PMIC - Voltage Regulators - Linear

Voltage regulators are essential safety and reliability components in power systems. They provide consistent voltage to the connected load or system, despite any changes in load or delivered power. This means that the regulator must be able to adjust power and serve as a link between the power source and system circuitry. Linear voltage regulators are by far the most common type of voltage regulator device, and are used for cost efficiency in a wide range of applications, from embedded systems to large automotive or industrial applications. This article will discuss the application field and working principle of the ZSR500GTC voltage regulator.

Application Field

The ZSR500GTC voltage regulator is a type of three-terminal linear regulator that is designed to provide regulated output voltage between 1.2 and 5.0V. The device is well suited for a variety of applications, including telecom equipment, video game consoles, general-purpose systems, industrial equipment, and automotive electronics. Additionally, the device features over-current and thermal protection, as well as an on/off enable function. The device is available in a TO-220 package, making it ideal for use in high power applications.

Working Principle

The ZSR500GTC voltage regulator employs a linear control loop to regulate the output voltage. The output voltage is determined by a voltage reference source, usually a bandgap reference. The output current is proportional to the output voltage and is compared to a reference current from an internal current source. An error signal is regenerated through an internal amplifying process, and the output voltage is consequently adjusted to the desired voltage. By controlling the error signal and providing a constant voltage output to the system or load, the device is able to maintain an accurate and stable output voltage despite changes in the supply voltage or load current.

The ZSR500GTC is a popular choice of three-terminal linear regulator, due to its reliability and low cost. It is also very easy to use, making it popular in a wide range of applications. The ZSR500GTC also offers many other features such as over-current protection, as well as thermal and on/off enable functions, which makes it one of the best linear voltage regulators currently available.
