LD2980ABM25TR

Overview

The LD2980ABM25TR is a low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a fixed positive output voltage of 2.5V with a maximum continuous output current capability of 50mA. The device utilizes an SOT-23-5 surface-mount package and operates within an extended temperature range from -40°C to +125°C. Designed for stability with low equivalent series resistance (ESR) ceramic capacitors, it features internal current limiting and thermal shutdown protection mechanisms.

Feature Summary

Ultra-low dropout voltage performance optimized for battery-powered systems
Logic-controlled electronic shutdown function via inhibit pin
Stable operation when used with low ESR ceramic output capacitors

Applications

Battery-powered instrumentation systems
Low noise power supply circuits
Industrial control boards requiring local regulation

Procurement Notes

Verify the specific suffix 'ABM25' against official STMicroelectronics documentation to confirm the exact output voltage tolerance and package variant. Ensure compatibility with low ESR ceramic capacitors as specified in the datasheet. Confirm lead times and production status directly with authorized distributors or the manufacturer.

Selection Notes

Select this component for applications requiring precise 2.5V regulation with minimal voltage drop. Consider the SOT-23-5 package constraints for PCB layout. Evaluate quiescent current requirements, noting the sleep mode consumption when the inhibit pin is active. Verify input voltage ranges do not exceed maximum ratings under all operating conditions.

Part Context

This part belongs to the LD2980 family of ultra-low drop voltage regulators designed for low noise and low power applications. The family supports various fixed output voltages and includes logic-controlled shutdown features. These regulators are engineered for high accuracy and fast dynamic response, making them suitable for sensitive analog and digital loads in portable devices.
