As technology and electronics grow ever more complex, special purpose voltage regulators are becoming increasingly important. The MAX17021GTL+T is a linear voltage regulator from Maxim Integrated Products, specifically designed for advanced power management applications. This application field and working principle will be discussed in this article.

Description

The MAX17021GTL+T is a linear voltage regulator designed to provide low-power, low-dropout performance in a variety of applications. It has an input voltage range of 2.7V to 5.5V, and can provide up to 500mA of output current with a dropout voltage as low as 0.5V. The device also features adjustable output voltage, polarity protection and protected shutdown. The MAX17021GTL+T is available in a small, RoHS-compliant, 5-pin SOT23 package, making it suitable for use in mobile, battery-powered applications.

Application Field

The MAX17021GTL+T is ideal for a variety of applications, including systems powered by rechargeable Lithium-ion batteries. It can also be used in automotive infotainment systems, personal navigation systems, and DC motor speed controls. The MAX17021GTL+T is designed to operate over a wide temperature range (-40°C to +125°C) and is available in a wide range of output voltages (1.2V to 5V). These features make it well-suited for use in industrial, medical, and consumer applications.

Working Principle

The MAX17021GTL+T is a linear voltage regulator that operates by constantly comparing the voltage at its output pin to a reference voltage, and then maintaining a voltage difference between them. This reference voltage, called the output voltage, is the voltage that the regulator supplies to the load. The internal circuits of the regulator will then adjust the current supplied to the load until the difference between the load voltage and the reference voltage is maintained. In this way, the regulator is able to maintain a constant output voltage, even as the input voltage, load current, and temperature change.

The MAX17021GTL+T has a wide input and output voltage range, making it suitable for a variety of applications. The device also features over-temperature protection and current limit protection, which provides additional protection against faults. Additionally, the device is designed to be low-noise and is able to provide high output current up to 500mA, making it well-suited for use in applications such as mobile phones, tablets, and other battery-powered devices.

Conclusion

The MAX17021GTL+T from Maxim Integrated Products is an advanced linear voltage regulator with an input voltage range of 2.7V to 5.5V and an output voltage range of 1.2V to 5V. It features adjustable output voltage, polarity protection, and protected shutdown, making it suitable for a wide range of applications including systems powered by rechargeable Lithium ion batteries and mobile, battery-powered applications. The MAX17021GTL+T is an excellent choice for advanced power management applications.
