TL28L92IFR datasheet by Texas Instruments

TL28L92IFR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise and coupling.
• How do I ensure stability and prevent oscillations?
  Ensure the output capacitor is properly sized and placed close to the output pin. Also, add a 10nF-100nF capacitor between the VIN and GND pins to filter out noise.
• What is the maximum input voltage I can use with this regulator?
  The TL28L92IFR can handle input voltages up to 28V, but it's recommended to keep the input voltage below 24V for optimal performance and reliability.
• Can I use this regulator in a high-temperature environment?
  The TL28L92IFR is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
• How do I calculate the output voltage accuracy and tolerance?
  The output voltage accuracy is typically ±2% over the operating temperature range. Calculate the output voltage tolerance by adding the initial tolerance (±2%) to the temperature coefficient (±0.5%/V).
