Description
SOT666
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.
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
