Procurement Notes
Verify the specific suffix MSKQTRT-01 against official Semtech documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints designed for SOT-23-3 packages. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration before procurement.
Selection Notes
Select this component when a precise, adjustable voltage reference is required for shunt regulation applications. Consider its wide current range and low dynamic impedance for stability in switching power supply feedback loops. Verify that the industrial temperature range meets the operational environment requirements of the target system.
Part Context
This part belongs to the SC431 series of adjustable shunt regulators produced by Semtech. These devices are widely used as voltage references and control elements in power management circuits. The series offers alternatives to legacy components like TL431, providing modern performance characteristics in compact surface-mount packages suitable for space-constrained designs.
Replacement Considerations
Publicly confirmed substitute part numbers include TL1431, TL431, LM431, and AS431. Verify pinout compatibility and electrical parameter tolerances before substituting these equivalents in existing designs.
