LDK320ADU120R

Overview

The LDK320ADU120R is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a nominal output voltage of 12 V with a maximum output current capability of 200 mA. The device operates within an input voltage range of 2.5 V to 18 V and features a typical dropout voltage of 100 mV at a 100 mA load. It incorporates a logic-controlled enable pin for electronic shutdown, reducing quiescent current to less than 1 μA in the off state. The component includes integrated short-circuit current limiting, thermal protection, and safe operating area safeguards.

Feature Summary

Logic-controlled electronic shutdown function enables deep sleep mode with minimal power consumption
Integrated protections against short circuits, thermal overload, and safe operating area violations
Compatible with ceramic output capacitors for stable operation

Applications

Digital Set-Top Boxes (DSC)
Television systems
Blu-ray and DVD players
Personal computers
Industrial equipment

Procurement Notes

Verify that the specific part number suffix corresponds to the required package type and tolerance grade. Confirm the ordering suffix matches the intended manufacturing configuration before procurement. Ensure compatibility with the target PCB footprint and verify environmental compliance status through official manufacturer documentation.

Selection Notes

Select this component when a fixed 12 V rail is required from a supply ranging between 2.5 V and 18 V. The device is suitable for applications requiring low noise and high power supply rejection ratio. Consider the SOT-89 package for surface mount assembly where thermal dissipation characteristics align with the system design constraints.

Part Context

This component belongs to the LDK320 family of low-dropout regulators designed for battery-powered and general-purpose electronics. The series offers various fixed output voltages and adjustable versions. The 'A' designation indicates a tighter output voltage tolerance compared to standard variants, ensuring higher precision for sensitive analog or digital loads.
