LM1086IT-3.3/S4000135

Overview

The LM1086IT-3.3/S4000135 is a positive low dropout linear voltage regulator manufactured by Texas Instruments, belonging to the LM1086 series. It provides a fixed output voltage of 3.3 V with a maximum load current capability of 1.5 A. The device features a maximum dropout voltage of 1.5 V at full load and operates within an input voltage range up to 30 V. It utilizes a TO-220 three-pin package designed for through-hole mounting. The regulator supports an operating temperature range from -40 °C to +125 °C and includes internal thermal overload protection.

Feature Summary

Fixed 3.3 V output regulation with 1.5 A current capacity
Low dropout performance ensuring efficient voltage conversion
Integrated thermal overload protection for operational safety

Applications

General purpose power supply regulation
Battery-powered systems requiring stable voltage rails
Embedded circuit power conditioning

Procurement Notes

Verify the complete part number including the S4000135 suffix against official Texas Instruments documentation to confirm specific packaging or marking variations. Ensure compatibility with through-hole assembly processes given the TO-220 form factor. Cross-reference electrical specifications such as dropout voltage and thermal resistance with the latest datasheet to validate suitability for the target application environment.

Selection Notes

Select this component when a fixed 3.3 V rail is required with moderate current demands up to 1.5 A. The TO-220 package facilitates heat dissipation for higher power applications compared to surface-mount alternatives. Consider the 30 V maximum input rating and wide operating temperature range for robustness in industrial or automotive environments where thermal management is critical.

Part Context

This regulator is part of the LM1086 family, which shares pinout compatibility with industry-standard adjustable regulators like the LM317. The series is designed for applications requiring simple implementation and reliable performance. The IT designation indicates a specific temperature grade and package variant within the broader LM1086 product line offered by Texas Instruments.
