PMIC is an abbreviation for power management integrated circuit. A voltage regulator is a type of PMIC designed to provide the correct amount of voltage from a power source to a device that requires power. It helps the device run at its optimal level, not too little or too much voltage. One example of a PMIC voltage regulator is the MIC39100-2.5BS TR. This article will discuss the application field and working principle of this PMIC.

Application Field

The MIC39100-2.5BS TR can be used in a variety of applications, including automotive, industrial, and consumer goods. It can also be used in renewable energy applications, like solar or wind energy applications, as well as medical applications. The device is ideal for these applications because it can operate over a wide temperature range (-40°C to 85°C) and operate with a wide input voltage range (4.5V to 16V). It is also capable of supplying up to 2.5A of continuous current.

Working Principle

The MIC39100-2.5BS TR is a linear voltage regulator, meaning it works by taking an input voltage and then stepping it down to the desired output voltage. This is done via a series of transistors and resistors, which together form an internal control loop. The transistors act as switches that are controlled by the control loop. The resistors provide the stability of the circuit, and the current output is set by the feedback signal.

The MIC39100-2.5BS TR has an internal reference voltage which is used to compare the output voltage against the reference voltage. When the voltage drops below the reference voltage, the transistors switch on and allow more current to flow, which increases the output voltage. When the output voltage exceeds the reference voltage, the transistors switch off and limit the current flow, which decreases the output voltage.

The MIC39100-2.5BS TR also features a low-dropout feature, which allows the regulator to continue regulating voltage even when the input voltage gets very close to the desired output voltage. This feature is useful in situations where a low output voltage is desired and the input voltage is very close. It also helps to ensure that the output voltage remains stable even when the input voltage is changing.

Conclusion

The MIC39100-2.5BS TR is a PMIC voltage regulator, specifically a linear voltage regulator, and can be used in a variety of automotive, industrial, consumer goods, and renewable energy applications. It has an internal reference voltage and low-dropout feature which helps to maintain a stable output voltage. The MIC39100-2.5BS TR can also operate over a wide temperature range and with a wide input voltage range.
