TPS51125ARGET Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, with an ESR of 0.1 ohms or less, to ensure stability and reduce input voltage ripple.
  • The output voltage can be set using the FB pin and an external resistor divider network. The recommended resistor values are R1 = 10kohm and R2 = 2.2kohm for a 1.8V output, but these values can be adjusted based on the desired output voltage and application requirements.
  • The maximum input voltage is 6.5V, but it's recommended to operate the device within the specified input voltage range of 2.7V to 5.5V for optimal performance and reliability.
  • The device has a thermal shutdown feature that turns off the output when the junction temperature exceeds 150°C. Ensure good thermal design practices, such as providing adequate heat sinking and airflow, to keep the device within its operating temperature range of -40°C to 125°C.
  • Follow good PCB design practices, such as separating the input and output stages, using a solid ground plane, and minimizing trace lengths and loops. Place the input capacitor close to the VIN pin and the output capacitor close to the VOUT pin to reduce noise and EMI.
