MIC37100-1.65BS TR Application Field and Working Principle

The MIC37100-1.65BS TR is one of the most popular voltage regulators in the PMIC - Voltage Regulators - Linear series. This regulator offers high accuracy and low power operation, and is designed to meet a wide range of requirements for today\'s digital or analog applications. It features an adjustable and selectable output from 1.8V to 4.5V using a resistive divider connected to the output.

This regulator is particularly suitable for a wide range of applications requiring an output voltage that is constant and adjustable with excellent current and noise suppression. It is also well suited for battery powered applications, as its low power consumption allows the use of lower power supplies. It can be used in a wide range of audio, video, industrial, medical, and other medium-to-low current applications.

Working Principle

The MIC37100-1.65BS TR employs a three-terminal voltage regulator with a high-impedance Shunt Regulator. It works by regulating the input voltage source and maintaining a constant steady state output voltage. Three terminals are used to provide power, sense inputs, and enable/disable the linear voltage regulator. The enable/disable function provides an easy way to enable/disable the voltage regulator. The enable/disable pin is used to enable or disable the regulator by providing the required logic level at the enable/disable pin.

The MIC37100-1.65BS TR is equipped with an integrated, digitally programmable, internal reference generator. This internal generator eliminates the need for an external reference voltage and allows for a wide range of adjustment from 1.8V to 4.5V. The reference generator is connected to the output through a series resistor divider network to allow for the desired output voltage. The reference generator also generates a voltage that is proportional to the output voltage and is used to monitor the output voltage using the sense terminals. A comparison amplifier is used to ensure that the output voltage is within the desired range. In the event that the output voltage drops too low, the amplifier automatically compensates by increasing the drive current to the output and thus restoring the output voltage to the desired level.

The MIC37100-1.65BS TR is a versatile voltage regulator with an adjustable output, allowing the user to customize the output voltage. Its low power consumption makes it ideal for battery powered applications, while its high accuracy, noise suppression, and wide range of adjustment make it suitable for a variety of medium-to-low current applications.
