TPS3305-18DR Frequently Asked Questions (FAQs)

  • The TPS3305-18DR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
  • To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10uF ceramic capacitor between the VIN and GND pins.
  • The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF or 10uF ceramic capacitor to ensure stability and optimal performance.
  • The TPS3305-18DR is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliability and prevent overheating.
  • The output voltage of the TPS3305-18DR is adjustable and can be calculated using the formula: VOUT = 1.235V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
