STMicroelectronics | STLQ50C18R

The STLQ50C18R 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 affecting the consumption characteristics.

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
• 200 mV dropout voltage at 25 mA output current
• Internal thermal protection
• Available in SOT323-5L package and SOT23-5L package (upon request)

Applications:

• Portable/battery powered equipmentsElectronic sensors
• Microcontroller power
• Real time clock backup power
