TPS3705-50DR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS3705-50DR involves placing the input capacitor close to the VIN pin, using a solid ground plane, and keeping the output capacitor close to the VOUT pin. Additionally, it's recommended to use a separate analog ground plane and to keep the power traces as short and wide as possible.
  • The input capacitor should have a low ESR and be rated for the input voltage. A ceramic capacitor with a value of 1-10uF is a good choice. The output capacitor should also have a low ESR and be rated for the output voltage. A ceramic capacitor with a value of 1-22uF is a good choice. The capacitor values can be adjusted based on the specific application requirements.
  • The maximum ambient temperature range for the TPS3705-50DR is -40°C to 125°C. However, the device can operate at a junction temperature of up to 150°C.
  • The output voltage of the TPS3705-50DR can be calculated using the following formula: VOUT = 0.5 x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is 0.9V to 5.5V.
  • The quiescent current of the TPS3705-50DR is typically around 20uA, but it can be as low as 10uA in shutdown mode.
