MC33375D-3.0G is a voltage regulator IC from the PMIC (Power Management IC) family, and one of the linear voltage regulators produced by Motorola. MC33375D-3.0G is capable of regulating voltages from 0.5V to 24V with currents up to 3.0A.

Application field

The MC33375D-3.0G can be applied to various tasks, such as providing a stable voltage to electronic circuits. It can be used as a voltage regulator in applications such as batteries, AC/DC adapters, DC/DC converters, and other circuits requiring a regulated voltage.

The MC33375D-3.0G can also be used in circuits requiring constant current such as LED drivers, current sources and current sinks. In addition, its current-limiting feature can be used in circuits requiring safety features such as over-voltage and over-current protection.

Working principle

MC33375D-3.0G operates on the same basic principle of linear voltage regulators, where a difference in voltage is measured between an input and output pin, and a controlled amount of current is maintained through an active element, typically a transistor such as a PNP or NPN type. In order to achieve regulation, the voltage difference must be adjusted by a feedback circuit.

The MC33375D-3.0G is designed to be configured in the following three ways: an adjustable output (where the end user can set the output voltage to the desired level using an external reference voltage), a linear feed-back configuration (where the output voltage is dependent on the feedback voltage of a voltage divider network), and a fixed output (where the output voltage is fixed at a predetermined voltage level).

The MC33375D-3.0G provides 3.0A of output current and is capable of regulating voltages from 0.5V to 24V. The IC also features short circuit protection and thermal shutdown. In addition, it has wide input voltage range and low noise operation.

Conclusion

MC33375D-3.0G is a versatile voltage regulator IC from the PMIC (Power Management IC) family. It is designed to regulate voltages from 0.5V to 24V with currents up to 3.0A. The IC is capable of being configured in the adjustable output, linear feedback, and fixed output modes, and provides numerous features such as short circuit protection and thermal shutdown. Therefore, MC33375D-3.0G is suitable for applications such as batteries, AC/DC adapters, DC/DC converters, LED drivers, current sources and current sinks.
