The STLQ020PUR is an LDO regulator manufactured by STMicroelectronics, and is designed for a wide range of applications. It has a wide-range input voltage of 0.8V to 4.5V and an output current capability of 0.2A. The four-pin flip-chip T/R (transmitter/receiver) package design allows for easy installation and dual-mode operation, making it well-suited for multi-rail and high current applications. The LDO regulator also features low dropout voltage (LDO), low power consumption, and high PSRR (power supply rejection ratio). Additionally, it is AEC-Q100 qualified and RoHS compliant, making it suitable for automotive applications.
