Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'D28C0R' against official Torex documentation to confirm the 2.8V fixed output configuration. Ensure the component matches the required SOT-25-5 package dimensions and thermal characteristics for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.8V output is required from low-voltage sources. The 500mA current limit suits moderate load applications. Consider the 3MHz frequency for smaller external inductor sizes compared to lower-frequency alternatives. Verify that the input voltage source can reliably sustain the minimum 0.65V threshold during operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9141 series, which are high-efficiency synchronous step-up converters. The series is characterized by its ability to operate from very low input voltages and includes integrated load disconnect features. The XC9141D variant specifically denotes the 500mA output current class within the broader product family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9141 series variants with matching 2.8V output and 500mA current ratings, such as XC9141D28CMR-G or XC9141D28DER-G, provided the pinout and package compatibility are confirmed.
