Procurement Notes

Verify the specific suffix 'BBAT2G' against the official ABLIC datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Check for RoHS compliance status as indicated in the manufacturer's documentation. Confirm availability status directly with authorized distributors or ABLIC, as supply chain conditions may vary.

Selection Notes

Select this component when a stable 5.1 V rail is required with high current drive capabilities. The low dropout voltage makes it suitable for applications where the input voltage is close to the output level. Verify that the thermal performance of the SOT-23-5 package can handle the expected power dissipation under maximum load conditions. Consider the 2% accuracy tolerance for precision requirements.

Part Context

This part belongs to the S-816A series of LDO regulators from ABLIC. The series is characterized by CMOS technology, offering a balance of high output current and low quiescent current. The S-816A series is designed for general-purpose voltage regulation in various electronic applications requiring reliable power supply stability.

Replacement Considerations

Direct substitutes must match the 5.1 V output, 1 A current rating, SOT-23-5 package, and 16 V max input voltage. Verify equivalent dropout voltage and regulation accuracy. Cross-reference with other ABLIC S-816 variants if pinout compatibility is critical.
