Description
The STLQ015 provides 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 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 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 1 nA. 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 supply.
