LM1086CT-5.0

Overview

The LM1086CT-5.0/NOPB is a positive linear regulator from the LM1086 family, manufactured by Texas Instruments. It provides a fixed 5V output with a maximum load current of 1.5A. The device operates within an input voltage range of 2.6V to 30V and features a typical dropout voltage of 1.3V at full load. It utilizes a TO-220-3 through-hole package and supports an operating temperature range from -40°C to +125°C. Internal protections include thermal shutdown and current limiting.

Feature Summary

• Provides a fixed regulated output voltage
• Supports high continuous load current up to 1.5A
• Integrates internal thermal overload protection
• Includes built-in current limiting for short-circuit safety

Applications

• General-purpose power supply regulation
• Pre-regulation for switching regulators
• Battery-powered equipment power conditioning
• Embedded system voltage rails

Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm the fixed 5.0V output specification. Ensure the NOPB designation aligns with RoHS compliance requirements. Confirm that the TO-220-3 package matches the target PCB footprint and thermal management strategy before finalizing procurement orders.

Selection Notes

Select this component when a stable 5V rail is required for loads up to 1.5A in through-hole designs. Consider the thermal resistance of the TO-220 package and ensure adequate heatsinking if the input-output differential voltage results in significant power dissipation. Verify that the minimum input voltage requirement is met under all operating conditions.

Part Context

This part belongs to the LM1086 series of 1.5A low-dropout positive regulators. The series includes both adjustable and fixed output variants. The 'CT' prefix indicates the specific TO-220-3 through-hole package configuration, while the '-5.0' designator specifies the fixed 5-volt output option within the product line.

Replacement Considerations

• LM1086IT-5.0/NOPB
• LM1086IS-5.0/NOPB
