4. Output Current: Capable of delivering up to 1A, suitable for various low-power applications.
5. Thermal Protection: Includes built-in over-temperature protection to prevent damage due to overheating.
6. Current Limiting: Provides protection against overcurrent conditions.
7. Low Quiescent Current: Ensures minimal power consumption when the load is disconnected.
8. Packaging: Available in various packages, including SOT-223, TO-252, etc., for versatile mounting and use.
9. Stability: Requires external capacitors for stability but provides smooth and reliable performance.
10. Applications: Widely used in telecommunications, computers, and industrial systems for power regulation.
These features make the AMS1117CD-3.3 a reliable choice for ensuring a consistent power supply in electronic circuits.
Pinout
1. Vin (Input): This pin receives the input voltage, which should be higher than the desired output voltage by at least the dropout voltage to ensure proper regulation.
2. Vout (Output): This pin provides the regulated 3.3V output to the load.
3. GND (Ground): This pin serves as the ground reference for both input and output voltages.
The device is designed to supply up to 1A of output current with a typical dropout voltage of around 1.1V at maximum load. It is suitable for applications requiring a stable 3.3V power source, such as microcontrollers, sensors, and other low-power devices. Proper capacitor selection at the input and output is recommended to ensure stability and performance.
