LD1117DT18CTR

Overview

The LD1117DT18CTR is a positive fixed-output low-dropout linear regulator manufactured by STMicroelectronics. It provides a stable 1.8V output with a maximum current capacity of 800mA. The device operates within an input voltage range up to 15V and features a typical dropout voltage of 1.3V at full load. It incorporates internal thermal overload and short-circuit protection mechanisms. The component is housed in a surface-mount DPAK (TO-252-3) package, suitable for industrial applications operating between -40°C and +125°C.

Feature Summary

Integrated thermal overload and short-circuit protection for enhanced reliability
Low dropout voltage capability for efficient power management
Fixed 1.8V output configuration ensuring precise voltage regulation

Applications

Battery-powered systems requiring stable low-voltage rails
Portable consumer electronics and communication devices
Embedded systems needing clean power supply for sensitive components

Procurement Notes

Verify the complete part number including the CTR suffix to confirm the specific DPAK packaging and tape-and-reel quantity. Ensure compatibility with the target PCB footprint for TO-252-3 packages. Confirm that the application's thermal requirements align with the device's power dissipation capabilities in the chosen enclosure environment.

Selection Notes

Select this component when a fixed 1.8V rail is required with moderate current demands up to 800mA. It is suitable for designs where input voltages are moderately higher than the output, leveraging its low-dropout characteristic. Consider the DPAK package for its balance of thermal performance and surface-mount convenience compared to smaller SOT packages.

Part Context

This part belongs to the LD1117 series of low-dropout regulators from STMicroelectronics. The series offers various fixed and adjustable output voltages. The DT18 variant specifically targets the 1.8V market segment, commonly used in digital logic and microcontroller power supplies. The DPAK package allows for better heat dissipation than smaller surface-mount options.
