Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DPR-G against official Torex documentation to confirm the SOT-89-5 package and pinout configuration. Ensure compatibility with your system's thermal requirements given the small form factor. Cross-reference the datasheet for exact electrical tolerances and recommended external component values before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3V output is required from a 2.5V to 5.5V input source. The 1.5A current capacity suits moderate load applications. Consider the SOT-89-5 package if board space allows, noting that smaller packages like USP-C are available in other variants within the same family for tighter layout constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9288 series of HiSAT-COT synchronous buck converters. The series is characterized by high efficiency and stability under light loads. Other variants in the lineup offer different fixed output voltages or alternative packaging options such as USP-C, allowing designers to scale power density while maintaining consistent control architecture and operational characteristics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9288A variants with identical pinouts but different output voltages, such as XC9288A25DPR-G (2.5V) or XC9288A3ACPR-G (3.05V). Verify that the replacement part maintains the same SOT-89-5 package and electrical ratings to ensure mechanical and functional compatibility.
