MIC37100-1.8WS Frequently Asked Questions (FAQ)

  • A good PCB layout for optimal thermal performance involves placing the MIC37100-1.8WS near a thermal pad or a heat sink, and ensuring good copper pour and thermal vias to dissipate heat efficiently.

  • To ensure stability and prevent oscillations, it's essential to follow the recommended component values and PCB layout guidelines, and to add a capacitor (e.g., 10uF) in parallel with the output capacitor to filter out high-frequency noise.

  • Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.

  • While the MIC37100-1.8WS is rated for operation up to 125°C, it's essential to consider the thermal derating and ensure that the device is properly heat-sinked to prevent overheating and ensure reliable operation.

  • To troubleshoot issues, start by verifying the input voltage, output voltage, and current consumption. Check the PCB layout and component values, and ensure that the device is properly heat-sinked. Use an oscilloscope to analyze the output voltage waveform and identify any noise or oscillations.
