Overview
The LM1117DT-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 (DCY) surface-mount 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 current limiting and thermal shutdown mechanisms for robust operation under fault conditions
- Zener-trimmed bandgap reference ensures high output voltage accuracy within ±1% tolerance
- Low dropout characteristic allows efficient regulation with minimal input-to-output voltage differential
Applications
- AC drive power stage modules
- Merchant network and server PSU
- Industrial AC/DC converters
- Ultrasound scanners
- Servo drive control modules
Procurement Notes
Verify that the ordering suffix /NOPB confirms lead-free and RoHS compliance as specified in the datasheet. Confirm the DCY package designation corresponds to the required SOT-223 footprint for PCB layout compatibility. Ensure the standard LM1117 variant meets the 0°C to +125°C operating temperature requirements rather than the extended -40°C LM1117I grade.
Selection Notes
Select this component when a fixed 2.5 V rail is required with up to 800 mA capacity in a compact surface-mount form factor. Consider the 1.2 V dropout voltage to ensure sufficient headroom between input and output voltages across all operating loads. Verify that the application environment remains within the 0°C to +125°C junction temperature limits defined for the standard LM1117 series.
Part Context
This part belongs to the LM1117 family of 800-mA low-dropout linear regulators from Texas Instruments. The family offers both adjustable and fixed output versions in various packages including TO-220, TO-252, and WSON. The LM1117DT-2.5/NOPB specifically designates the fixed 2.5 V version in the SOT-223 package.
Replacement Considerations
The TLV1117 is documented as a newer drop-in alternative. For improved functionality in the same SOT-223 configuration, the TLV761 is recommended as a replacement option.
