LD2982AM25R

Overview

The LD2982AM25R is a fixed output voltage regulator from STMicroelectronics, providing a stable 2.5V output with a maximum current of 50 mA. It features a very low dropout voltage and low noise characteristics, making it suitable for sensitive analog circuits. The device operates within an extended temperature range of -40°C to 125°C and is housed in a compact SOT-753 (SC-74A) package.

Feature Summary

Very low dropout voltage operation
Low noise performance for sensitive applications
Integrated inhibit function

Applications

Battery-powered systems requiring efficient voltage regulation
Portable devices with space constraints
Low noise analog circuit power supplies

Procurement Notes

Verify component status as the LD2982AM25R is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure substitute components meet original electrical specifications and pin compatibility requirements before integration into designs.

Selection Notes

Select this component for applications requiring a precise 2.5V reference with minimal quiescent current. Consider the SOT-753 package size for space-limited PCB layouts. Evaluate thermal performance under load conditions within the specified operating temperature range to ensure reliability.

Part Context

This linear voltage regulator belongs to the LD2982 series, designed for low-power applications. It complements other PMIC solutions from STMicroelectronics, offering a simple, cost-effective regulation solution for fixed voltage needs in consumer electronics and industrial control systems.

Replacement Considerations

The LP2985AIM5-2.5/NOPB from Texas Instruments is identified as a similar substitute. Verify pinout compatibility and current handling capabilities when transitioning to alternative sources due to the obsolete status of the original part.
