Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics, as variations exist within the series. Ensure compatibility with the target PCB footprint, specifically the SOT-25-5 package dimensions. Confirm RoHS compliance status through the manufacturer's certification documents prior to integration into regulated assemblies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from low-voltage sources starting at 650 mV. The 1.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 800 mA output capability relative to peak load requirements and thermal constraints inherent to the small SOT-25-5 package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9141 series of synchronous step-up converters. It shares architectural similarities with other variants in the lineup but differs in fixed output voltage settings and switching frequencies. The 'C' suffix typically denotes the 1.2 MHz switching frequency variant, distinguishing it from higher-frequency options like the 'D' series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9141B33CMR-G offers identical topology and package but provides a 3.3 V fixed output instead of 5 V.
