Instructions for LM1117IMP-3.3

  1. Mounting and Layout:

    • Ensure proper heat sinking if operating at high output currents.
    • Place input and output capacitors close to the device.
  2. Input Capacitor:

    • A 1 μF tantalum capacitor is recommended for stability.
    • For better transient response, a ceramic capacitor (e.g., 0.33 μF) can be added in parallel.
  3. Output Capacitor:

    • A 10 μF tantalum capacitor is suggested for optimal performance.
    • Larger values improve load regulation but may increase startup time.
  4. Application Notes:

    • The LM1117IMP-3.3 is designed for low dropout operation, making it suitable for battery-powered applications.
    • Ensure that the input voltage exceeds the output voltage by at least the dropout voltage to maintain regulation.
  5. Handling Precautions:

    • This device is sensitive to electrostatic discharge (ESD); handle with care.
    • Avoid exceeding maximum ratings to prevent damage or reduced lifespan.
  6. Storage:

    • Store in original packaging until ready for use to protect against ESD and physical damage.
