SGM2036-2.8YN5G/TR 300mA, Low Power and Low Dropout RF Linear Regulator

Overview of SGM2036-2.8YN5G/TR

The SGM2036-2.8YN5G/TR is a high-performance low-dropout (LDO) voltage regulator developed by SGMICRO, designed to provide a stable output of 2.8V. With a maximum output current of up to 500mA, the SGM2036 is optimal for powering analog and digital circuits that require precise voltage regulation. Its compact design and low quiescent current make it especially suitable for battery-powered applications, promoting energy efficiency and reliability.

Comparison with TPS79328DBVR

In contrast to the SGM2036-2.8YN5G/TR, the TPS79328DBVR from Texas Instruments also offers a 2.8V output, but there are several performance differences to consider. One notable advantage of the SGM2036 is its lower dropout voltage, which is rated at 150mV at 500mA load conditions. The TPS79328DBVR, on the other hand, has a dropout voltage that can reach up to 200mV. This lower dropout performance of the SGM2036 allows for better efficiency and voltage stability in critical operating conditions.

Quiescent Current Efficiency

Another key advantage of the SGM2036-2.8YN5G/TR lies in its quiescent current performance. With a quiescent current of just 1µA, the SGM2036 is tailored for ultra-low power applications, significantly extending battery life in portable devices. In contrast, the TPS79328DBVR exhibits a higher quiescent current of approximately 4.5µA. This difference in quiescent current translates to improved energy efficiency, making the SGM2036 a more attractive option for designers focusing on power-sensitive applications.

Thermal Performance and Protection Features

Thermal performance and protection features are critical in LDO design. The SGM2036-2.8YN5G/TR comes equipped with advanced thermal shutdown capabilities, activating at lower junction temperatures to safeguard the device and connected components from overheating. While the TPS79328DBVR also offers thermal protection, the proactive measures in the SGM2036 may lead to enhanced reliability in challenging environments, ensuring consistent performance during high-temperature operation.

Output Noise Performance

Output noise is another important consideration for designers working with sensitive analog circuits. The SGM2036-2.8YN5G/TR boasts low output noise, typically around 30µVRMS from 10Hz to 100kHz, which is ideal for applications that demand high fidelity, such as audio and RF systems. Conversely, the TPS79328DBVR generally exhibits higher output noise levels, which could be detrimental in noise-critical applications. The superior noise performance of the SGM2036 reinforces its suitability for high-precision circuits.

Conclusion

In summary, while both the SGM2036-2.8YN5G/TR and TPS79328DBVR serve as reliable low-dropout voltage regulators for 2.8V applications, the SGM2036 clearly demonstrates several competitive advantages. With a lower dropout voltage, minimal quiescent current, effective thermal protection, and reduced output noise, the SGM2036-2.8YN5G/TR is designed to meet the demanding needs of modern electronic applications. By choosing the SGM2036, designers can achieve greater efficiency, safety, and overall performance in their power management solutions.
