Working Principle

A linear regulator, such as the MIC94310-GYCS-TR, operates on the principle of a voltage divider. A voltage divider is a circuit consisting of two resistors, connected in series. An input voltage is applied to the series and a fraction of the input voltage will appear across the resistors. The fraction of the input voltage that appears across each resistor is proportional to the resistance of each resistor. The voltage divider is used to regulate the output voltage, such that the output voltage will always equal the ratio of the two resistors, regardless of the input voltage.

The MIC94310-GYCS-TR utilizes a voltage divider to regulate the output voltage. The voltage divider consists of two resistors, a variable resistor and a fixed resistor. The variable resistor is controlled by a voltage feedback loop, which adjusts the resistance of the variable resistor based on the feedback voltage. If the output voltage is higher than the setpoint, the feedback loop will reduce the resistance of the variable resistor, reducing the output voltage. If the output voltage is lower than the setpoint, the feedback loop will increase the resistance of the variable resistor, increasing the output voltage.

Summary

The MIC94310-GYCS-TR, classified under PMIC - Voltage Regulators - Linear, is a three-terminal integrated linear regulator. It is a 1A low dropout (LDO) regulator which operates as a positive voltage regulator and provides good accuracy for precision regulation.
