LM1117MPX-50NOPB

Overview

The LM1117MPX-50NOPB is a positive fixed-output low-dropout linear regulator manufactured by onsemi. It provides a stable 5V output with a maximum current capacity of 800mA. The device features a maximum dropout voltage of 1.2V at full load and supports input voltages up to 20V. It incorporates internal overcurrent and thermal shutdown protection mechanisms. The component is housed in a SOT-223 surface-mount package, suitable for compact power management designs requiring precise voltage regulation.

Feature Summary

Provides a fixed 5V regulated output voltage
Delivers up to 800mA continuous load current
Includes integrated overcurrent and thermal shutdown protection
Operates with a maximum dropout voltage of 1.2V at rated current

Applications

General-purpose power supply regulation
Battery-powered systems requiring stable voltage rails
Embedded circuit power conditioning

Procurement Notes

Verify the manufacturer designation carefully, as the LM1117 series originates from Texas Instruments. Confirm that the specific part number corresponds to onsemi production if sourcing from this vendor. Ensure the suffix matches the required packaging configuration and verify RoHS compliance status against the latest datasheet documentation before procurement.

Selection Notes

Select this component when a fixed 5V rail is required with moderate current demands up to 800mA. Consider the SOT-223 package constraints for thermal dissipation under high load conditions. Verify that the input voltage does not exceed the 20V maximum rating. Ensure adequate heat sinking is provided if operating near the maximum current limit to maintain stability within the specified temperature range.

Part Context

This component belongs to the LM1117 family of low-dropout regulators. While originally developed by Texas Instruments, this specific variant is listed under onsemi distribution channels. It shares functional similarities with other fixed-voltage LDOs but is distinguished by its specific output voltage and current capabilities within the SOT-223 form factor.
