The PJ75AL36SQ Low Dropout Regulator (LDO) SOT-89 RoHS manufactured by Pingjingsemi is an electronic device used to maintain a constant, low voltage output due to its low voltage dropout characteristics. It provides efficient and reliable output power supply regulation and is a very cost effective solution for high current applications, such as powering microprocessors, computers, tablets, smartphones, gaming consoles, and much more. The LDO is RoHS compliant and is designed to operate over a wide range of ambient temperatures. It features a temperature range of -20C to +105C. Its ultra-low dropout voltage characteristics (less than 300mV) enable stable regulation from a low voltage input source. Additionally, its high peak output current of 4 Amps makes it suitable for driving high power devices. It is packaged in the SOT-89 package, which makes it easy to install and mount on a printed circuit board.
