TPS3307-25DGNRG4 datasheet by Texas Instruments

TPS3307-25DGNRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3307-25DGNRG4?
  The maximum input voltage that can be applied to the TPS3307-25DGNRG4 is 6.5V, as specified in the datasheet. However, it's recommended to keep the input voltage below 6V to ensure reliable operation and to prevent damage to the device.
• Can I use the TPS3307-25DGNRG4 in a high-temperature environment?
  The TPS3307-25DGNRG4 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage as the temperature increases to prevent overheating and ensure reliable operation. Consult the datasheet for more information on thermal derating.
• How do I ensure the TPS3307-25DGNRG4 is stable and doesn't oscillate?
  To ensure stability, follow the layout guidelines in the datasheet, keep the input and output capacitors close to the device, and use a minimum of 10uF ceramic capacitor at the output. Additionally, avoid using long traces and minimize the loop area of the power lines to prevent oscillation.
• Can I use the TPS3307-25DGNRG4 in a low-power mode to reduce power consumption?
  Yes, the TPS3307-25DGNRG4 has a shutdown pin that can be used to put the device in a low-power mode. When the shutdown pin is pulled low, the device enters a low-power state, reducing the quiescent current to less than 1uA. Consult the datasheet for more information on shutdown mode.
• How do I calculate the output voltage of the TPS3307-25DGNRG4?
  The output voltage of the TPS3307-25DGNRG4 is set by the resistor divider network connected to the FB pin. The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network. Consult the datasheet for more information on output voltage setting.
