S-816A38AMC-BANT2G

Overview

The S-816A38AMC-BANT2G is a linear regulator controller IC from ABLIC Inc., designed for use with external transistors. It provides a fixed output voltage of 3.8 V and supports an output current of 1 A. The device operates within an input voltage range up to 16 V and features a surface-mount SOT-23-5 package. It functions across a temperature range of -40°C to +85°C.

Feature Summary

• Controller architecture requiring external P-channel or N-channel transistors
• Fixed 3.8 V output regulation capability
• High current handling capacity via external pass element

Applications

• Battery-powered portable electronics
• Embedded systems requiring stable low-noise power rails
• Industrial control modules needing high-current regulation

Procurement Notes

Verify the specific external transistor requirements, as this component acts as a controller rather than a standalone regulator. Confirm package compatibility with the SOT-23-5 footprint and ensure thermal management strategies align with the 1 A output capability. Cross-reference the manufacturer's datasheet for precise drive characteristics and protection feature implementations.

Selection Notes

Select this component when system design necessitates higher output currents than standard monolithic LDOs can provide. It allows customization of the pass element to match specific efficiency or dropout voltage targets. Ensure the external transistor selection complements the controller's drive capabilities and thermal constraints for optimal performance.

Part Context

This part belongs to the S-816 series of linear regulator controllers. Unlike integrated LDOs, it separates the control logic from the power stage, offering flexibility in power dissipation distribution. It is categorized under PMIC solutions for applications demanding customizable power delivery architectures.

Replacement Considerations

Direct replacements are limited due to the controller topology. Evaluate other S-816 series variants or similar controller ICs from ABLIC that match the 3.8 V reference and drive requirements. Verify pinout compatibility if substituting with different package options.
