LM1086ILDX-3.3/NOPB

Overview

The LM1086ILDX-3.3/NOPB is a fixed positive low dropout linear regulator manufactured by Texas Instruments, delivering a stable 3.3V output at up to 1.5A. It utilizes an LLP-8 package and supports input voltages up to 27V. The device features a typical dropout voltage of 1.3V at full load and maintains operation across a temperature range of -40°C to +125°C.

Feature Summary

Provides a fixed 3.3V regulated output for power supply applications
Supports high current delivery up to 1.5A with low dropout characteristics
Operates reliably within an extended industrial temperature range

Applications

Portable battery-powered equipment requiring efficient voltage regulation
Post-regulation circuits for switching power supplies
On-card regulation for distributed power architectures

Procurement Notes

Verify the specific suffix 'ILDX' corresponds to the LLP-8 package variant when sourcing. Confirm RoHS compliance status via the manufacturer datasheet. Ensure thermal management strategies align with the package's thermal resistance specifications for sustained 1.5A loads.

Selection Notes

Select this component when a fixed 3.3V rail is required with high current capability in a compact surface-mount footprint. Compare against adjustable variants if flexible output voltage is needed. Consider thermal dissipation requirements based on the input-output voltage differential and ambient conditions.

Part Context

This part belongs to the LM1086 family of 1.5A low dropout positive regulators. It shares core electrical performance with other package options like TO-263 and TO-220 but offers a smaller form factor suitable for dense PCB layouts. The NOPB suffix indicates lead-free construction compliant with environmental standards.
