Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when sourcing from distributors. Confirm the manufacturer is STMicroelectronics to ensure component authenticity. Check RoHS compliance status if required for your assembly process. Ensure the SOT-23-5 footprint matches your board design before ordering.
Selection Notes
Select this component when a fixed 3.3V rail is needed with moderate current demands up to 50mA. It is appropriate for applications prioritizing low noise and low quiescent current over high power delivery. Consider the 120mV dropout characteristic against your minimum input voltage constraints.
Part Context
This part belongs to the LD2982 series of low-dropout regulators from STMicroelectronics. It shares architectural similarities with the LD2981 series but offers different current ratings and package options. The series is categorized under PMIC - Power Management ICs, specifically linear voltage regulators.
