The UZ1085L-1.8V is a low dropout linear regulator manufactured by UTC (Unisonic Technologies Co., Ltd.). It's designed to provide a stable and regulated 1.8V output voltage with a low dropout voltage, making it suitable for applications where the input voltage is only slightly higher than the desired output. The UZ1085 series generally offers a higher current output than the UZ1084 series.

Applications:

• Powering low-voltage microcontrollers and processors.
• Memory power supplies (e.g., for DDR memory).
• Post-regulation of switching power supplies.
• Portable devices requiring a 1.8V rail.
• ASIC power supplies.

Features:

• Low Dropout Voltage: Allows for efficient regulation even with a small input-output voltage differential.
• 1.8V Fixed Output Voltage: Provides a precise and stable 1.8V output.
• High Output Current Capability: Supports a higher current draw than some competing regulators in its class.
• Over-Temperature Protection: Protects the device from thermal damage.
• Current Limiting: Prevents overcurrent conditions.

Benefits:

• Stable and Reliable 1.8V Supply: Ensures reliable operation of connected components.
• Efficient Power Conversion: Minimizes power loss due to its low dropout characteristics.
• Protection Features: Enhanced reliability and prevents damage from overloads or excessive temperature.
• Simplified Design: Requires minimal external components.

The UZ1085L-1.8V is often used in applications that require a stable 1.8V power supply with good current capabilities. It is typically available in surface mount packages like TO-252 or TO-263. Key specifications include a dropout voltage typically around 1.3V at maximum rated current, current limiting around 3A, and thermal shutdown protection. It is RoHS compliant and lead-free.
