TPS7133QD datasheet by Texas Instruments

TPS7133QD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS7133QD?
  The maximum input voltage that can be applied to the TPS7133QD is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure stability and prevent oscillations in the TPS7133QD?
  To ensure stability and prevent oscillations, it's essential to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 2.2uF), and add a 10nF capacitor between the EN and GND pins.
• What is the minimum input voltage required for the TPS7133QD to operate?
  The minimum input voltage required for the TPS7133QD to operate is 2.7V, but it's recommended to keep it above 3V for optimal performance.
• Can I use the TPS7133QD in a high-temperature environment?
  The TPS7133QD is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure proper heat dissipation to prevent overheating.
• How do I calculate the output voltage of the TPS7133QD?
  The output voltage of the TPS7133QD can be calculated using the formula: Vout = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
