Introduction to MIC5335-SOYMT-TR

The MIC5335-SOYMT-TR is a highly integrated low quiescent current, high accuracy linear voltage regulator specifically designed for use in portable and battery-powered designs. As part of a Texas Instruments Analog and Power Management (APM) family, the MIC5335-SOYMT-TR combines the advantages of a precision voltage regulator and low-dropout (LDO) topology with low quiescent current in a very small 3-pin Surface-Mounted Device (SMD).

Application Field of MIC5335-SOYMT-TR

The MIC5335-SOYMT-TR is ideal for designs that require a regulated DC voltage from an input voltage as high as 24V with a very low supply current and high accuracy. Due to its wide input voltage range, the MIC5335-SOYMT-TR can be used for battery-powered systems such as medical and healthcare applications, consumer products, industrial monitoring, and IoT devices.The MIC5335-SOYMT-TR is suitable for applications such as automotive, consumer, industrial, and medical/healthcare, with performance characteristics that include High accuracy; Low dropout; High power supply rejection; Thermally enhanced surface mount package; Low input voltage range; Low quiescent current; and wide operating temperature range. Furthermore, the MIC5335-SOYMT-TR provides options for both single-input (fixed) and adjustable-output versions with a max output current of 3.2A.

Working Principle of MIC5335-SOYMT-TR

The MIC5335-SOYMT-TR is constructed using CMOS and BiCMOS technology coupled with its on-chip logic and 8-bit DAC feedback. This combination with the feedback from the 8-bit DAC helps to create a precise and regulated output voltage.The MIC5335-SOYMT-TR has two separate circuits: a linear regulator and a voltage reference. The linear regulator has two transistors, a PNP and an NPN. The PNP is used to monitor the output voltage, and the NPN monitors the input voltage. The output voltage is kept constant by comparing the voltage reference with the PNP transistor output voltage. If the output voltage is lower than the voltage reference, the PNP transistor will sink current from the output, increasing its voltage. If the output voltage is higher than the reference, the NPN transistor will sink current from the output, decreasing its voltage.The output voltage of the MIC5335-SOYMT-TR can be adjusted using the 8-bit DAC, which also provides feedback to the transistor monitors for better accuracy. This 8-bit DAC can be used to adjust the output voltage in the range of 0.3V up to 5.5V with a minimum step size of 0.1% of the output voltage.

Conclusion

The MIC5335-SOYMT-TR is a highly integrated linear voltage regulator specifically designed for application to portable and battery-powered designs. Its wide input voltage range, low quiescent current, high accuracy, and 8-bit DAC feedback make it an ideal solution for many applications, including automotive, consumer, industrial, and medical/healthcare applications. Additionally, it provides options for both single-input (fixed) and adjustable-output versions, with a max output current of 3.2A.
