The STLQ50 is a BiCMOS linear regulator specifically designed for operating in environments where very low power consumption is required.

Its very low quiescent current (3 μA) results in extended battery life, making the device suitable for applications which have very long standby time.

The PMOS pass element allows very good dropout values (200 mV at 25 mA IO and 350 mV at full load) without affecting the consumption characteristics.

Housed in the very small SOT323-5L, it meets space-saving requirements in battery-powered equipment.
