TPS51117PWR datasheet by Texas Instruments

TPS51117PWR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS51117PWR can handle?
  The TPS51117PWR can handle a maximum input voltage of 6.5V, but it's recommended to keep the input voltage below 5.5V for optimal performance.
• How do I ensure the TPS51117PWR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a high-quality output capacitor with low ESR, and add a 10nF-22nF ceramic capacitor between the VCC and GND pins.
• What is the minimum input capacitance required for the TPS51117PWR?
  The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF-10uF ceramic capacitor to ensure stable operation.
• Can I use the TPS51117PWR in a high-temperature environment?
  The TPS51117PWR is rated for operation up to 85°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
• How do I calculate the output voltage of the TPS51117PWR?
  The output voltage of the TPS51117PWR can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
