TPS60500DGSR datasheet by Texas Instruments

TPS60500DGSR Frequently Asked Questions (FAQs)

• What is the recommended layout for the TPS60500DGSR to minimize noise and ensure stability?
  A good layout practice is to keep the input and output capacitors close to the device, and to use a solid ground plane to reduce noise. Additionally, it is recommended to keep the feedback resistors close to the device and to use a separate analog ground plane to reduce noise coupling.
• How do I choose the right output capacitor for the TPS60500DGSR?
  The output capacitor should be chosen based on the output voltage and current requirements. A general rule of thumb is to use a capacitor with a capacitance value of at least 10uF and a voltage rating of at least 1.5 times the output voltage. Additionally, the capacitor's ESR (Equivalent Series Resistance) should be low enough to ensure stability.
• What is the maximum input voltage that the TPS60500DGSR can handle?
  The maximum input voltage that the TPS60500DGSR can handle is 5.5V. Exceeding this voltage may cause damage to the device.
• How do I adjust the output voltage of the TPS60500DGSR?
  The output voltage of the TPS60500DGSR can be adjusted by changing the ratio of the feedback resistors (R1 and R2). The output voltage is calculated using the formula: Vout = 1.2V x (1 + R2/R1).
• What is the typical startup time of the TPS60500DGSR?
  The typical startup time of the TPS60500DGSR is around 10ms. However, this time can vary depending on the input voltage, output voltage, and output capacitor value.
