MIC5208-4.0YMM-TR Application Field and Working Principle

The MIC5208-4.0YMM-TR is a low-supply voltage, quiescent current, tiny, adjustable, low-dropout linear voltage regulator. This device is capable of supplying up to 1A of output current and can adjust an output voltage of 1.24V to 20V, providing a wide range of output voltages with an external resistor. The MIC5208-4.0YMM-TR is ideal for battery-powered applications, as its quiescent current is very low in active mode (1.5μA) and drops to 200nA in the shutdown mode. Its small package size of 2mmx2.1mm also makes it suitable for space-constrained applications.

The MIC5208-4.0YMM-TR is a linear regulator which works by using a simple series series-regulator circuit. The output voltage is set by connecting a resistor divider network between the output and the device’s reference pins. When the output voltage is lower than the reference voltage, the device’s pass element, (the P-channel FET) turns on and increases the output voltage. The series regulator loop ensures that the output voltage is always slightly higher than the reference voltage, allowing the device to maintain a stable output voltage.

The MIC5208-4.0YMM-TR also comes with a shutdown feature, which allows it to be powered down to a current draw as low as 200nA. When the shutdown pin is pulled low, the device enters a low-power state, reducing the quiescent current draw to a fraction of its active state draw.

The MIC5208-4.0YMM-TR is ideally suited for controlling output voltages in a wide range of battery-powered systems. The device’s low quiescent current draw and small package size make it an attractive option for space-constrained or battery-benefitted applications. Additionally, the device’s adjustable voltage and wide operating temperature range (-40°C to +85°C) make it suitable for use in both portable and industrial applications.

In conclusion, the MIC5208-4.0YMM-TR is a tiny, low-supply voltage, adjustable, low-dropout linear voltage regulator that is ideal for controlling output voltages in a wide range of battery-powered systems. Its low quiescent current, wide operating temperature range, and adjustable output voltage make it a viable solution for both portable and industrial applications.
