LM1117MPX-2.5/NOPB

Overview

The LM1117MPX-2.5/NOPB is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a stable 2.5 V output with a maximum load current of 800 mA. It utilizes the SOT-223 package and operates within a junction temperature range of 0°C to +125°C. The device features a typical dropout voltage of 1.2 V at full load and includes internal current limiting and thermal shutdown protection.

Feature Summary

• Integrated Zener-trimmed bandgap reference ensures high output voltage accuracy
• Built-in current limiting and thermal shutdown mechanisms protect against overload conditions
• Designed for improved transient response and stability when paired with tantalum output capacitors

Applications

• AC drive power stage modules
• Merchant network and server PSU
• Industrial AC/DC power supplies
• Ultrasound scanners
• Servo drive control modules

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement decisions. Ensure the component meets all environmental specifications for the intended deployment environment.

Selection Notes

Select this component when a fixed 2.5 V rail is required with up to 800 mA capacity in a surface-mount configuration. Consider the thermal resistance characteristics of the SOT-223 package during design to ensure adequate heat dissipation under maximum load conditions without external heatsinking.

Part Context

This part belongs to the LM1117 family of low-dropout regulators, which also includes adjustable versions and other fixed voltage options. The 'MP' designation indicates the SOT-223 surface-mount package variant, while 'NOPB' signifies lead-free construction compliant with RoHS standards.

Replacement Considerations
