S-816A25AMC-BAAT2G

Overview

The S-816A25AMC-BAAT2G is a linear regulator controller IC manufactured by ABLIC Inc. It requires an external N-channel MOSFET to function as a low-dropout voltage regulator. The device provides a fixed output voltage of 2.5 V and supports a maximum output current of 1 A when paired with the appropriate external transistor. It is housed in a compact SOT-23-5 package, designed for surface-mount installation. This component belongs to the S-816 series of power management integrated circuits.

Feature Summary

• Functions as a linear regulator controller requiring an external N-channel MOSFET for operation
• Provides a fixed 2.5 V output voltage level
• Capable of delivering up to 1 A output current with suitable external components
• Utilizes a compact SOT-23-5 surface-mount package

Applications

• Battery-powered portable electronic devices requiring stable 2.5 V supply
• Embedded systems utilizing external high-current transistors for regulation
• Low-voltage power management circuits in consumer electronics

Procurement Notes

Verify the specific suffix BAAT2G against official ABLIC documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with external N-channel MOSFET selection for the required 1 A load. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.5 V output is required with high current capability exceeding internal regulator limits. The design must incorporate an external N-channel MOSFET to handle the 1 A load. Consider the SOT-23-5 footprint constraints and thermal dissipation requirements associated with the external pass element during PCB layout.

Part Context

This part is a member of the ABLIC S-816 series, which focuses on low-power linear regulator controllers. Unlike standard LDOs with integrated pass transistors, this series separates the control logic from the power stage, allowing designers to optimize efficiency and current handling using discrete external components tailored to specific application needs.

Replacement Considerations

Direct replacements within the S-816 series include variants with different fixed output voltages, such as the S-816A30AMC-BAAT2G (3.0 V) or S-816A37AMC-BAMT2G (3.7 V). Verify that the external MOSFET interface remains compatible across these substitutes.
