LP5951MF-1.3/NOPB Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to the bottom layer to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended.

  • Ensure that the device is operated within the recommended junction temperature (TJ) range of -40°C to 125°C. Use a heat sink or thermal interface material to reduce thermal resistance. Also, consider derating the output current and voltage to prevent overheating.

  • A low-ESR ceramic capacitor (X5R or X7R dielectric) with a value of 10 μF to 22 μF is recommended for input decoupling. This helps to filter out noise and ensure stable operation.

  • Yes, the LP5951MF-1.3/NOPB is qualified for automotive and high-reliability applications. It meets the requirements of AEC-Q100 and is manufactured using a robust process to ensure high reliability and low defect rates.

  • Use a scope to monitor the input and output voltages, as well as the current drawn from the input. Check for proper PCB layout, decoupling, and thermal management. Consult the datasheet and application notes for troubleshooting guidelines and common pitfalls to avoid.
