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

Verify the specific ordering suffix '13' corresponds to the SOT-89 package and tape & reel quantity as defined in the manufacturer's ordering guide. Confirm that the component status aligns with project requirements, noting that this series may be marked as not recommended for new design. Ensure compliance with RoHS 3 directives and check for any applicable PCN regarding product changes or end-of-life notifications before finalizing procurement.

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

Select this regulator when a stable 3.6V rail is required from inputs varying between 3.2V and 18V. The SOT-89 package offers higher thermal dissipation compared to smaller footprints, suitable for sustained 300mA loads. Verify that the application does not require adjustable output voltages, as this part is fixed. Consider the dropout voltage specifications relative to the minimum expected input voltage to maintain regulation during peak current draw.
