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

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific batch. Ensure storage conditions adhere to moisture sensitivity levels prior to soldering. Validate package integrity against TO-252-3 specifications before integration into PCB designs.

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

Select this component when an adjustable LDO with high input voltage tolerance up to 36 V is required. Consider the 500 mA output capability and low quiescent current of 30 uA for battery-sensitive designs. Evaluate thermal performance given the 1.2 W power dissipation limit in the TO-252-3 package. Compare against fixed-output alternatives if voltage flexibility is not necessary.
