STLQ020PU28R - Low Drop Voltage Regulator

The STLQ020PU28R is a highly efficient, low drop voltage regulator designed and manufactured by STMicroelectronics, a leader in semiconductor solutions. This regulator is part of the STLQ020 series, which is known for its ultra-low quiescent current, making it an ideal choice for battery-powered applications where extending battery life is crucial.

With an output voltage of 2.8V, the STLQ020PU28R can deliver up to 200 mA of continuous current, which is suitable for a wide range of low-power devices. The device operates over a wide input voltage range from 2.5V to 5.5V, providing flexibility in various power supply configurations. This makes it compatible with most common battery technologies, including Li-ion, NiCd, NiMH, and alkaline cells.

The STLQ020PU28R boasts an ultra-low dropout of just 250 mV at maximum load, which enhances its efficiency and allows it to maintain a stable output even when the input voltage is close to the output voltage. This feature is particularly important for portable devices that experience fluctuating power levels.

One of the standout features of this voltage regulator is its ultra-low quiescent current of just 0.3 µA in no-load condition and 2 µA in light-load condition. This significantly reduces power consumption when the device is in standby mode, thus preserving battery life in applications such as wearables, IoT devices, and portable medical equipment.

The STLQ020PU28R is designed with thermal protection and short-circuit protection, ensuring the safety and reliability of the devices it powers. The regulator is available in a compact 4-bump flip-chip package, which minimizes the footprint on the PCB and is ideal for space-constrained applications.

In summary, the STLQ020PU28R from STMicroelectronics is a high-performance, low drop voltage regulator that offers excellent efficiency, ultra-low power consumption, and robust protection features. It is a perfect choice for designers looking to optimize power management in their next-generation portable and wearable devices.
