Description
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
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
Compatible with ceramic capacitor
(C
OUT
= 1 µF)
Internal current and thermal limit
Temperature range: from -40 °C to 125 °C
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.
