LM1117MPX-3.3 NOPB 800-mA 15-V linear voltage regulator IC

It’s an LM1117MPX-3.3/NOPB 800-mA 15-V linear voltage regulator IC. The LM1117MPX-3.3/NOPB is a linear voltage regulator integrated circuit manufactured by Texas Instruments. It is a member of the LM1117 family of regulators, designed to provide a fixed output voltage of 3.3 volts. The LM1117MPX-3.3/NOPB is a low-dropout (LDO) regulator, meaning it can regulate the output voltage even when the input voltage is close to the desired output voltage. This makes it suitable for applications where the input voltage is not significantly higher than the desired output voltage. The IC provides thermal shutdown protection, which helps prevent damage from excessive heat. It also features built-in overcurrent and short-circuit protection, enhancing its reliability. The TO-252 (D-PAK) package is a widely used surface-mount package, allowing for easy integration onto printed circuit boards (PCBs) and providing good thermal dissipation.
