S-816A27AMC-BACT2U

Overview

The S-816A27AMC-BACT2U is a fixed-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides a stable 2.7 V output with a maximum continuous current 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 full load. Voltage regulation accuracy is specified at 2%. It functions in a positive polarity configuration with a single output channel, housed in an SOT-23-5 surface-mount package suitable for space-constrained designs.

Feature Summary

• Delivers high output current capability of 1 A for powering demanding loads
• Maintains low dropout voltage to ensure efficiency under varying input conditions
• Provides precise voltage regulation with tight tolerance for sensitive circuitry

Applications

• Portable electronic devices requiring stable power rails
• Battery-powered systems needing efficient linear regulation
• Embedded circuits utilizing microcontrollers or sensors

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required output voltage and package type for your PCB layout. Cross-reference the manufacturer's latest datasheet for any updates on environmental compliance or recommended operating conditions before finalizing procurement.

Selection Notes

Select this component when a 1 A output current is necessary alongside a fixed 2.7 V rail. Consider the SOT-23-5 package constraints regarding thermal dissipation and board space. Verify that the input voltage remains within the specified maximum limit to prevent device damage. Evaluate the dropout performance relative to your minimum battery voltage to ensure regulation stability throughout discharge cycles.

Part Context

This part belongs to the S-816 series of LDO regulators from ABLIC, designed for general-purpose power management. The series offers various fixed output voltages and packaging options to suit different application requirements.
