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.

This specification does not apply to output voltages below 1.5 V. (2)During shutdown and at no load, P-channel leakage current flowing through the internal resistor divider causes the VOUT rise. (3)Turn-on time is the time measured between the enable input just exceeding VEN high value and the output voltage just reaching 95% of its nominal value.
