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.
