Introduction

MIC5313-F3YMT-TR is an integrated circuit from Microchip Technology. It is a three-terminal adjustable voltage regulator which offer a wide range of voltage options and is suitable for a variety of commercial and industrial applications. The MIC5313-F3YMT-TR is designed to provide constant voltage and current control with low dropout voltage, low quiescent current and fast transient response. It can be used to regulate voltages over the range of 1.2V to 40V, and delivers up to 150mA of output current.

Product Features

The MIC5313-F3YMT-TR is powered through a single input-supply voltage, with a wide input voltage range of 4.5V to 40V. It features an adjustable output voltage, with a range of ~1.2V to ~40V. The output voltage can be easily set using just two external resistors. The MIC5313-F3YMT-TR also has over current protection and thermal protection which can help improve system reliability and provide protection against unexpected power surges or device failures.The device also features high power supply rejection ratio (PSRR), low dropout voltage, and low quiescent current. The high PSRR allows for improved voltage regulation, even when the input voltage varies. The quiescent current is typically less than 200µA, which allows it to be used in applications with high power efficiency.The MIC5313-F3YMT-TR is also available in an adjustable version (MIC5313A-F3YMT-TR), which offers more flexibility with regards to setting the output voltage. The adjustable version requires two resistors to set the voltage.

Application Field

The MIC5313-F3YMT-TR is suitable for a variety of applications, including power management in computers and other electronic devices, and as a voltage supply for integrated circuits. It is also used in distributed power systems such as solar cell and fuel cell systems, server racks, and high-speed analog signals.The MIC5313-F3YMT-TR can be used to regulate voltage in applications that require a low quiescent current and high output accuracy, such as powering digital signal processors and integrated circuits. It is also used in applications which require tight voltage regulation, such as LED lighting systems and LCD backlighting.

Working Principle

The MIC5313-F3YMT-TR works by using a feedback loop, which is comprised of an output voltage setting resistor, a voltage reference and an error amplifier. When power is applied to the device, the error amplifier compares the output voltage to the reference voltage, and sends a signal to the output if the two voltages are not equal.The output voltage can be controlled by adjusting the value of the output voltage setting resistors. When the resistor is connected in series with the output of the device, the voltage drop across the resistor is added to the reference voltage. This adjusts the output voltage of the device.

Conclusion

The MIC5313-F3YMT-TR is a three-terminal adjustable voltage regulator designed for a wide range of applications. It offers high PSRR, low quiescent current and low dropout voltage. It is ideal for applications that require tight voltage regulation, such as LED lighting systems and LCD backlighting. The output voltage can be easily set using just two external resistors, and it features a variety of power protection features for improved reliability.
