Application Fields

XC6210B332MR-G is a versatile voltage regulator suitable for various applications. It is widely used in Audio amplifiers, Monitor controllers, Computer peripherals, Consumer products, Automotive electronics, Telecom systems, Security systems, Industrial electronics and other portable devices for power supply design.

Working Principle

The XC6210B332MR-G is a linear voltage regulator, commonly referred to as a "variable regulator". It operates by controlling the current flowing from its output pin to its adjustable pin (ADJ). The regulator compares the voltage on the Adjustable (ADJ) pin with a reference voltage and adjusts the output voltage accordingly. A voltage divider is typically used to adjust the output voltage. The design of the voltage divider depends on the required output voltage, input voltage, and allowed current dissipation of the resistors.

The regulator uses an error amplifier circuit to compare the outputs of the reference voltage and the voltage divider. The error amplifier then drives the pass transistor such that the output voltage (VOUT) is regulated. The current limiting and over temperature protection circuits are employed to protect the regulator from operating out of its rated conditions.

The XC6210B332MR-G includes a wide range of features such as fast transient response, low standby current, low output noise, neat layout and cost-effective components. This makes it suitable for high performance, reliable and low cost power supply designs.
