TPS73133DBVRG4 datasheet by Texas Instruments

TPS73133DBVRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS73133DBVRG4?
  The maximum input voltage that can be applied to the TPS73133DBVRG4 is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent damage to the device.
• How do I ensure stability and prevent oscillations in the TPS73133DBVRG4?
  To ensure stability and prevent oscillations, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor in the TPS73133DBVRG4?
  The minimum ESR required for the output capacitor is 0.1 ohms, but it's recommended to use a capacitor with an ESR of 0.05 ohms or less to ensure stability and optimal performance.
• Can I use the TPS73133DBVRG4 in a high-temperature environment?
  The TPS73133DBVRG4 is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the device is properly heat-sinked to prevent overheating and ensure reliable operation.
• How do I calculate the output voltage of the TPS73133DBVRG4?
  The output voltage of the TPS73133DBVRG4 can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.24V), R1 is the resistance between the output and the feedback pin, and R2 is the resistance between the feedback pin and ground.
