The MIC2214-KNYML-EV is a highly efficient, low-voltage linear voltage regulator for a range of applications. This regulator integrates a set of features that provide excellent power supply reliability and cost efficiency. It is designed to be used with both single- and dual-voltage power supplies and is suitable for a variety of DC-to-DC converters, including DC/DC converters, DC/AC converters, LED drivers, and uninterruptible power supplies.

Application

The MIC2214-KNYML-EV is primarily designed for use in custom DC-to-DC converters, where it offers output voltage accuracy of ±0.5%, good transient response characteristics, and a wide input voltage range of 4.75 V to 42 V. It also features an adjustable output voltage range from 0.9 V to 5.5 V with a minimum output current of 15 mA. The wide output voltage range of the regulator allows it to be used for a broad range of DC-to-DC applications.

The MIC2214-KNYML-EV also has many useful features. It is UL recognized and offers low ripple and noise, excellent temperature stability, over-temperature, over-load and over-voltage protection, as well as over-current protection. It also has a soft start button for boosting system perfomance and a shutdown input pin for power savings when not in use.

Working Principle

The MIC2214-KNYML-EV linear voltage regulator works on the principle of conduction loss in an N-channel metal-oxide-semiconductor process. It integrates a N-channel MOSFET that is used to control the output voltage. When a voltage is applied to the control terminal of the MOSFET, the output voltage tracks the control voltage and is regulated. This regulator also features a current foldback mode which reduces the output voltage when the load current reaches the current foldback set point. This feature helps avoid overheating and thus, increases the reliability of the regulator.

The MIC2214-KNYML-EV is suitable for a range of DC-to-DC applications, from low-power motors, to commercial landscaping and small safety systems, to large power supplies for industrial and military needs. It offers robust performance and superior reliability. The adjustable output voltage range makes it an ideal choice for applications requiring accurate and reliable voltage regulation.
