Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific output voltage (2.85 V) and switching frequency (1.2 MHz) against design requirements. Confirm the SOT-89-5 package compatibility with your PCB layout. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer part number with official datasheets to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 2.85 V output is required from a 5.5 V maximum input source. The SOT-89-5 package suits applications with limited board space. Consider the 1.2 MHz frequency for balancing component size and efficiency. Verify that the 1.5 A output current capability aligns with the system's peak load demands.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9288 series of synchronous buck converters. The series is characterized by high efficiency and compact packaging options. The 'B' suffix typically denotes specific electrical characteristics or pin configurations within the family. The 'LDPR' indicates the fixed output voltage, package type, and reel packaging format.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for other XC9288 variants with different fixed output voltages if 2.85 V is not suitable. Compare packages such as USP-C-EP-6 for alternative form factors. Verify switching frequency differences if EMI filtering requirements change.
