The UZ1084L-ADJ is an adjustable output, low dropout linear regulator manufactured by UTC (Unisonic Technologies Co., Ltd.). Unlike fixed-voltage regulators, the UZ1084L-ADJ allows the user to set the output voltage to a desired level within a specific range using external resistors. This flexibility makes it suitable for a wide variety of applications where different voltage levels are required.

Applications:

• Adjustable power supplies for prototyping.
• Post regulators for switching power supplies requiring custom voltages.
• Powering variable-voltage devices.
• Battery chargers with adjustable charging voltage.
• Voltage regulation in industrial control systems where specific voltage levels are needed.

Features:

• Adjustable Output Voltage: Output voltage can be set using external resistors.
• Low Dropout Voltage: Ensures stable regulation even with a small difference between input and output voltage.
• High Output Current Capability: Can supply ample current to power demanding loads.
• Over-Temperature Protection: Protects the regulator from thermal damage in high-load or high-temperature conditions.
• Current Limiting: Prevents excessive current draw, protecting both the regulator and the load.

Benefits:

• Flexibility in Output Voltage: Allows for easy adjustment of the output voltage to meet specific application requirements.
• Stable and Reliable Power: Provides a consistent output voltage at the set level, ensuring stable operation of connected devices.
• Efficient Power Conversion: Low dropout voltage minimizes power loss, improving overall system efficiency.
• Protection Against Overload: Built-in protection features enhance the robustness and reliability of the system.
• Simplified Design Customization: Adjusting the output voltage requires only the selection of appropriate external resistors.

The UZ1084L-ADJ typically uses an external resistor divider to set the output voltage. A typical dropout voltage specification is 1.3V at max current. Specifications also include current limiting around 1.5A and thermal shutdown protection, usually around 150°C. It is commonly available in surface mount packages such as TO-252 and TO-263, and is RoHS compliant and lead-free.
