Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'MM' corresponds to the SOT-23-3 package variant when sourcing, as packaging options may vary within the family. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain partners provide valid traceability records. Cross-reference ordering information with the latest datasheet to avoid discrepancies between legacy part numbers and current production versions. Validate component authenticity through authorized distribution channels only.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.0V reference is required instead of the standard 2.43V baseline found in other series members. It is suitable for designs needing higher voltage levels without external resistor dividers. Consider the SOT-23-3 footprint for board space optimization. Evaluate thermal management requirements if operating near maximum current limits. Compare against adjustable alternatives if variable reference voltages are needed for system calibration purposes.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM335 family of precision shunt voltage references, which are widely used in instrumentation and control systems. Unlike the adjustable LM334 or other fixed variants, the LM3354 specifically targets the 5.0V market segment. It shares architectural similarities with the LM431 but offers distinct package and accuracy specifications tailored for general-purpose precision applications. The NOPB suffix indicates lead-free and environmentally friendly manufacturing compliant with global standards.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM335AMX/NOPB: Fixed 2.43V reference in SOIC-8 package; requires circuit redesign for voltage level changes. LM431AIM3X/NOPB: Adjustable shunt reference in SOT-23-3; offers flexibility but lacks fixed 5.0V output. LM336ZIMX/NOPB: Fixed 2.5V reference in SOIC-8; different voltage specification necessitates hardware modification.
