S-816A31AMC-BAGT2G

Overview

The S-816A31AMC-BAGT2G is a fixed-output low dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides a stable 3.1 V output with a maximum load current of 1 A. The device supports an input voltage up to 16 V and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a typical dropout voltage of 100 mV, line regulation of 0.15% per volt, and load regulation of 60 mV. The unit features a power dissipation rating of 600 mW and maintains a voltage regulation accuracy of 2%. It is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• High output current capability of 1 A for demanding loads
• Low dropout voltage characteristic for efficient power management
• Wide input voltage range supporting up to 16 V
• Compact SOT-23-5 package suitable for space-constrained designs

Applications

• Portable electronic devices requiring stable 3.1 V supply
• Battery-powered systems needing high efficiency

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific manufacturing batch. Check for obsolescence notices or last-time buy deadlines from ABLIC. Ensure storage conditions prevent moisture damage prior to reflow soldering. Validate pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this regulator when a fixed 3.1 V output is required with high current capacity. Consider the 16 V input tolerance for noisy environments. Evaluate thermal performance given the 600 mW dissipation limit in the small package. Compare against other S-816 variants if different voltage levels are needed. Ensure the application does not exceed the specified operating temperature range.
