Procurement Notes

Verify the complete part number including suffix NYQTFG to ensure correct packaging and tape-and-reel configuration. Confirm that the 3.1 V output aligns with target circuit requirements. Check RoHS compliance status if restricted substances are mandated. Ensure ESD handling protocols are followed during assembly due to the small SOT-23-5 footprint.

Selection Notes

Select this regulator when a fixed 3.1 V supply is required with moderate current demands. The SOT-23-5 package suits designs with limited board space. Consider the 80 mV dropout characteristic for efficiency near minimum input voltages. Verify thermal dissipation capabilities within the -40 °C to +85 °C operational window for the specific application environment.

Part Context

This component belongs to the S-1111 series of low-dropout regulators from ABLIC Inc., known for precision analog semiconductor solutions. The series offers fixed output options optimized for portable and industrial electronics.
