The TS1086 is a low dropout positive voltage regulator capable of providing up to 1.5A of output current. It's designed to deliver a stable and regulated voltage supply, even when the input voltage is close to the desired output voltage. This makes it an efficient solution for applications where voltage headroom is limited.

Applications

• Post Regulator for Switching Power Supply
• Battery Chargers
• Power Management for Computer Motherboard, Graphic Card
• LCD Monitor and LCD TV Power
• Set Top Box

Features

• Low Dropout Voltage: Typically 1.2V at 1.5A output current.
• Adjustable Output Voltage: Allows for customized voltage settings using external resistors.
• Fixed Output Voltage Options: Available in standard fixed voltage options like 3.3V, 5V, etc.
• Current Limiting: Protects the regulator and the load from overcurrent conditions.
• Thermal Shutdown: Shuts down the regulator when the junction temperature exceeds a safe limit, preventing damage.
• Reverse Battery Protection Prevents damage if the battery is connected with reversed polarity.

Benefits

• Improved Efficiency: Low dropout voltage minimizes power dissipation, resulting in higher efficiency.
• Stable Output Voltage: Provides a consistent and reliable voltage supply, ensuring proper operation of downstream components.
• Overload Protection: Current limiting and thermal shutdown features protect the regulator and the load from damage due to overcurrent or overheating.
• Flexibility: Adjustable output voltage option allows for customization to meet specific application requirements.
• Simplified Design: Requires minimal external components, simplifying the design process.
