Overview
The LM1117MP-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 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 surface-mount SOT-223 package with four pins.
Feature Summary
- Provides a fixed positive 2.5 V output voltage with high precision regulation.
- Integrates internal current limiting and thermal shutdown for robust circuit protection.
- Utilizes a Zener-trimmed bandgap reference to maintain tight output voltage accuracy.
Applications
- AC drive power stage modules
- Merchant network and server PSU
- Industrial AC/DC power supplies
Procurement Notes
Verify the specific suffix 'MP' against the manufacturer's official documentation to confirm the exact temperature grade and package variant. Ensure the ordering information matches the required operational temperature range and physical dimensions before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 2.5 V rail is required with moderate current capabilities. Consider the thermal resistance characteristics of the SOT-223 package relative to the expected power dissipation. Verify that the input voltage headroom meets the minimum dropout requirements across the entire operating temperature range.
Part Context
This part belongs to the LM1117 family of low-dropout regulators from Texas Instruments. The series offers various fixed voltage options and adjustable configurations. The LM1117MP variant specifically denotes the industrial temperature grade and surface-mount packaging configuration within the broader product line.
Replacement Considerations
The TLV1117 is identified as a newer drop-in alternative. For improved functionality in fixed output SOT-223 packages, the TLV761 is suggested as a replacement option.
