Overview
The LM1086IT-5.0/NOPB is a fixed positive low-dropout linear regulator manufactured by Texas Instruments, delivering a nominal output voltage of 5V with a maximum continuous output current of 1.5A. It operates within an input voltage range of 2.6V to 27V and features a typical dropout voltage of 1.3V at full load. The device is housed in a TO-220-3 through-hole package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Provides stable 5V regulation for high-current applications up to 1.5A
- Operates effectively with minimal input-to-output voltage differential
- Includes internal thermal overload and short-circuit protection mechanisms
Applications
- General-purpose power supply circuits requiring regulated 5V rails
- Battery-powered systems utilizing low-dropout performance
- Embedded logic and peripheral power distribution networks
Procurement Notes
Verify the suffix NOPB indicates lead-free compliance and RoHS adherence per manufacturer specifications. Confirm the IT suffix corresponds to the specified industrial temperature grade (-40°C to +125°C) and TO-220 package variant. Cross-reference datasheet revision dates to ensure parameter consistency during sourcing.
Selection Notes
Select this component when a robust 1.5A capacity is required alongside a fixed 5V output. The TO-220 package facilitates efficient heat dissipation for sustained high-current loads. Ensure the input voltage remains within the 2.6V to 27V limits while accounting for the 1.3V dropout requirement under maximum load conditions.
Part Context
This part belongs to the LM1086 family of 1.5A low-dropout regulators, which offers both fixed and adjustable output options. The LM1086 series is designed for efficiency in battery-operated systems due to its low quiescent current and wide input voltage range, serving as a reliable solution for various linear regulation needs across industrial and consumer electronics.
