4. Protection: Includes built-in protection features such as current limiting and thermal shutdown, which protect the IC from damage due to overcurrent and overheating.
5. Package Options: Available in various package options, including SOT-223, TO-252, and SOIC-8, for flexibility in different applications.
6. Line Regulation: Excellent line regulation (typically 0.2%/V) ensures stable output despite variations in input voltage.
7. Application: Suitable for use in a variety of applications, including power supplies for microcontrollers, battery-powered devices, and other low-voltage systems.
These features make the AMS1117-1.2 a versatile and reliable component for voltage regulation needs.
Pinout
1. VIN (Input Voltage): This pin is where the input voltage is supplied. It typically requires an input voltage higher than the desired output voltage by at least the dropout voltage.
2. GND (Ground): This pin is the ground connection and serves as the reference point for the input and output voltages.
3. VOUT (Output Voltage): This pin provides the regulated output voltage of 1.2V.
The AMS1117-1.2 is designed to provide a stable output with a dropout voltage of approximately 1.1V at full load, making it suitable for applications requiring a 1.2V power supply from a higher voltage source. It is typically used in post-regulation and voltage step-down applications.
