Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' indicates the 4 V fixed output variant, as the XC9236 series uses letter codes for different voltage settings. Confirm the SOT-25-5 package type matches your PCB footprint requirements. Ensure compatibility with the 2 V to 6 V input range for your specific application circuit design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a stable 4 V rail is required from a single-cell lithium battery or similar 2-6 V source. The synchronous design offers higher efficiency than asynchronous alternatives at moderate loads. Consider the 15 uA quiescent current for battery life optimization in standby modes.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9236 family of synchronous step-down converters. Other variants in this series, such as XC9236B09CMR-G (0.9 V) and XC9236A24CMR-G (2.4 V), share identical electrical characteristics and packaging but differ in their fixed output voltage settings defined by the middle letter code.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9236 variants with different fixed outputs if voltage adjustment is possible, or XC9235 series parts which share the same pinout and performance profile.
