Frequently Asked Questions
What is the output voltage and maximum output current of the LM1117IDTX-5.0/NOPB?
The LM1117IDTX-5.0/NOPB provides a fixed 5.0V output voltage with a maximum output current of 800mA. The typical dropout voltage is 1.2V (maximum 1.4V), meaning the input voltage must be at least 6.5V to maintain regulation.
What input voltage range does the LM1117IDTX-5.0/NOPB support?
The device supports an input voltage range from 6.5V minimum to 15V maximum, with an absolute maximum rating of 20V. Operating within the 6.5V–15V range ensures stable 5V output regulation and protects the internal circuitry.
Is the LM1117IDTX-5.0/NOPB RoHS compliant, and what package does it use?
Yes, the LM1117IDTX-5.0/NOPB is fully RoHS compliant (NOPB = No Lead). It comes in a SOT-223 surface-mount package, which offers good thermal dissipation via its exposed pad and is compatible with standard reflow soldering processes.
What protection features are built into the LM1117IDTX-5.0/NOPB?
The LM1117IDTX-5.0/NOPB includes internal current limiting to protect against short-circuit conditions and thermal shutdown to prevent damage from excessive junction temperature. These features make it a robust choice for unattended or industrial power supply applications.
