S-816A30AMC-BAFT2G

Overview

The S-816A30AMC-BAFT2G is a low dropout CMOS voltage regulator manufactured by ABLIC Inc. It provides a fixed output voltage of 3.0 V with an accuracy of ±2.0%. The device operates within an input voltage range of 1.5 V to 5.5 V and supports a maximum output current of 1 A. Key electrical parameters include a typical dropout voltage of 100 mV at 1 A, a quiescent current of 1 µA during operation, and a power-off current of 100 nA. It features built-in protection circuits for overcurrent, thermal shutdown, and reverse polarity. The component is housed in a compact SOT-23-5 package and is rated for an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Ultra-low current consumption with 1 µA typical quiescent current and 100 nA power-off current.
• High output current capability of 1 A with a low dropout voltage of 100 mV (typical).
• Built-in protective functions including overcurrent protection, thermal shutdown circuit, and reverse polarity protection.
• Stable operation without external capacitors required for most fixed output voltages.

Applications

• Battery-powered portable devices requiring extended standby time.
• Power supply stages for microcontrollers and sensors.
• Consumer electronics utilizing single-cell lithium-ion or alkaline batteries.

Procurement Notes

Verify the specific suffix codes against official ABLIC documentation to confirm pin configuration and package type. Confirm RoHS compliance status through the manufacturer's datasheet. Check for end-of-life notifications as this series may have discontinuation updates. Ensure the ordering code matches the exact output voltage and tolerance requirements for your design.

Selection Notes

Select this component when high output current is needed alongside minimal standby power drain. The S-816 series is suitable for applications where space is limited due to the small SOT-23-5 package. Consider the dropout voltage characteristics relative to the minimum battery voltage in your system. Verify that the load current does not exceed the absolute maximum ratings under all operating conditions.

Part Context

This part belongs to the S-816 Series of low dropout regulators from ABLIC. The series is characterized by its ultra-low current consumption and high output current drive capability. It utilizes CMOS technology to achieve performance metrics suitable for modern portable electronics. The S-816 series complements other ABLIC LDOs like the S-814 and S-818 series, offering higher current capacity than the S-814 while maintaining low quiescent current.

Replacement Considerations

Direct replacements must match the 3.0 V output, 1 A current rating, and SOT-23-5 package. Verify pinout compatibility before substitution. Other ABLIC parts in the S-816 family with different voltage outputs may be compatible if voltage levels are adjusted.
