LP873220RHDR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the LP873220RHDR evaluation module documentation, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The LP873220RHDR has a programmable output voltage, which can be set using the I2C interface. The device has a default output voltage of 1.8V, but it can be changed by writing to the VOUT_MODE and VOUT_TRIM registers. Refer to the datasheet for the specific register settings and voltage ranges.
  • The LP873220RHDR has an absolute maximum input voltage rating of 5.5V. However, the recommended operating input voltage range is 2.7V to 5.5V. Exceeding the absolute maximum rating can damage the device.
  • To ensure the LP873220RHDR is in a low-power state during shutdown, make sure to set the EN pin low and the PG pin high. This will put the device in a low-power shutdown mode, reducing the quiescent current to less than 1 μA.
  • The LP873220RHDR has a thermal derating of 12.5 mW/°C above 25°C. This means that the device's power dissipation rating decreases by 12.5 mW for every degree Celsius above 25°C. Ensure proper thermal management to prevent overheating and maintain reliable operation.
