LD2980CM36TR

Overview

The LD2980CM36TR is a positive fixed-output low-dropout (LDO) linear voltage regulator manufactured by STMicroelectronics. It provides a stable 3.6V output with a maximum load current of 50mA. The device utilizes an SOT-23-5 surface-mount package and operates within an extended temperature range of -40°C to +125°C. Designed for compatibility with low equivalent series resistance (ESR) ceramic capacitors, it features ultra-low quiescent current consumption and internal protection mechanisms against overcurrent and thermal overload.

Feature Summary

Ultra-low dropout voltage performance optimized for battery-powered systems
Logic-controlled electronic shutdown function via inhibit pin
Stable operation guaranteed with low ESR ceramic output capacitors
Integrated overcurrent and thermal limit protection

Applications

Battery-powered instrumentation systems
Low noise power supply stages in audio equipment
Industrial control board local regulation
Switching mode power supply post-regulation

Procurement Notes

Verify the specific output voltage tolerance and package marking against the official datasheet before integration. Confirm that the selected output capacitor meets the low ESR requirements specified for stability. Ensure the operating environment remains within the defined temperature limits. Cross-reference the manufacturer part number to avoid confusion with similar variants in the LD2980 family.

Selection Notes

Select this component when a fixed 3.6V rail is required with minimal voltage drop under light loads. It is suitable for designs prioritizing low static current consumption and standby power reduction. The SOT-23-5 footprint offers space efficiency for compact portable electronics. Consider the logic-level compatibility of the shutdown pin if interfacing with standard TTL or CMOS control signals.

Part Context

This device belongs to the LD2980 family of ultra-low drop voltage regulators from STMicroelectronics. The family shares common architectural features such as low quiescent current and ceramic capacitor stability. Variants within the series differ primarily in their fixed output voltage options and specific package configurations. This model represents one of the fixed-voltage iterations designed for general-purpose low-power regulation tasks.
