Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact performance grades and testing standards. Ensure that the required operating temperature range aligns with the component's specified limits. Confirm package compatibility during integration planning. Cross-reference datasheet revisions to ensure parameter consistency. Validate all electrical characteristics prior to final design approval.

Selection Notes

Select this component when a precise 36 V regulation point is required in high-reliability designs. Consider the axial leaded format for standard through-hole assembly processes. Evaluate the thermal management requirements based on the 1 W power rating. Assess the impact of the 50 Ohm impedance on circuit stability. Verify that the wide temperature capability meets the environmental constraints of the target application.
