STMicroelectronics STLQ015 Current Linear Voltage Regulators

STMicroelectronics STLQ015 Current Linear Voltage Regulators provide 150mA of maximum current with an input voltage range from 1.5V to 5.5V and a typical dropout voltage of 112mV. The key feature of this device is its quiescent current, which is 1.4μA at maximum output current. The device is stable with a ceramic capacitor on the output.

The STLQ015 offers very low quiescent current and extends battery-life of applications requiring very long standby time. The enable logic control function puts the STLQ015 in shutdown mode, reducing total current consumption to 1nA. The device also includes short-circuit constant-current limiting and thermal protection. Typical applications are portable and battery-powered systems, electronic sensors, and microcontroller power supplies.
