Panasonic recommends a 4-layer PCB with a solid ground plane and a separate power plane for the input and output. The input and output capacitors should be placed as close as possible to the IC pins, and the PCB should be designed to minimize electromagnetic interference (EMI).
To ensure stability, Panasonic recommends using a minimum output capacitance of 10uF with an ESR of 1Ω or less. The output capacitor should be placed close to the IC and connected to a solid ground plane. Additionally, the input voltage should be stable and within the recommended range.
While the datasheet specifies an operating temperature range of -40°C to 85°C, Panasonic recommends an ambient temperature of 70°C or less for reliable long-term operation. Higher temperatures may affect the IC's reliability and lifespan.
The DZ2708200L is designed to withstand moderate vibration, but Panasonic recommends taking additional precautions for high-vibration environments. This may include using a more robust PCB design, securing the IC with a mechanical fastener, and ensuring the input and output capacitors are securely attached to the PCB.
To troubleshoot output voltage issues, Panasonic recommends checking the input voltage, output capacitance, and PCB layout. Ensure the input voltage is within the recommended range, the output capacitance meets the minimum requirements, and the PCB layout is designed to minimize EMI and noise. If issues persist, consult the application notes and contact Panasonic support for further assistance.
