LM1117MP-1.8

Overview

The LM1117MP-1.8 is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a stable 1.8 V output with a maximum load current of 800 mA. It operates within a junction temperature range of 0°C to 125°C and features a typical dropout voltage of 1.2 V at full load. The device incorporates internal current limiting and thermal shutdown protection mechanisms. Its circuit utilizes a Zener-trimmed bandgap reference to ensure output voltage accuracy within ±1%. The component is housed in a space-saving SOT-223 package.

Feature Summary

Integrated current limiting and thermal shutdown for robust operation under fault conditions
Zener-trimmed bandgap reference ensures high output voltage accuracy
Low dropout voltage capability allows efficient regulation with minimal input-to-output differential

Applications

Post regulator for switching DC-DC converters
Battery chargers
Portable instrumentation power supplies

Procurement Notes

Verify the specific suffix 'MP' corresponds to the SOT-223 package variant when sourcing. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance if required by your assembly specifications. Ensure the operating environment remains within the specified 0°C to 125°C junction temperature range for optimal performance.

Selection Notes

Select this component when a fixed 1.8 V rail is required with up to 800 mA capacity. It is suitable for applications where space constraints favor the SOT-223 package over larger TO-220 or TO-263 options. Consider the thermal resistance characteristics of the SOT-223 package when designing heat dissipation strategies for high-load scenarios.

Part Context

This part belongs to the LM1117 family of 800 mA low-dropout linear regulators from Texas Instruments. The family includes adjustable versions and other fixed voltages such as 2.5 V, 3.3 V, and 5.0 V. The LM1117 series is designed to replace standard 78xx regulators in many applications due to its lower dropout voltage and improved line/load regulation characteristics.
