TPS79533DCQG4 datasheet by Texas Instruments

TPS79533DCQG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79533DCQG4?
  The maximum input voltage is 5.5V, as specified in the datasheet. Applying a voltage higher than this can damage the device.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to use the recommended output capacitor value and type, as specified in the datasheet. Additionally, the input capacitor should be placed close to the VIN pin to minimize noise and ensure stability.
• What is the minimum input voltage required for the TPS79533DCQG4 to operate?
  The minimum input voltage required is 2.7V. Operating the device below this voltage may result in unstable output or failure to regulate the output voltage.
• Can I use the TPS79533DCQG4 in a high-temperature environment?
  The TPS79533DCQG4 is rated for operation up to 125°C. However, it's essential to consider the thermal design and ensure that the device is properly heat-sinked to prevent overheating.
• How do I calculate the output voltage of the TPS79533DCQG4?
  The output voltage can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network. The output voltage range is 0.8V to 3.3V.
