S-816A55AMC-BBET2G

Overview

The S-816A55AMC-BBET2G is a CMOS voltage regulator manufactured by ABLIC Inc., designed for external transistor applications. It features a fixed positive output of 5.5V with a maximum output current of 1A and a maximum input voltage of 16V. The device utilizes an SOT-23-5 package and operates within a temperature range suitable for standard commercial applications.

Feature Summary

• Supports high output current capability through external transistor configuration
• Provides stable fixed voltage regulation for single-output applications
• Utilizes CMOS technology for efficient power management

Applications

• Battery-powered devices requiring regulated power supply
• General-purpose linear regulation in portable electronics
• Systems utilizing external pass transistors for current boosting

Procurement Notes

Verify the specific ordering suffix to ensure correct pinout and functional configuration, as variations exist within the S-816 series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure that the design accommodates the necessary external components specified in the official datasheet for optimal performance and thermal management.

Selection Notes

Select this component when a fixed 5.5V output is required with higher current capabilities than internal LDOs can provide. The external transistor design allows for flexibility in handling higher load currents while maintaining regulation. Consider the SOT-23-5 package constraints and thermal dissipation requirements associated with the external pass element during the selection process.

Part Context

This part belongs to the S-816 series of CMOS voltage regulators from ABLIC Inc. Unlike integrated LDOs, this series is specifically engineered for use with external NPN or PNP transistors to achieve higher output currents. It serves as a versatile solution for power management in applications where standard fixed regulators are insufficient due to current demands.

Replacement Considerations

Direct substitutes may include other ABLIC S-816 series variants with different output voltages or current ratings. Verify compatibility with existing external transistor circuits and thermal design when considering alternative models within the same family.
