S-816A47AMC-BAWT2U

Overview

The S-816A47AMC-BAWT2U is a fixed positive linear low-dropout (LDO) voltage regulator manufactured by ABLIC. It provides a nominal output voltage of 4.7 V with a maximum output current capability of 1 A. The device operates within an input voltage range up to a maximum of 16 V and maintains a typical dropout voltage of 100 mV at rated load. It features a voltage regulation accuracy of 2.0% and consumes a quiescent current of approximately 1 µA. The component is housed in a compact SOT-23-5 surface-mount package and is designed for operation across a temperature range from -40 °C to +85 °C.

Feature Summary

• Ultra-low quiescent current consumption of 1 µA for extended battery life
• High output current capability of 1 A with minimal voltage drop
• Compact SOT-23-5 surface-mount packaging for space-constrained designs

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Embedded systems needing stable 4.7 V logic supply rails
• Industrial control modules operating in wide temperature environments

Procurement Notes

Verify the specific suffix BAWT2U against official ABLIC documentation, as this variant may be discontinued or subject to end-of-life notices. Confirm availability through authorized distributors and check for valid RoHS compliance status prior to procurement. Ensure design-in compatibility with existing PCB footprints and thermal requirements.

Selection Notes

Select this component when a high-current LDO with ultra-low standby current is required. The 4.7 V output suits specific logic families or sensor interfaces. Evaluate thermal dissipation capabilities given the 1 A output and SOT-23-5 package constraints. Compare against newer series if long-term supply assurance is critical due to potential discontinuation status.
