STLQ015 150 mA, ultra low quiescent current linear voltage regulator Datasheet - production data Application Mobile phones Digital still cameras (DSC) Battery-powered equipment Portable media players Description Features Input voltage from 1.5 to 5.5 V Very low quiescent current: 1.0 A (typ.) at no load 1.4 A (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 (COUT = 1 F) Internal current and thermal limit Temperature range: from -40 C to 125 C September 2016 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 A 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 V OUT 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. 8/17 DocID17285 Rev 6 STLQ015 6 Typical performance characteristics Typical performance characteristics Figure 4: Output voltage vs temperature Figure 5: Output voltage vs input voltage (VOUT = 0.8 V) Figure 6: Output voltage vs input voltage (VOUT = 3.3 V) Figure 7: Dropout voltage vs temperature DocID17285 Rev 6 9/17 Typical performance characteristics STLQ015 Figure 8: Dropout voltage vs temperature Figure 9: Quiescent current vs temperature Figure 10: Supply voltage rejection vs frequency Figure 11: Supply voltage rejection vs IOUT Figure 12: Quiescent current vs input voltage Figure 13: Quiescent current vs output current 10/17 DocID17285 Rev 6 STLQ015 Typical performance characteristics Figure 14: Output noise voltage vs frequency Figure 15: COUT stability region Figure 16: Start-up transient Figure 17: Enable transient DocID17285 Rev 6 11/17 Package information 7 STLQ015 Package information In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK(R) packages, depending on their level of environmental compliance.
