The PJ73AL33SC is a Low Dropout Regulator (LDO) SOT-23-3 RoHS manufactured by Pingjingsemi. It is a 3-terminal voltage regulator, capable of supplying 300mA of continuous output current with excellent load and line regulation of 0.2% and 0.001%, respectively. The device has an operating voltage range of 2.3V to 5.5V, offering an output voltage accuracy of 1.25V to 3.3V with a 2% tolerance. It also features a low quiescent current of 11µA and a maximum dropout voltage of 1V at full load. The device is extremely stable, with a tolerance of ±2% over line, load, and temperature, and an excellent PSRR of 77dB at 1kHz. Furthermore, it is also designed for applications with noise-sensitive devices, with a very low noise output of 15µV P-P. The PJ73AL33SC is ideal for use in all kinds of consumer electronic devices, power management, automotive, and industrial products.
