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.
