• Consumer devices with limited power budgets

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against official datasheets to confirm pinout and thermal pad configuration. Ensure compatibility with the target PCB footprint, specifically the USP-C-EP-6 package dimensions. Confirm that the fixed 2.2 V output meets the load requirements without external adjustment resistors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.2 V output is required within a 1.8 V to 6 V input range. The manual mode switching allows optimization for either low noise or high light-load efficiency. Verify that the 600 mA output current capacity aligns with the peak demand of the application circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the XC9237 series, which offers flexible control modes. This specific variant uses the G-series input range starting at 1.8 V. It differs from A-C series parts by its lower minimum input voltage specification while maintaining similar output current capabilities.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9237G22CMR-G shares identical electrical specifications but uses an SOT-25-5 package instead of USP-C-EP-6. Verify package compatibility before substitution.
