It provides excellent AC performance, low dropout voltage and features current-limiting, short-circuit protection and short-load protection. With its low dropout voltage, it is a great solution for low-dropout regulator designs. Its low ground current allows for superior noise immunity and low power consumption.

Working Principle of the MIC5265-2.5YD5

The MIC5265-2.5YD5 is a Linear Voltage Regulator (LVR). LVRs are designed to provide a constant voltage output from an input voltage that is within a certain range. An LVR is made up of a pass transistor, usually a Field Effect Transistor (FET), that regulates voltage to the output based on a reference voltage, which is regulated by an adjustable reference diode. When the pass transistor is operating, current will flow through the reference diode and will generate a voltage drop that will determine the output voltage.

Accurate voltage regulation is achieved by monitoring the output voltage and applying it to the reference diode. This process is known as feedback loop. When the output voltage reaches the specified voltage level, the feedback loop will be interrupted, and the voltage of the reference diode will remain fixed. This will allow the pass transistor to adjust the output voltage and maintain a constant voltage level at the output terminals of the device.

The MIC5265-2.5YD5 is designed to operate with a maximum output current of 250 mA. It also has an adjustable output voltage ranging from 1 V to 16 V. It is designed with a temperature range of -40°C to 85°C, making it suitable for automotive and industrial applications. Additionally, it also has a low quiescent current of 84 μA, enabling it to provide superior power efficiency and high accuracy.

Conclusion

The MIC5265-2.5YD5 is an excellent choice for automotive, portable, and power-sensitive applications that require high-accuracy and low power consumption. Due to its low dropout voltage and low ground current features, as well as enhanced current limiting, short-loaded protection and superior AC performance, it is well-suited for noise-kills, power supplies, and low-dropout operation in switching regulators. Its adjustable output voltage and low quiescent current enable it to provide superior power efficiency and high accuracy, making it an ideal choice for a wide range of applications.
