LD1086V33

Overview

The LD1086V33 is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 3.3 V output with a maximum load current of 1.5 A. The device features a line regulation of 6 mV and a load regulation of 10 mV, ensuring high precision within ±1% accuracy at 25 °C. It operates from an input voltage range up to 30 V and maintains functionality across a wide temperature spectrum from -40 °C to +125 °C. The component utilizes a TO-220 through-hole package with three pins and consumes a typical quiescent current of 5 mA.

Feature Summary

Fixed 3.3 V output voltage with tight tolerance for precise power supply applications
High current capability delivering up to 1.5 A with guaranteed low dropout performance
Integrated thermal protection and internal current limiting for robust operation under fault conditions

Applications

General-purpose power supply regulation in electronic circuits
Pre-regulation stages for switching power converters
Power management in embedded systems requiring stable 3.3 V rails

Procurement Notes

Verify the specific package variant, as the LD1086 series includes DPAK, D2PAK, and TO-220 options. Confirm that the fixed 3.3 V version matches the design requirement rather than the adjustable variant. Ensure the selected component meets the required thermal dissipation capabilities for the intended operating environment.

Selection Notes

Select this component when a fixed 3.3 V rail is required with high current capacity. The TO-220 package offers superior thermal performance compared to surface-mount alternatives, making it suitable for higher power dissipation scenarios. Verify input voltage constraints do not exceed the 30 V maximum rating.

Part Context

This part belongs to the LD1086 family of positive low-dropout regulators. The family includes both adjustable and fixed voltage versions available in multiple packages such as TO-220, D2PAK, and DFN8. The LD1086V33 specifically denotes the fixed 3.3 V output configuration in the TO-220 housing.
