S-816A29AMC-BAET2U

Overview

The S-816A29AMC-BAET2U is a fixed-output low-dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides a stable 2.9 V output with a maximum output current of 300 mA. The device operates within an input voltage range of 1.5 V to 6.0 V and maintains a typical dropout voltage of 400 mV at full load. It features a quiescent current of approximately 1.0 µA, ensuring minimal power consumption in standby modes. The unit offers a voltage regulation accuracy of ±2% and supports operation across a temperature range from -40°C to +85°C. Packaged in a compact SOT-23-5 surface-mount format, it is designed for efficient space-constrained applications requiring reliable linear regulation.

Procurement Notes

Verify the specific suffix BAET2U against official ABLIC documentation to confirm pinout compatibility and tape-and-reel specifications. Ensure the sourcing channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with distributor databases to confirm current production status and availability constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.9 V rail is required with moderate current demands under 300 mA. The low quiescent current makes it suitable for energy-efficient designs where standby power loss is critical. Verify that the input voltage remains above the minimum operating threshold while accounting for the dropout voltage under maximum load conditions to maintain regulation stability.
