IRU1050CT

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The IRU1050CT is a linear voltage regulator IC manufactured by Infineon Technologies, formerly International Rectifier. It provides a positive adjustable output with a maximum current capability of 5A. The device utilizes a TO-220AB package and supports an input voltage range up to 7V. It features internal protection mechanisms including overcurrent and thermal shutdown. The component operates within a temperature range of 0°C to 150°C junction temperature.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Provides stable positive adjustable voltage regulation
• Supports high output current up to 5A
• Includes integrated overcurrent and thermal protection

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• General purpose linear power supply circuits
• Battery-powered equipment requiring regulated voltage
• Industrial control systems needing reliable low-dropout regulation

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific package variant as the IRU1050 series includes multiple packages such as TO-220AB and UltraPak. Confirm RoHS compliance status as older revisions may not meet current standards. Check for obsolescence notices since the base part number is marked as obsolete in some distributor databases. Ensure the supplier provides genuine Infineon or International Rectifier branded units to avoid counterfeit components.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a robust 5A linear regulator is required for applications tolerant of higher power dissipation. Consider the thermal management requirements due to the linear topology. Compare against newer LDO alternatives if lower quiescent current or higher efficiency is critical. Verify that the input-output voltage differential remains within safe operating limits for the chosen load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the IRU1050 family of low dropout regulators originally developed by International Rectifier before its acquisition by Infineon. The family is designed for applications requiring high current capability with simple external adjustment. The CT suffix typically denotes the TO-220AB through-hole package variant, distinguishing it from surface-mount versions like the CP.
