Overview
The STLQ015XG33R, produced by STMicroelectronics, is an ultra-low quiescent current linear voltage regulator. This device is designed to provide a maximum current of 150 mA with an input voltage range from 1.5 V to 5.5 V. It features a typical dropout voltage of 112 mV and is particularly notable for its very low quiescent current, which is 1.0 µA at no load and 1.4 µA at 150 mA load. The regulator is stable with a ceramic capacitor on the output and includes logic-controlled electronic shutdown, short-circuit constant-current limiting, and thermal protection. These features make it ideal for applications requiring long standby times and low power consumption.
