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.

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.
