Description
The STLQ50 is a BiCMOS linear
regulator specifically designed for operating in environment with very low power consumption constraints.
Due to the very low quiescent current (3 µA) the device is suitable for those application that have very long stand-by time allowing extension of battery life.
The P-MOS pass element allows also a very good drop-out figure (200 mV at 25 mA IO and 350 mV at full load) without affectin...
