Applications
The LP2986IM-3.3 is widely used in portable and battery-operated electronics such as smartphones, wearables, and IoT sensor nodes where ultra-low quiescent current extends battery life. It is also well-suited for post-regulation in industrial power supplies, automotive infotainment systems, and microcontroller supply rails requiring a stable 3.3V with minimal voltage overhead. Its combination of low dropout and low IQ makes it an excellent choice for always-on subsystems that must maintain tight voltage regulation under light-load conditions.

Frequently Asked Questions
What is the output voltage and current rating of the LP2986IM-3.3?
The LP2986IM-3.3 provides a fixed 3.3V output voltage with ±1% accuracy and can supply up to 150mA of continuous output current, making it suitable for a wide range of low-power digital and analog loads.
How low is the dropout voltage of the LP2986IM-3.3?
The LP2986IM-3.3 features a typical dropout voltage of only 200mV at 150mA load, allowing it to regulate 3.3V from input supplies as low as 3.5V, which is particularly advantageous in single-cell Li-ion battery applications nearing end of charge.
What is the quiescent current of the LP2986IM-3.3 and why does it matter?
The LP2986IM-3.3 has an ultra-low quiescent current of approximately 55µA, which significantly reduces static power consumption. This makes the device ideal for always-on circuits in battery-powered products such as IoT nodes, GPS trackers, and wearables where standby power is critical.
What package options are available for the LP2986IM-3.3?
The LP2986IM-3.3 is available in a compact SOT-23-5 package and an SO-8 package. The SOT-23-5 footprint is especially popular for space-constrained PCB designs in portable consumer and industrial electronics.
What are common applications for the LP2986IM-3.3?
Common applications include microcontroller supply rails, sensor node power supplies, portable consumer electronics, automotive infotainment subsystems, wireless communication modules, and any design needing a clean, stable 3.3V rail with minimal power loss.
