STLQ020, our LDO drops the mic
with fast response and 300 nA of quiescent current

STLQ020 Ultra-low consumption

STLQ020 series of 200 mA low-dropout voltage regulators has a quiescent current as low as 300 nA, without any compromise on performance. Thanks to a dedicated low power design and load-adaptive circuity, the STLQ020 offers much better dynamic behavior than other comparable LDOs on the market, such as higher PSRR (> 40 dB up to 200 kHz) and faster line/load transient response. It is the ideal companion to supply low-consumption microcontrollers, sensors and other small loads in space-constrained devices powered by coin or Li-Ion cells and working mainly in stand-by mode. The STLQ020’s tiny flip-chip-4 and DFN-6 packages can fit wellness monitors, medical sensors, and wireless IoT devices. The STLQ020 operates with an input voltage from 1.5 to 5.5 V, with a selection of output voltages from 0.8 to 4.5 V plus an adjustable version.

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.
