Overview
The LM1117MPX-5.0/NOPB is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, providing a stable 5 V output with a maximum load current of 800 mA. It operates within an input voltage range up to 15 V and features a typical dropout voltage of 1.2 V at full load. The device incorporates internal current limiting and thermal shutdown protection mechanisms. It 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 circuit protection
- Zener-trimmed bandgap reference ensures precise output voltage regulation
- Low dropout voltage capability maintains regulation under minimal input-output differentials
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 the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's datasheet. Confirm the package designation matches the required SOT-223 footprint for PCB layout compatibility. Ensure the operating temperature range aligns with system requirements, noting that standard LM1117 variants may differ from industrial grade options.
Selection Notes
Select this component when a fixed 5 V rail is required with moderate current demands up to 800 mA. Consider the thermal resistance characteristics of the SOT-223 package for heat dissipation planning. Evaluate the need for external output capacitors to maintain stability and transient response performance according to application guidelines.
Part Context
This part belongs to the LM1117 family of low-dropout linear regulators designed for general-purpose power management applications. The series offers both adjustable and fixed voltage versions across various packages including TO-220, TO-252, and WSON. The LM1117MPX-5.0/NOPB specifically denotes the fixed 5 V variant in tape-and-reel packaging.
Replacement Considerations
The TLV1117 is identified as a newer drop-in alternative. For improved functionality in fixed output SOT-223 configurations, the TLV761 is recommended as a replacement option.
