LD2982AM18R

Overview

The LD2982AM18R is a linear voltage regulator manufactured by STMicroelectronics, providing a fixed 1.8V output with a 50mA current capacity. It features very low dropout voltage and low noise characteristics, designed for use with low ESR capacitors. The device includes an inhibit function to control power states efficiently.

Feature Summary

Ultra-low dropout voltage operation
Low noise performance suitable for sensitive circuits
Integrated inhibit function for power management

Applications

Low noise analog circuit power supplies
Portable battery-powered devices
Signal conditioning modules

Procurement Notes

Verify component authenticity as the LD2982AM18R is obsolete and no longer manufactured. Confirm availability of qualified substitutes such as the LD2980CM18TR if sourcing new production units is not possible. Ensure datasheet revisions match design requirements before procurement.

Selection Notes

Select this component for applications requiring a stable 1.8V rail with minimal ripple. Consider the 50mA limit for load requirements. Due to obsolescence, evaluate alternative regulators with similar pinouts and electrical specifications for long-term supply chain stability.

Part Context

This part belongs to the LD2982 series of low-dropout linear regulators from STMicroelectronics. These regulators are designed for efficiency in portable electronics, offering high power supply rejection ratios and stability with small ceramic capacitors.

Replacement Considerations

The LD2980CM18TR is listed as a similar substitute. Verify pin compatibility and electrical parameters against the original datasheet before substitution.
