TPS3809K33DBVR Frequently Asked Questions (FAQ)

  • The recommended layout and placement for the TPS3809K33DBVR involves placing the device close to the power source, using a solid ground plane, and keeping the input and output capacitors close to the device. Additionally, it is recommended to use a low-ESR capacitor for the output capacitor and to minimize the loop area of the input and output traces.

  • The choice of input and output capacitors for the TPS3809K33DBVR depends on the specific application requirements. In general, a low-ESR capacitor with a value of 10uF to 22uF is recommended for the output capacitor, while a ceramic capacitor with a value of 1uF to 10uF is recommended for the input capacitor.

  • The maximum input voltage that the TPS3809K33DBVR can handle is 18V. Exceeding this voltage may cause damage to the device.

  • The output voltage of the TPS3809K33DBVR can be adjusted by using a resistive divider network between the output pin and the ground pin. The output voltage can be calculated using the formula: Vout = 1.22V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.

  • The thermal shutdown temperature of the TPS3809K33DBVR is 150°C. If the device temperature exceeds this value, it will shut down to prevent damage.
