The MIC37501-1.5BR TR is a Linear Voltage Regulator from the Power Management IC (PMIC) family. It is a high voltage, low noise, fast security, on-board voltage regulator. The device contains an integrated current limiter and overvoltage protection. The MIC37501-1.5BR TR has a wide range of application fields, ranging from automotive to consumer and industrial applications. It is designed to be used in applications such as voltage regulation, Li-ion/ Li-Po battery charging/ protection, overvoltage protection, motor control, and many more.

The MIC37501-1.5BR TR is a voltage regulator with adjustable output voltage. The output voltage can be adjusted by varying the control voltage. The device is capable of operating at peak input voltages up to 25V and has a low quiescent current of 4.5mA. It has an adjustable rise time of 1.0 µs and adjustable fall time of 0.45 µs. It is capable of handling 1A of output current, and has a low output noise of 10 mVpp.

The device is equipped with several integrated features, such as: low ripple current, output current limitation, fast overvoltage protection, overcurrent protection, and reverse current protection. In addition, the device features a power-down mode, which allows the user to set the device into low-power mode, in which the regulator output current is limited to 0.3mA. This feature makes the device suitable for use in battery-operated systems and portable electronics.

The working principle of MIC37501-1.5BR TR is simple. The device consists of three main components, namely an adjustable voltage reference, a current-sense amplifier, and an output amplifier. The adjustable voltage reference is used to regulate the output voltage by comparing the input voltage and the reference voltage. The output voltage is controlled by an external control voltage. When an external voltage is applied, the voltage reference adjusts its output to match the external voltage, thus creating a variable output voltage.

The current-sense amplifier is used to detect the output current, and the output amplifier is used to control the current. The output amplifier and the current-sense amplifier work together to ensure that the output current remains at a constant value. The output voltage is then regulated directly by the voltage reference. The device has built-in thermal protection and a power-down mode to reduce power consumption and improve efficiency.

The MIC37501-1.5BR TR has a wide range of application fields, such as motor control, Li-ion/ Li-Po battery charging and protection, overvoltage protection, and various consumer and industrial applications. The device is equipped with a number of integrated features such as low output noise, fast turn-on time, low quiescent current, reverse current protection, and adjustable rise and fall times. This makes the device suitable for use in a variety of applications.
