Voltage Regulators - Linear Regulator Controllers Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to ensure correct pinout and electrical characteristics. Confirm that the external transistor requirement is accounted for in the system design. Check RoHS compliance status through manufacturer datasheets before integration. Ensure the selected package variant matches the PCB footprint requirements exactly.

Voltage Regulators - Linear Regulator Controllers Selection Notes

Select this component when a fixed 5.7 V output is required with higher current capability than internal LDOs can provide. The external transistor design allows for thermal management flexibility. Consider the SOT-23-5 package constraints for space-limited applications. Verify input voltage stability to maintain regulation within the specified dropout limits.

Voltage Regulators - Linear Regulator Controllers Part Context

This part belongs to the S-816 series of CMOS voltage regulators from ABLIC. The series is characterized by its use of external pass transistors to achieve higher output currents while maintaining low quiescent current. These regulators are intended for applications where standard integrated LDOs lack sufficient current handling or thermal dissipation capabilities.

Voltage Regulators - Linear Regulator Controllers Replacement Considerations

Direct substitutes must match the 5.7 V fixed output, 1 A current rating, and SOT-23-5 package. Verify compatibility with external transistor selection if using alternative parts. Cross-reference pinouts carefully as external transistor configurations may vary between manufacturers.
