TPS3707-33DGN datasheet by Texas Instruments

TPS3707-33DGN Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3707-33DGN?
  The maximum input voltage that can be applied to the TPS3707-33DGN is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the TPS3707-33DGN is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a capacitor with a low equivalent series resistance (ESR) at the output, and avoid using a capacitor with a high capacitance value at the input.
• What is the minimum input capacitance required for the TPS3707-33DGN?
  The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF or 10uF capacitor to ensure stability and low output voltage ripple.
• Can I use the TPS3707-33DGN in a high-temperature environment?
  The TPS3707-33DGN is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
• How do I calculate the output voltage of the TPS3707-33DGN?
  The output voltage of the TPS3707-33DGN is fixed at 3.3V, but it can be adjusted using an external resistor divider network. The output voltage can be calculated using the formula: Vout = 3.3V * (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
