TPS3307-18MJG datasheet by Texas Instruments

TPS3307-18MJG Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3307-18MJG?
  The maximum input voltage that can be applied to the TPS3307-18MJG is 18V, as specified in the datasheet. However, it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent damage to the device.
• Can I use the TPS3307-18MJG in a high-temperature environment?
  The TPS3307-18MJG 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 thermal derating curves.
• How do I ensure the TPS3307-18MJG 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 capacitance on the output. Additionally, avoid using long traces and minimize the loop area of the power lines.
• Can I use the TPS3307-18MJG in a battery-powered device?
  Yes, the TPS3307-18MJG is suitable for battery-powered devices due to its low quiescent current (IQ) of 1.5mA. However, consider the device's shutdown feature to further reduce power consumption when the device is not in use.
• How do I calculate the output voltage of the TPS3307-18MJG?
  The output voltage of the TPS3307-18MJG is adjustable using an external resistor divider network. Use the formula: VOUT = 1.225V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
