S-816A45AMC-BAUT2G

Overview

The S-816A45AMC-BAUT2G is a linear low-dropout voltage regulator manufactured by ABLIC Inc. It provides a fixed output voltage of 4.5 V with a maximum output current capability of 1 A. The device operates within an input voltage range up to 16 V and maintains a typical dropout voltage of 100 mV at rated load. It features a voltage regulation accuracy of 2% and supports surface-mount installation in an SOT-23-5 package. The component is designed for operation across a temperature range from -40°C to +85°C.

Feature Summary

• Fixed output voltage configuration ensuring stable power delivery without external adjustment components
• High output current capability suitable for driving moderate power loads efficiently
• Low dropout characteristic enabling efficient operation with minimal input-to-output voltage differential

Applications

• Battery-powered portable electronic devices requiring stable voltage rails
• Embedded systems needing regulated power supply for microcontrollers or logic circuits
• General-purpose power management in consumer electronics

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Availability is restricted, and it is not currently stocked by major distributors such as Mouser. Verification of final stock availability and alternative sourcing channels is required before procurement planning. Designers should consider obsolescence risks when integrating this part into new products.

Selection Notes

Select this regulator when a fixed 4.5 V output with 1 A capacity is required in a compact SOT-23-5 footprint. Ensure the application input voltage does not exceed 16 V and thermal dissipation requirements are met within the specified operating temperature range. Verify that the 2% accuracy meets system tolerance needs.

Part Context

Part of the S-816 series of LDO regulators from ABLIC, designed for low-voltage operation with high accuracy. This specific model offers a higher output current compared to lower-power variants in the same family, making it suitable for applications demanding more robust power delivery while maintaining small form factor constraints.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the EOL status, engineers must identify compatible alternatives based on pin compatibility, electrical specifications, and package dimensions through independent cross-reference tools.
