Instructions:
Mounting:
- Place the LC3664RL on the PCB with the correct orientation as indicated by the silkscreen.
- Ensure that the leads are soldered securely to the PCB pads.
Input Capacitor:
- Connect a 1μF ceramic capacitor between the input pin (VIN) and ground (GND) as close to the regulator as possible to ensure stability.
Output Capacitor:
- Connect a 1μF ceramic capacitor between the output pin (VOUT) and ground (GND) to maintain output stability.
Thermal Management:
- If operating at high output currents, ensure adequate heat dissipation by using a heatsink or a larger copper area on the PCB.
Power-On Sequence:
- Apply the input voltage (VIN) slowly to avoid inrush current issues.
- Monitor the output voltage (VOUT) to ensure it stabilizes at 3.3V.
Overcurrent and Thermal Protection:
- The LC3664RL includes overcurrent and thermal shutdown protection. In case of an overload, the device will automatically shut down to prevent damage.
Storage:
- Store the device in a dry, cool place within the specified storage temperature range to prevent damage.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal components. Use proper ESD protection measures.
