Part Description: 50 mA, 3 µA supply current low drop linear regulator

Part Details:

STLQ50XX 50 mA, 3 µA supply current low drop linear regulator Features 2.3 V to 12 V input voltage range 50 mA maximum output current 3 µA quiescent current Available in 1.8 V, 2.5 V, 3.3 V, 5.0 V and adjustable SOT23-5L SOT323-5L (available on request) 200 mV dropout voltage at 25 mA output current Internal thermal protection Description Available in SOT323-5L package, and SOT23- 5L package (upon request) The STLQ50 is a BiCMOS linear regulator specifically designed for operating in environment Applications with very low power consumption constraints. Due to the very low quiescent current (3 µA) the Portable/battery powered equipments device is suitable for those application that have Electronic sensors very long stand-by time allowing extension of Microcontroller power battery life. Real time clock backup power 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 affecting the consumption characteristics. Housed in the very small SOT323-5L or SOT23-5L, it fulfils the space saving requirements in battery powered equipments. Table 1.
