LF18CDT-TRY

Overview

The LF18CDT-TRY is a fixed-output linear low-dropout regulator manufactured by STMicroelectronics, providing a stable 1.8V output with a maximum continuous current of 500mA. It operates within an input voltage range of -0.5V to 40V and features a typical dropout voltage of 0.45V at rated load. The device incorporates internal overcurrent protection and thermal shutdown mechanisms to ensure operational safety under fault conditions. Designed for surface-mount installation, it utilizes the DPAK (TO-252-3) package configuration.

Feature Summary

Provides a fixed 1.8V regulated output suitable for low-noise applications
Features very low dropout voltage characteristics for efficient power management
Includes integrated overcurrent limiting and thermal overload protection

Applications

Battery-powered electronic systems requiring extended runtime
Low-power consumer electronics circuits
Noise-sensitive analog signal conditioning stages

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt as the device utilizes surface-mount technology. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference datasheet revisions to confirm pinout compatibility during integration.

Selection Notes

Select this component when a fixed 1.8V rail is required with moderate current demands up to 500mA. The low quiescent current makes it appropriate for battery-operated designs where efficiency is critical. Verify that the input voltage remains within the specified limits to maintain regulation without excessive heat dissipation in the DPAK package.

Part Context

This part belongs to the LFxx series of ultra-low drop regulators from STMicroelectronics. The series offers various fixed output voltages optimized for portable devices. The LF18 variant specifically targets applications needing precise 1.8V supply rails with minimal voltage headroom requirements.
