ST offers fixed and adjustable output linear regulators featuring an optimal combination of low dropout voltage, quiescent current, transient response and low noise. They are ideal for battery-powered applications where both optimum heat dissipation and small dimensions are key factors.
STLQ015XX ultra-low quiescent current linear regulators
The STLQ015XX series of 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 STLQ015XX series is available in a wide range of output voltages, from 0.8 V to 3.3 V in 100 mV steps.
