Working principle

The MIC5213-3.0YM4-TR regulator works using a combination of MOS and linear technology. The MOS devices provide rapid transient response and excellent overall load regulation, while the low-noise linear section ensures low-output voltage noise. The MOS devices control the output voltage of the regulator, while the linear portion amplifies the small voltage drop between the MOS devices and the output voltage, to maintain the output voltage to within the specified accuracy. The load current is adjusted by the MOS devices, so that the output voltage remains stable. The MIC5213-3.0YM4-TR also has a circuit which reduces inrush current on start-up and also protects against overloads.

The MIC5213-3.0YM4-TR regulator is a highly efficient and reliable voltage regulator solution for automotive, consumer, healthcare and industrial applications. Its low-noise and low quiescent current make it an ideal power supply for automotive and consumer applications, while its high output voltage accuracy and excellent load transient response make it suitable for healthcare and industrial applications.
