Overview
The LM1086ISX-1.8/NOPB is a fixed-output positive low-dropout linear regulator manufactured by Texas Instruments, delivering a stable 1.8 V output at up to 1.5 A load current. It operates within an input voltage range of 2.6 V to 27 V and features a typical dropout voltage of 1.3 V at full load. The device incorporates internal thermal shutdown and current limiting for robust protection. Designed for surface-mount applications, it utilizes the D2PAK (TO-263) package and supports operation across an extended temperature range from -40°C to +125°C.
Feature Summary
- Integrated thermal shutdown and current limiting circuitry for enhanced operational safety
- Low dropout voltage characteristic enabling efficient regulation with minimal input-to-output differential
- Fixed 1.8 V output configuration eliminates external resistor requirements for standard voltage setting
Applications
- Battery-powered portable electronic devices requiring efficient voltage regulation
- Post-regulation stages in switching power supply architectures
- Embedded systems utilizing 1.8 V logic levels or analog reference circuits
Procurement Notes
Verify the specific suffix 'ISX' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance standards as indicated by the NOPB designation. Cross-reference the datasheet revision date to validate parameter accuracy before final procurement decisions.
Selection Notes
Select this component when a fixed 1.8 V output is required with high current capability in a compact surface-mount form factor. Consider the 1.3 V typical dropout voltage relative to the minimum available input voltage to ensure proper regulation under all load conditions. Evaluate thermal dissipation requirements based on the D2PAK package's thermal resistance characteristics.
Part Context
This part belongs to the LM1086 family of 1.5 A low-dropout positive regulators. The ISX variant specifically denotes the surface-mount D2PAK package configuration with tape-and-reel delivery. It shares core electrical performance metrics with other LM1086 variants while differing primarily in physical packaging and shipping format.
Replacement Considerations
Direct substitutes include LM1086IS-1.8/NOPB for identical electrical performance in standard tube packaging. Verify pin compatibility and thermal characteristics when considering alternative manufacturers offering similar LDO specifications.
