Overview
The STLQ015M30R, produced by STMicroelectronics, is an ultra-low quiescent current linear voltage regulator. This device is designed to provide 150 mA of maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 112 mV. The key feature of the STLQ015M30R is its very low quiescent current, which is just 1.4 µA at maximum output current, significantly extending the battery life of applications requiring long standby times. The regulator includes an enable logic control function that puts the device in shutdown mode, reducing total current consumption to 1 nA. It also features short-circuit constant-current limiting and thermal protection, making it suitable for a variety of battery-powered and portable applications.
