MIC37302WU-TR Application Field and Working Principle

The MIC37302WU-TR is a linear voltage regulator device (PMIC - Voltage Regulators – Linear) that offers low noise, ripple and output voltage variations, making it suitable for a variety of applications. It is a high-performance linear regulator that provides a regulated output with a minimum dropout. This device includes a discreet, low-noise shunt regulator at the output and utilizes a wide-range input voltage for stable operation.

Application

The MIC37302WU-TR is designed to be used in ATX, SFF and other low-noise applications. It is also suitable for automotive, industrial, medical and other applications with an input voltage of up to 28V and an output current up to 1.5 A. It can be used for powering DSP, FPGA and other digital ICs and components in various applications.

Features

The MIC37302WU-TR is available in a Small Outline package (SOP) that is 5mm wide and includes features such as: • Wide input voltage range up to 28V • Low dropout voltage • Internal 5mΩ current limiting • TTL compatible enable • Low noise and stable output

Working Principle

The MIC37302WU-TR is a low-dropout (LDO) linear regulator that operates by controlling the output voltage through an internal voltage reference (VREF). The output voltage is determined by the ratio of two resistors within the device. When the input voltage is greater than the output voltage then power is transferred from the input to the output. This is done by a pass element, MOSFET, within the small outline package. The output of the regulator is monitored by a shunt regulator that keeps the output voltage within specified limits. This shunt regulator permits for automatic temperature compensation of the output voltage to account for temperature variations. The shunt regulator compensates the voltage variation caused by temperature and load variations, allowing for a smooth, more stable output. The MIC37302WU-TR also has an internal over-current protection that limits its output current up to 1.5 A. For safety, the device has an enable pin (EN) which can be connected to an external signal in order to disable the regulator.

Conclusion

The MIC37302WU-TR is a high-performance linear voltage regulator (PMIC - Voltage Regulators – Linear) that provides a regulated output with low noise, low ripple and stable output voltage. This device has a wide-range input voltage and is suitable for automotive, industrial, medical, ATX, SFF and other applications. The MIC37302WU-TR also has an internal current-limit and thermal shut-down feature for safety. High-end linear Voltage Regulators are an essential part of any power supply design in order to provide a clean and stable output for various applications. The MIC37302WU-TR is a reliable and efficient LDO regulator that is capable of operating with a wide-range input voltage for both low and high load applications.
