ST’s series of low quiescent current LDO regulators is ideal for portable consumer and battery-powered applications where they extend the application’s battery lifetime and keep good dynamic performance, all in a small footprint. Package options include the SC70, SOT666, CSP 4 bumps and DFN from 1x1mm2.

STLQ015 ultra-low quiescent current linear regulators

The  STLQ015 ultra-low consumption LDOs provide up to 150 mA current from an input voltage ranging from 1.5 to 5.5 V. They feature a quiescent current of just 1.4 μA at the maximum load and a standby current of typically 1 nA, extending the battery lifetime in those applications requiring very long standby time. Requiring only two small external capacitors, they provide a cost-effective and space-saving solution for powering microcontrollers in portable and battery-powered systems, electronic sensors, home medical instruments and portable entertainment gadgets. The STLQ015 series is available in a wide range of output voltages, from 0.8 V to 3.3 V in 100 mV steps.
