Overview
The STLQ015XG15R, produced by STMicroelectronics, is a 150 mA ultra-low quiescent current linear voltage regulator. This device is designed to provide high efficiency and long battery life in various portable and battery-powered applications. It operates with an input voltage range from 1.5 V to 5.5 V and offers a wide range of output voltages from 0.8 V to 3.3 V in 100 mV steps. The STLQ015XG15R is notable for its very low quiescent current, which is typically 1.0 µA at no load and 1.4 µA at 150 mA load, significantly extending the battery life of devices. It also features logic-controlled electronic shutdown, internal current and thermal limiting, and compatibility with ceramic capacitors.
