AL1791AFE-13 Frequently Asked Questions (FAQs)

  • A thermal pad is recommended under the IC to improve heat dissipation. A 2-layer or 4-layer PCB with a solid ground plane is also recommended to reduce thermal resistance.
  • Ensure that the input voltage is within the recommended range, and that the output capacitor is of sufficient value and type (e.g. X5R or X7R ceramic) to maintain stability.
  • The maximum ambient temperature for reliable operation is 85°C, but derating is recommended for temperatures above 70°C to ensure long-term reliability.
  • Yes, but ensure that the input voltage is sufficient to support the required output current, and that the thermal design is adequate to dissipate the heat generated.
  • Use a TVS diode or a transient voltage suppressor (TVS) in parallel with the input capacitor to protect the regulator from input voltage transients.
