S-816A26AMC-BABT2U

Overview

The S-816A26AMC-BABT2U is a fixed-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides a stable 2.6 V output with a maximum continuous current of 1 A. The device operates within an input voltage range up to 16 V and features a typical dropout voltage of 100 mV at full load. It offers a voltage regulation accuracy of 2% and includes internal protection mechanisms. The component is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained portable electronics.

Feature Summary

• Provides a fixed 2.6 V output voltage with high precision
• Supports up to 1 A output current capability
• Features low dropout voltage for efficient power management
• Integrated overcurrent and thermal shutdown protection

Applications

• Portable battery-powered devices requiring stable voltage rails
• Cellular phones and mobile communication equipment
• Handheld instruments and medical devices
• General-purpose low-noise power supply circuits

Procurement Notes

Verify the specific suffix 'BABT2U' against official ABLIC documentation to confirm pinout, tolerance, and packaging details. Ensure compatibility with existing PCB footprints for the SOT-23-5 package. Confirm end-of-life status or obsolescence notices if sourcing from secondary markets, as availability may vary significantly across distributors.

Selection Notes

Select this component when a fixed 2.6 V rail is required with high current capacity in a small footprint. Compare dropout characteristics against load requirements to ensure regulation stability. Consider the 16 V maximum input rating for systems with higher supply voltages. Evaluate thermal performance based on expected power dissipation in the SOT-23-5 package.

Part Context

This part belongs to the ABLIC S-816 series of LDO regulators, designed for portable applications. The series emphasizes low noise and high ripple rejection. The S-816A variant typically integrates external transistors or uses internal pass elements optimized for high current. The 'MC' designation often refers to specific package or tolerance variations within the family.

Replacement Considerations

Direct substitutes include other ABLIC S-816 series parts with identical 2.6 V output and SOT-23-5 packaging, such as S-816A26AMC-BAT2U. Verify that alternative manufacturers offer comparable 1 A current ratings and similar dropout voltages to maintain circuit performance without redesign.
