LP3921SQ/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a thermal pad on the bottom of the package, connected to a copper plane on the PCB to dissipate heat. A minimum of 2oz copper thickness is recommended for the thermal plane.
  • To ensure reliable startup, TI recommends a minimum input voltage of 2.5V, a minimum input capacitance of 1uF, and a maximum input resistance of 1kΩ. Additionally, the EN pin should be pulled high to enable the device.
  • The LP3921SQ/NOPB can deliver up to 2A of output current, but this is dependent on the input voltage, output voltage, and thermal conditions. Refer to the datasheet for detailed current limitations.
  • TI recommends using a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the device from input voltage transients. The TVS diode should be rated for the maximum expected input voltage transient.
  • TI recommends using a low-ESR ceramic capacitor with a value of 1uF to 10uF, depending on the input voltage and output current requirements. X5R or X7R dielectric capacitors are suitable for this application.
