The UZ1084L-3.3V is a low dropout (LDO) voltage regulator manufactured by UTC (Unisonic Technologies Co., Ltd.). This regulator is designed to provide a stable 3.3V output voltage from a higher input voltage with minimal voltage drop, making it suitable for battery-powered and other voltage-sensitive applications.

Applications:

• Microcontroller Power Supplies
• Post Regulation for Switching Power Supplies
• Battery-Powered Devices
• High-Efficiency Linear Regulators
• Motherboard Applications

Features:

• Fixed Output Voltage: 3.3V
• Low Dropout Voltage: Typically 1.3V at 5A
• Output Current: Up to 5A
• Thermal Overload Protection: Protects the regulator from overheating
• Current Limiting: Prevents damage from excessive output current

Benefits:

• Stable 3.3V Output: Provides a consistent voltage supply for sensitive components
• High Efficiency: Low dropout voltage minimizes power dissipation, improving efficiency, especially in battery-powered applications.
• Overload Protection: Thermal overload and current limiting protect the regulator from damage.
• Easy to Use: Requires minimal external components for operation.
• High Current Capability: Capable of supplying up to 5A of current.

Additional Details:

The UZ1084L-3.3V is available in TO-220, TO-263, and other surface-mount packages. The input voltage should be higher than the output voltage plus the dropout voltage. It is designed to operate within a wide temperature range. The low dropout voltage makes it particularly useful in applications where the input voltage is close to the desired output voltage, such as in battery-powered devices or post-regulation scenarios. The high current capability enables it to power a variety of digital and analog circuits requiring a stable 3.3V supply.
