Instructions for LM1117IMP-3.3
Mounting and Layout:
- Ensure proper heat sinking if operating at high output currents.
- Place input and output capacitors close to the device.
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.
Output Capacitor:
- A 10 μF tantalum capacitor is suggested for optimal performance.
- Larger values improve load regulation but may increase startup time.
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.
Handling Precautions:
- This device is sensitive to electrostatic discharge (ESD); handle with care.
- Avoid exceeding maximum ratings to prevent damage or reduced lifespan.
Storage:
- Store in original packaging until ready for use to protect against ESD and physical damage.
