TPS51116PWPR datasheet by Texas Instruments

TPS51116PWPR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS51116PWPR?
  The maximum input voltage that can be applied to the TPS51116PWPR is 6.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
• How do I ensure the TPS51116PWPR is stable and does not oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a 10nF ceramic capacitor between the VCC and GND pins. Additionally, ensure the input voltage is within the recommended range.
• What is the minimum input capacitance required for the TPS51116PWPR?
  The minimum input capacitance required is 10uF, as specified in the datasheet. Using a capacitor with a value lower than this may affect the regulator's stability.
• Can I use the TPS51116PWPR in a high-temperature environment?
  The TPS51116PWPR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Ensure the device is properly heatsinked and follow the thermal design guidelines in the datasheet.
• How do I calculate the output voltage of the TPS51116PWPR?
  The output voltage of the TPS51116PWPR is adjustable and can be calculated using the formula: Vout = (R1 / R2) * 0.8V + 0.8V, where R1 and R2 are the resistors connected to the FB pin.
