Working Principle

The MAX8512ETA+T is a three-terminal linear voltage regulator that features an internal transistor, an error amplifier, and reference voltage source. The input voltage is supplied to the P-channel MOSFET which is connected to the OUT voltage to provide the regulated voltage output. The error amplifier compares the current reference voltage to the actual output voltage and adjusts the gate voltage to the MOSFET accordingly. As the output voltage changes, the MOSFET supplies more or less voltage to the output, thereby maintaining the desired output voltage. The MAX8512ETA+T also features current limiting and thermal shutdown to protect the device from excessive current draw and excessive heating.

Conclusion

The MAX8512ETA+T is a three-terminal low-dropout linear voltage regulator specifically designed for automotive, industrial, medical and other battery-powered systems. It features an adjustable output voltage range of 1.270V to 30V, low-dropout voltage of <30mV, low-noise operation of <9µV RMS and high current capability of 1.2A. Furthermore, the device is protected against excessive current draw and excessive heating via its current limiting and thermal shutdown circuitry.
