LM1086CS-5.0/NOPB

Overview

The LM1086CS-5.0/NOPB is a fixed-output low dropout positive regulator from Texas Instruments, delivering a nominal 5.0V output with a maximum continuous current of 1.5A. It operates within an input voltage range of 2.6V to 30V and features a typical dropout voltage of 1.3V at full load. The device provides a power supply rejection ratio (PSRR) of 30dB at 100kHz and maintains an accuracy of 2%. Designed for robust performance, it supports an operating temperature range from -40°C to +125°C and utilizes a D2PAK-3 (TO-263-3) surface-mount package.

Feature Summary

Provides a fixed 5.0V regulated output suitable for standard logic and peripheral power rails
Capable of sourcing up to 1.5A of continuous output current for moderate power applications
Features integrated thermal overload and short-circuit protection for enhanced reliability

Applications

General-purpose linear regulation in industrial control systems
Power supply stages for embedded computing hardware
Biasing circuits for analog-to-digital converters and sensors

Procurement Notes

Verify the suffix 'NOPB' confirms lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the 'C' grade indicates the extended industrial temperature range of -40°C to +125°C. Ensure the 'S' designation matches the required TO-263-3 surface mount footprint for PCB layout compatibility.

Selection Notes

Select this component when a stable 5.0V rail is required with currents up to 1.5A. The low dropout characteristic allows operation with minimal input-to-output voltage differential, improving efficiency compared to standard regulators. Consider the thermal resistance of the D2PAK package and ensure adequate copper area on the PCB for heat dissipation under high-load conditions.

Part Context

This part belongs to the LM1086 family of 1.5A low dropout positive regulators. The series offers both adjustable and fixed output options, providing designers with flexibility for various voltage requirements. The LM1086 is widely used in applications requiring efficient linear regulation with high ripple rejection capabilities.
