Features
1. Output Voltage: Fixed at 3.3V.
2. Dropout Voltage: Low dropout voltage of approximately 1.2V, allowing efficient operation with a small difference between input and output voltages.
3. Output Current: Capable of delivering up to 800mA of output current.
4. Regulation: Offers good line and load regulation.
5. Thermal Protection: Includes thermal shutdown to protect against overheating.
6. Current Limiting: Built-in current limiting for added safety.
7. Package: Available in a compact SOT-223 package, suitable for space-constrained applications.
8. Stability: Requires only a small output capacitor for stability.
9. Applications: Ideal for use in various applications like post-regulation for switching supplies, battery chargers, and portable devices.
These features make the LM1117IMPX-3.3 a reliable choice for applications requiring a steady 3.3V output with moderate current demands.
Pinout
1. Pin 1 (GND/ADJ): This pin is the ground for the fixed versions and can also serve as an adjustment pin in adjustable versions of the LM1117 series (not applicable for the fixed 3.3V version).
2. Pin 2 (Output): This pin provides the regulated 3.3V output. It's where you connect the load that requires the regulated voltage.
3. Pin 3 (Input): This pin is for the input voltage, which must be higher than 3.3V plus the dropout voltage to ensure proper regulation.
The LM1117IMPX-3.3 typically requires only a small input and output capacitor for stability and operates with a low dropout voltage, making it suitable for applications where space and power efficiency are crucial.
