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.

Notes:
(1)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.
