STLQ015 150 mA, ultra low quiescent current linear voltage regulator Datasheet - production data 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. SOT23-5L Features • Input voltage from 1.5 to 5.5 V • Very low quiescent current: – 1.0 µA (typ.) at no load – 1.4 µA (typ.) at 150 mA load – 1 nA (typ.) in OFF mode – 200 nA max. in OFF mode at 125 °C • Output voltage tolerance: ± 2% at 25 °C Application • 150 mA guaranteed output current • Wide range of output voltages: 0.8 V to 3.3 V in 100 mV steps • Logic-controlled electronic shutdown • Mobile phones • Digital still cameras (DSC) • Battery-powered equipment • Portable media players • Compatible with ceramic capacitor (COUT = 1 µF) • Internal current and thermal limit • Temperature range: from -40 °C to 125 °C July 2015 This is information on a product in full production.

Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value. 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.
