Introducing the STLQ50, a BiCMOS linear regulator built for environments requiring ultra-low power consumption. With an extensive input range of 2.3 to 12V, it can provide a maximum output current of 50 mA while maintaining an incredibly low quiescent current of 3uA.
Thanks to the PMOS pass element, it achieves outstanding dropout values (200 mV at 25 mA IO and 350 mV at full load) without compromising consumption characteristics. Housed in the compact SOT323-5L package, it perfectly meets space-saving requirements in battery-powered equipment.
This circuit is a versatile solution for portable/battery-powered equipment, electronic sensors, microcontroller power, and real-time clock backup power applications.
