The PJ75AL50SA is a Low Dropout Regulator (LDO) SOT-23 RoHS manufactured by Pingjingsemi. It offers adjustable voltage output from 1.2V to 5.0V and it includes a rich set of protection features such as current limit protection, short-circuit protection, thermal shutdown, and overvoltage protection. This device includes an internal P-channel MOSFET and can deliver up to 50mA of continuous output current. Its low source voltage range is from 1V to 6V which makes it suitable for battery-powered applications. The high PSRR and low dropout voltage make it an excellent choice for applications that require higher precision voltage regulation. The small SOT-23 package minimizes board size and increases heat dissipation. This part is RoHS compliant, making it an ideal solution for electronics equipment manufacturers that require RoHS compliance.
