TPS3306-15DGK datasheet by Texas Instruments

TPS3306-15DGK Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3306-15DGK?
  The maximum input voltage that can be applied to the TPS3306-15DGK is 15V, as specified in the datasheet. However, it's recommended to keep the input voltage below 12V to ensure reliable operation and to prevent overheating.
• How do I choose the correct output capacitor for the TPS3306-15DGK?
  The output capacitor should be chosen based on the desired output voltage ripple and transient response. A general rule of thumb is to use a capacitor with a value of at least 10uF and a voltage rating of at least 1.5 times the output voltage. For example, for a 3.3V output, a 10uF capacitor with a 5V or higher voltage rating would be suitable.
• What is the minimum input capacitance required for the TPS3306-15DGK?
  The minimum input capacitance required for the TPS3306-15DGK is 1uF, as specified in the datasheet. However, it's recommended to use a higher value capacitor, such as 4.7uF or 10uF, to ensure stable operation and to filter out input voltage noise.
• Can I use the TPS3306-15DGK in a high-temperature environment?
  The TPS3306-15DGK is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliable operation. Consult the datasheet for thermal derating information.
• How do I ensure the TPS3306-15DGK is stable and doesn't oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, keep the input and output capacitors close to the device, and use a low-ESR output capacitor. Additionally, avoid using long traces and minimize the distance between the device and the capacitors.
