LD2985AM36R

Overview

The LD2985AM36R is a fixed-output linear voltage regulator manufactured by STMicroelectronics, providing a stable 3.6V output with a maximum current capacity of 150mA. It operates within an input voltage range up to 16V and features a typical dropout voltage of 0.575V at full load. The device incorporates internal overcurrent and thermal protection mechanisms to ensure reliability under fault conditions. Designed for surface-mount applications in the SOT-23-5 package, it supports an operating temperature range from -40°C to +125°C. The regulator includes an enable control feature and exhibits a power supply rejection ratio of 45dB at 1kHz.

Feature Summary

Logic-controlled electronic shutdown function compatible with TTL levels
Internal protection against overcurrent and excessive temperature
Ultra-low quiescent current operation suitable for battery-powered systems

Applications

Cellular phones
Palmtop laptop computers
Personal digital assistants (PDA)
Camcorders and cameras

Procurement Notes

Verify component status as this part number is marked as obsolete or not recommended for new designs. Confirm availability through authorized distributors or secondary markets. Ensure replacement components meet identical electrical specifications and pinout compatibility. Check RoHS compliance status for environmental regulations. Validate datasheet revisions before integration into production schedules.

Selection Notes

Select based on required fixed output voltage of 3.6V and 150mA load capability. Consider the SOT-23-5 package constraints for PCB layout. Evaluate thermal performance given the 125°C maximum junction temperature limit. Verify that the application benefits from low noise characteristics and logic shutdown functionality. Compare against active replacements if long-term supply stability is required.

Part Context

This component belongs to the LD2985 family of ultra-low drop and low-noise voltage regulators. The series is characterized by very low dropout voltages and low quiescent currents, making it ideal for portable electronics. The AM36 suffix specifically denotes the 3.6V fixed output variant within this product line.
