TPS3307-25DR datasheet by Texas Instruments

TPS3307-25DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3307-25DR?
  The maximum input voltage that can be applied to the TPS3307-25DR is 5.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
• How do I ensure the TPS3307-25DR 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-100nF ceramic capacitor between the VIN and GND pins to filter out noise.
• What is the minimum input capacitance required for the TPS3307-25DR?
  The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF-10uF ceramic capacitor to ensure stability and low input impedance.
• Can I use the TPS3307-25DR in a high-temperature environment?
  The TPS3307-25DR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure proper thermal design and consider derating the output current at high temperatures.
• How do I calculate the output voltage of the TPS3307-25DR?
  The output voltage is set by the resistor divider network between the FB pin and GND. Use the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
