Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the exact suffix 'CST' corresponds to the SOT-223 package and 2.85V fixed output variant. Confirm manufacturer status as Microsemi or its successor entity, noting potential lifecycle changes. Ensure compatibility with existing PCB footprints for SOT-223 components during sourcing.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a precise 2.85V output is required rather than adjustable regulation. Consider the 1A current limit and 12V maximum input voltage constraints. Evaluate thermal dissipation requirements based on the voltage drop between input and output currents in the final application design.
