TPS3307-18DG4 datasheet by Texas Instruments

TPS3307-18DG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3307-18DG4?
  The maximum input voltage that can be applied to the TPS3307-18DG4 is 18V, as specified in the datasheet. However, it's recommended to operate the device within the recommended operating conditions to ensure reliable operation.
• How do I ensure the TPS3307-18DG4 is stable and doesn't oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR capacitor for the output filter, and avoid using a capacitor with high equivalent series resistance (ESR) for the input filter. Additionally, ensure that the input voltage is within the recommended operating range.
• What is the minimum input capacitance required for the TPS3307-18DG4?
  The minimum input capacitance required for the TPS3307-18DG4 is 1uF, as specified in the datasheet. However, it's recommended to use a higher capacitance value, such as 4.7uF or 10uF, to ensure stable operation and reduce input voltage ripple.
• Can I use the TPS3307-18DG4 in a high-temperature environment?
  The TPS3307-18DG4 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the device's output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the output voltage of the TPS3307-18DG4?
  The output voltage of the TPS3307-18DG4 is adjustable using the feedback resistors R1 and R2. The output voltage can be calculated using the formula: Vout = 1.225V x (1 + R2/R1).
