What are the key features of STLQ015XG33R?
- Ultra-low 112 mV typical dropout voltage at 150 mA enables use with supply rails as low as 1.55 V, extending battery life in portable designs
- Fixed 3.3 V output in a compact SOT-666 6-pin flat-lead package occupying minimal PCB footprint for space-constrained IoT and wearable applications
- Wide input voltage range from 1.55 V to 5.5 V with 7 V absolute maximum rating provides compatibility with single-cell Li-ion, USB, and regulated bus supplies
What is STLQ015XG33R used for?
The STLQ015XG33R is well suited for powering microcontrollers, sensors, and RF modules in battery-operated IoT nodes and wearables where the 3.3 V rail must be maintained with minimal headroom from a Li-ion or LiPo cell. Its ultra-low dropout of 112 mV at 150 mA allows reliable regulation even as the battery approaches end-of-discharge. The tiny SOT-666 package makes it a practical choice for compact portable electronics and multi-rail PMU designs.

Frequently Asked Questions
What is the dropout voltage of STLQ015XG33R at full 150 mA load?
The STLQ015XG33R has a typical dropout voltage of 112 mV and a maximum dropout voltage of 300 mV at 150 mA output current. This ultra-low dropout allows the device to maintain a regulated 3.3 V output from input supplies as low as approximately 3.41 V typical, making it ideal for single-cell battery-powered designs.
Can STLQ015XG33R operate directly from a single-cell Li-ion battery throughout its discharge cycle?
Yes. With an input voltage range of 1.55 V to 5.5 V and a typical dropout of only 112 mV, the STLQ015XG33R can maintain 3.3 V regulation from a Li-ion cell down to approximately 3.41 V, covering most of the usable discharge range of a standard 3.6 V to 4.2 V Li-ion cell.
What package does STLQ015XG33R use, and how does its size compare to standard SOT-23 regulators?
The STLQ015XG33R is packaged in the SOT-666 6-pin flat-lead format, which has a smaller footprint than the standard SOT-23 3-pin package. The SOT-666 package measures approximately 1.6 mm x 1.6 mm, making it a better choice for miniaturized wearable and IoT PCB layouts where board area is at a premium.
Is STLQ015XG33R RoHS-compliant, and what is its JESD-609 classification?
Yes, the STLQ015XG33R carries a JESD-609 Code of e3, indicating it is RoHS-compliant and halogen-free. The device is qualified for lead-free solder processes with a maximum reflow temperature of 260 °C, suitable for modern environmentally compliant manufacturing lines.
