Application Field

The MIC29300-12BU is highly suitable for a variety of applications, including automotive, industrial, computing, and consumer electronic systems. In particular, it is widely used in applications such as power management, battery charging systems, power supplies, DC-DC converters and microprocessor control systems. It can also be used in audio applications, such as high-end amplifiers, as well as in medical systems.

Working Principle

The MIC29300-12BU voltage regulator is designed to maintain a steady 5V output voltage across a wide range of input voltages from 5V to 20V. It operates in a linear regulation mode, meaning it works by regulating the input and output currents to match, rather than by relying on PWM or switching. Consequently, the output voltage remains stable regardless of load current, allowing for improved accuracy and precision over traditional switching regulators.

The MIC29300-12BU includes an integrated voltage feedback control circuit and an adjustable current limit. The feedback control circuit monitors the output voltage and adjusts the gate voltage of the pass transistor to maintain the regulated output. Furthermore, the MIC29300-12BU features an adjustable current limit that is programmed to a fixed value, allowing it to safely limit the maximum current and provide protection against over-current conditions.

Conclusion

The MIC29300-12BU voltage regulator is a high-performance, reliable and simple linear voltage regulator designed for use in a variety of applications. It offers a steady 5V output that is accurately trimmed for precision, low output ripple and fast transient response, as well as a high power supply rejection ratio. Furthermore, it is thermally protected and includes an adjustable current limit, allowing it to safely limit the maximum current and protect against over-current conditions.
