Overview
The LM1086IT-5.0 is a positive low dropout linear regulator from Texas Instruments, delivering up to 1.5A of output current with a fixed 5V output voltage. 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 incorporates internal thermal shutdown and current limiting for robust protection. It is housed in a TO-220 package suitable for through-hole mounting and supports an operating temperature range from -40°C to 125°C.
Feature Summary
- Integrated thermal shutdown and current limiting circuitry for enhanced reliability
- Fixed 5V output configuration eliminates external resistor requirements
- Low dropout performance enables efficient regulation with minimal input-output differential
Applications
- General-purpose power supply regulation
- Battery-powered equipment requiring stable voltage rails
- Embedded systems and microcontroller power distribution
Procurement Notes
Verify the specific suffix 'S5002153' against official Texas Instruments documentation to confirm its exact meaning regarding tape-and-reel packaging or special processing. Standard datasheets typically list 'NOPB' for lead-free versions. Ensure the procurement channel provides valid traceability and authenticity certificates matching the manufacturer's specifications.
Selection Notes
Select this component when a fixed 5V rail is required for loads up to 1.5A. The TO-220 package offers superior thermal dissipation compared to surface-mount alternatives. Consider the 1.3V dropout characteristic to ensure adequate headroom between input and output voltages under maximum load conditions.
Part Context
This part belongs to the LM1086 family of 1.5A low dropout regulators. It shares pinout compatibility with industry-standard adjustable regulators like the LM317, facilitating design flexibility. The series includes both adjustable and fixed voltage options, catering to diverse power management needs in industrial and consumer electronics.
Replacement Considerations
