S-816A41AMC-BAQT2G

Overview

The S-816A41AMC-BAQT2G is a linear voltage regulator controller manufactured by ABLIC Inc., belonging to the S-816 series. It operates with an input voltage range up to 16V and delivers a fixed output of 4.1V when paired with an external transistor. The device consumes 40µA of supply current and functions within a temperature range of -40°C to +85°C. It is housed in a compact SOT-23-5 package, suitable for surface mount installation.

Feature Summary

• Functions as a control IC requiring an external power transistor for voltage regulation
• Provides a fixed 4.1V output level
• Operates with low quiescent current consumption
• Supports wide input voltage ranges up to 16V

Applications

• Battery-powered portable electronics
• Low-power embedded systems
• Consumer devices requiring stable voltage rails

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent design changes via official Product Change Notices (PCNs). Ensure the specific suffix matches required packaging and marking specifications before finalizing orders.

Selection Notes

This component requires an external N-channel MOSFET or BJT to function as a complete regulator circuit. Designers must account for thermal dissipation of the external pass element. Verify that the load current requirements do not exceed the capabilities of the selected external transistor and that the input voltage remains within the specified 16V limit.

Part Context

Part of the ABLIC S-816 series of CMOS voltage regulators. This specific model utilizes an external transistor topology rather than an integrated pass element, offering flexibility in current handling while maintaining a small footprint in the SOT-23-5 package.

Replacement Considerations

Check for updated suffixes such as -BAVT2X which may indicate revised manufacturing data or packaging variations. Consult official substitution guides for equivalent controllers with similar input/output characteristics.
