S-816A34AMC-BAJT2G

Overview

The S-816A34AMC-BAJT2G is a fixed positive linear regulator controller IC manufactured by ABLIC Inc. It operates with an output voltage of 3.4 V and supports an output current of 1 A. The device utilizes an external transistor configuration and is housed in a SOT-23-5 package. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes an external transistor for high-current regulation
• Provides fixed positive output voltage control
• Designed for low-voltage operation applications

Applications

• Battery-powered portable devices requiring precise voltage control
• Embedded systems needing high-output current regulation
• General-purpose power management circuits

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to ensure correct pinout and electrical characteristics. Confirm availability status as distribution channels may vary. Ensure compatibility with external pass transistors specified in the datasheet for proper thermal and electrical performance.

Selection Notes

Select this component when an integrated LDO is insufficient due to current requirements exceeding internal limits. The external transistor design allows for higher power dissipation handling. Verify that the application circuit can accommodate the additional external components required for controller operation.

Part Context

This part belongs to the S-816 series of linear regulator controllers from ABLIC. Unlike standard monolithic LDOs, this series requires an external NPN or PNP transistor to handle the load current, offering flexibility in thermal management and current capacity beyond what is possible with fully integrated solutions.

Replacement Considerations

S-816A33AMC-BAIT2U is a documented alternative within the same family, differing primarily in the fixed output voltage setting.
