Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SDX' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits. Cross-reference pinouts with the latest TI documentation to avoid compatibility issues during PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for converting higher bus voltages down to lower logic or analog levels. The 1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 600 mA output limit against peak load requirements. Evaluate thermal performance based on the WSON-10 package's thermal resistance characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM269x family of high-voltage step-down regulators. It shares architectural similarities with other members like the LM2694SD and LM2695 series, differing primarily in output current capabilities and package options. The family targets applications needing robust performance in space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2694SD/NOPB for identical specifications in different packaging. LM2695SDX/NOPB offers higher current capacity but requires verification of thermal and footprint compatibility.
