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.
