ESR output capacitor.
• What is the minimum input voltage required for the REG1117/2K5 to function properly?
  The minimum input voltage required for the REG1117/2K5 to function properly is 7.2V, but it's recommended to keep it above 8V for optimal performance.
• Can I use the REG1117/2K5 in a high-temperature environment?
  The REG1117/2K5 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to use a heat sink or thermal management system to keep the junction temperature below 125°C.
• How do I calculate the power dissipation of the REG1117/2K5?
  The power dissipation of the REG1117/2K5 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.
