Frequently Asked Questions

What is the output voltage and maximum current of the LM1117MPX-5.0?

The LM1117MPX-5.0 provides a fixed 5V output voltage with ±1% accuracy and supports a maximum output current of 800mA (0.8A), making it suitable for powering microcontrollers, sensors, and other low-to-medium current loads.

What input voltage range does the LM1117MPX-5.0 support?

The LM1117MPX-5.0 requires a minimum input voltage of 6.5V and supports up to 15V (absolute maximum 20V). The typical dropout voltage is 1.2V, with a maximum of 1.3V, so a minimum input of approximately 6.3V is needed to maintain regulation at 5V output.

What package does the LM1117MPX-5.0 use and is it RoHS compliant?

The LM1117MPX-5.0 is housed in a SOT-223-3 (3-pin) package, which provides good thermal performance for surface-mount applications. Note that this specific variant is marked as Pb-free code 'No,' so verify RoHS compliance requirements against your application's regulatory needs before ordering.

What are typical applications for the LM1117MPX-5.0?

Typical applications include 5V power rails for microcontroller boards (Arduino, STM32, ESP32), IoT sensor nodes, set-top box power supplies, USB hub regulators, industrial control logic supplies, and any embedded system needing a stable 5V from a 7V–15V source.
