LMP2231BMAE/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer to improve thermal performance. Additionally, it's recommended to use a thermal pad on the underside of the package to connect to the ground plane.
  • To ensure stability in the output voltage, it's recommended to use a minimum output capacitance of 10uF with an ESR of less than 1 ohm. Additionally, the output voltage should be decoupled from the input voltage using a 1uF capacitor.
  • Although the datasheet specifies a maximum input voltage of 15V, it's recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the device.
  • The LMP2231BMAE/NOPB has an internal overcurrent protection (OCP) feature that limits the output current to 1.5A. However, it's recommended to add an external current limiting resistor or fuse to protect the device from excessive current draw.
  • A 1uF to 10uF ceramic or film capacitor with an X5R or X7R dielectric is recommended for input decoupling. The capacitor should be placed as close as possible to the input pin of the device.
