TPS3705-33DGN Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS3705-33DGN is 18V, but it's recommended to keep it below 15V for reliable operation.
  • 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 long traces or wires that can cause oscillations.
  • The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF or 10uF capacitor to ensure stable operation.
  • The TPS3705-33DGN is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
  • The output voltage of the TPS3705-33DGN is fixed at 3.3V, but you can adjust it by using an external resistor divider network or by using a different feedback voltage.
