LD2985AM30R

Overview

The LD2985AM30R is a fixed-output low dropout linear voltage regulator manufactured by STMicroelectronics, providing a stable 3.0 V output with a maximum load current of 150 mA. It operates within an input voltage range of 2.5 V to 16 V and features a very low dropout voltage of 280 mV at full load. The device incorporates logic-controlled electronic shutdown via Pin 3 for power management and includes internal thermal and current limiting protections. Designed for battery-powered systems, it achieves ultra-low quiescent current consumption and supports external noise reduction through a bypass pin.

Feature Summary

Logic-controlled electronic shutdown function compatible with TTL levels
Ultra-low dropout voltage performance suitable for battery-powered applications
Internal protection against overcurrent and thermal overload conditions

Applications

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

Procurement Notes

Verify the specific suffix 'M30R' to confirm the 3.0 V fixed output variant. Ensure compatibility with SOT-23-5L surface mount packaging requirements. Confirm RoHS compliance status for environmental regulations. Validate that the supply chain source provides authentic STMicroelectronics components to avoid counterfeit risks in critical electronic assemblies.

Selection Notes

Select this component when a precise 3.0 V rail is required with minimal voltage drop under high load conditions. Consider its low quiescent current for extending battery life in portable devices. Evaluate the need for the inhibit pin functionality if system-level power management is necessary. Ensure the application environment stays within the specified -40 °C to 125 °C operating temperature range.

Part Context

This part belongs to the LD2985 family of low dropout regulators from STMicroelectronics. The series offers various fixed output voltages including 1.8 V, 2.5 V, 3.3 V, and 5.0 V. All variants share the same SOT-23-5L package and core architectural features, differing primarily in their regulated output voltage settings defined by the model suffix.
