It also provides a Step-Up selectable low-dropout operation with a tight positive output accuracy of ±1 percent over-temperature and line/load. The UA7824CKTTR is well suited for automotive, industrial, and telecom applications.

Application Fields

The UA7824CKTTR is widely applicable to many different types of automotive, industrial and telecom applications including:

• Automotive airbag systems
• Power distribution systems
• Industrial motor control systems
• Telecom base stations
• Telephone systems
• LED lighting systems

The diverse applicability of the UA7824CKTTR is due to its integrated high-side and low-side short circuit fault protection features, tight positive output accuracy, and low standby current drawn during normal operation. These features make the UA7824CKTTR an ideal power supply choice when performance, reliability and long system life are required.

Working Principle

The UA7824CKTTR is a linear voltage regulator from within the PMIC - Voltage Regulators - Linear product family. It operates by taking an input voltage such as 5V/12V and providing a regulated output voltage such as 3.3V, 5V and 12V. The device uses bi-directional current flow to regulate output voltage to the desired level. The device operates in both step-up and step-down mode, allowing it to be used in both applications. The device includes an integrated voltage reference that enables precise, stable output voltage regulation. Additionally, the device has an integrated 0.6V start-up voltage and low minimum operating voltage, allowing it to be used in a variety of automotive, industrial and telecom applications that require minimum voltage regulation.

The device also provides over-current protection and over-temperature protection. The device features short circuit protection and thermal shutdown features which prevent the device from becoming damaged in case of an output short or an over-temperature situation. Additionally, the device has an integrated reset function that helps to keep it in a safe operating state.

The integrated Active-Pull Down Clamp (APDC) feature of the UA7824CKTTR helps to protect the device from over-voltage conditions. The APDC feature reduces the transient response time of the linear regulator and improves its overall input-output regulation. Additionally, the APDC feature helps to improve efficiency and reduce power dissipation at high load. The output accuracy of the UA7824CKTTR is ±1% over-temperature and line/load.
