PMIC - Voltage Regulators - Linear

The S-L2980A43PN-TF-G voltage regulator is a linear regulator that utilizes a three-terminal configuration and is typically used to analyze an output voltage from an external circuit to stabilize or regulate the voltage in the circuit. This device is especially useful when dealing with digital circuits as the voltage is easier to measure and maintain. Its three-terminal configuration allows for easy management of the supply and output voltages.

Working Principle

The S-L2980A43PN-TF-G IC is a low-noise, high-precision voltage regulator device. This device is based on the principle of Feedback Regulation which utilizes the concept of closed-loop feedback. It is designed to be used in a linear regulator configuration, where the output is constantly being compared against a reference voltage. If the output is less than the reference voltage, the device adjusts the output by increasing its bias current. When the output is greater than the reference voltage, the device begins to reduce the bias current.

The device uses a series of components such as an error amplifier, a voltage reference, and a pass transistor to control the output voltage. The error amplifier amplifies the difference between the output voltage and the reference voltage, the voltage reference provides a reference voltage, and the pass transistor acts like a switch to allow or reject current through it. The device is capable of selecting the best combination of resistor values to deliver voltage regulation.
