The KIA1117AS33RTK/P is a low dropout (LDO) linear regulator manufactured by KEC. It is designed to provide a stable and regulated 3.3V output voltage from a higher input voltage, with a low dropout voltage, meaning it can maintain regulation even when the input voltage is only slightly higher than the output voltage.

Applications

• Post Regulation for Switching Power Supplies
• Battery Chargers
• Microprocessor Power Supplies
• Motherboard applications
• Set-top boxes
• LCD Monitors

Features

• Low Dropout Voltage: Ensures stable output voltage even with low input voltage.
• 3.3V Fixed Output Voltage: Provides a precise and stable output voltage.
• Over Current Protection: Protects the regulator from damage due to excessive current draw.
• Thermal Shutdown Protection: Prevents the regulator from overheating and causing damage.
• SOT-223 Package: Allows for efficient heat dissipation.
• High Accuracy: Provides a precise output voltage, suitable for sensitive applications.
