MIC26903YJL-TR Frequently Asked Questions (FAQs)

  • A good PCB layout for optimal thermal performance involves placing the MIC26903YJL-TR near a thermal pad or a heat sink, and ensuring good airflow around the device. The PCB should also have sufficient copper area to dissipate heat.
  • To ensure reliable start-up, ensure that the input voltage rises monotonically and does not droop during start-up. Also, ensure that the input capacitor is properly sized to handle the inrush current.
  • The recommended input capacitor value is 10uF to 22uF, and the type should be a low-ESR ceramic capacitor, such as X5R or X7R, to minimize voltage ripple and ensure stable operation.
  • To optimize the MIC26903YJL-TR for low standby power consumption, ensure that the enable pin is properly driven to shut down the device when not in use, and consider using a low-power mode or shutdown mode if available.
  • The maximum allowed voltage on the output of the MIC26903YJL-TR is 5.5V, and exceeding this voltage may damage the device.
