LD2980CM50TR

Overview

The LD2980CM50TR is a fixed positive low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 5 V output with a maximum current capability of 50 mA. The device utilizes an SOT-23-5 surface-mount package and operates within a temperature range of -40°C to +125°C. Key electrical characteristics include a typical dropout voltage of 0.225 V at full load, a quiescent current of 150 µA in active mode, and a power supply rejection ratio of 63 dB at 1 kHz. It incorporates internal protection mechanisms against overcurrent and thermal overload.

Feature Summary

Stable operation guaranteed with low equivalent series resistance (ESR) ceramic capacitors
Logic-controlled electronic shutdown function for system power management
Integrated thermal and current limiting protection circuits

Applications

Battery-powered portable systems requiring low quiescent current
Instrumentation and industrial control boards
Post-regulation stages for switching power supplies

Procurement Notes

Verify the component status as discontinued or obsolete before procurement planning. Confirm availability of qualified replacement components from alternative manufacturers such as Texas Instruments. Ensure that the selected substitute maintains compatibility with the required SOT-23-5 footprint and electrical specifications to avoid redesign efforts.

Selection Notes

Select this component for applications prioritizing stability with ceramic output capacitors and low noise performance. The logic-controlled shutdown feature makes it suitable for systems requiring efficient standby modes. Consider the 50 mA output limit when sizing for load requirements, and ensure input voltage remains within the specified maximum rating to maintain regulation.

Part Context

This part belongs to the LD2980 series of ultra-low drop voltage regulators designed for low-noise and low-power applications. The series is characterized by its ability to work efficiently with modern low ESR ceramic capacitors, reducing board space and cost compared to older tantalum or aluminum electrolytic solutions. It serves as a PMIC solution for precise voltage regulation in compact electronic designs.
