LP3952RL/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the device to improve thermal performance. A minimum of 2 oz copper thickness is recommended for the thermal pad.
  • To ensure reliable startup and shutdown, it is recommended to add a 10nF capacitor between the EN pin and GND, and a 1kΩ resistor between the EN pin and VIN. This helps to filter out noise and ensure a clean enable signal.
  • Although the datasheet specifies a maximum input voltage of 15V, it is recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the device.
  • To optimize output voltage accuracy, it is recommended to use a high-precision external resistor divider network to set the output voltage, and to minimize the resistance of the output voltage sense lines to reduce voltage drops.
  • Texas Instruments recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, and a voltage rating of at least 16V, to filter out input noise and ensure stable operation.
