Working Principle

The MIC37120-1.8YMT-TR is a low drop-out (LDO) linear voltage regulator, meaning that it works on a principle of adjusting the output voltage by adjusting the series resistor between the input voltage and the output voltage. The device is designed to reduce output voltage noise, minimize power wastage in compact applications, and reduce power-supply ripple and voltage undershooting.

The MIC37120-1.8YMT-TR works by regulating an input voltage to a stable and precise output voltage through the use of a negative feedback loop. When an over- voltage occurs, the device will draw current from the output, reduce the voltage and return the output voltage to its desired level. When an under-voltage occurs, the device will increase the output voltage until the desired level is achieved.

The device has an operating temperature range of -40°C to +125°C. It is also designed to meet the auto-zero segment-and-hold circuit requirement, enabling it to provide high accuracy voltage regulation even with rapidly changing input voltages. It also features a high accuracy of 0.5%, allowing precise voltage levels to be maintained.

The MIC37120-1.8YMT-TR is a highly reliable and efficient device, and is ideal for low noise and low power applications. With its wide input voltage range and fast transient response, it provides excellent power savings in applications requiring precise voltage regulation.
