Description

The STLQ015xx provides 150 mA of maximum

current from an input voltage ranging from 1.5 V

to 5.5 V, with a typical dropout voltage of 112 mV.

The key feature of this device is its quiescent

current, which is just 1.4 µA at maximum output

current. The device is stable with a ceramic

capacitor on the output. It offers very low

quiescent current, extending battery life and

making the device suitable for applications

requiring very long standby time. The enable logic

control function puts the STLQ015xx in shutdown

mode, reducing total current consumption to 1 nA.

The device also includes short-circuit constant-

current limiting and thermal protection. Typical

applications for the device are portable and

battery-powered systems, electronic sensors, and

microcontroller power supply.
