Linear voltage regulators are one of the most important types of power management integrated circuits (PMICs) used in many electronic systems today. The UC282T-ADJ is a linear voltage regulator that provides a stable regulated voltage to ensure proper operation of electronic components. In this article, we will discuss the application field and working principle of the UC282T-ADJ linear voltage regulator.

The UC282T-ADJ is a three-terminal adjustable linear voltage regulator that can output a voltage between 0.8V and 8V. This flexibility makes it suitable for use in many different applications. It is commonly used in automotive, industrial, and consumer electronics applications, such as power supplies, battery charging circuits, and motor control systems. It is also well-suited for use in portable devices like cell phones and portable media players, where it is used for charge management and low-power voltage regulation.

The UC282T-ADJ is based on a classic linear regulator architecture and utilizes an internal PMOS transistor, PNP series pass transistor, and 4.7kΩ resistor. It has a wide operational temperature range of -40C to +85C, low quiescent current, and high-efficiency operation. It is also designed to minimize noise and inrush current.

The UC282T-ADJ features an internal reference voltage of 1.25V, which is used to control the output voltage. The output voltage is adjustable through an external resistor divider network and can be set to any value between 0.8V and 8V. The device also has an enable pin for easy shutdown and is protected by current and thermal limiting. This makes it an ideal choice for portable devices that require precise voltage regulation.

The UC282T-ADJ features built-in soft start to reduce inrush current, as well as thermal shutdown protection to prevent damage to the device in the event of an over temperature condition. This makes it particularly well-suited for automotive applications, where precise voltage regulation is a must.

The UC282T-ADJ is an ideal choice for many power management applications. It is simple to use, easy to configure, and provides precise voltage regulation. Its wide temperature range, low quiescent current, and high-efficiency operation make it a great choice for automotive, industrial, and consumer electronics applications.
