The maximum operating temperature range for the LM7321QMFE/NOPB is -40°C to 125°C.
Yes, the LM7321QMFE/NOPB is qualified for automotive and industrial applications, making it suitable for high-reliability uses.
To ensure proper biasing, connect the input voltage (VIN) to a stable voltage source, and decouple the input with a 1-μF capacitor to ground. Also, ensure the output voltage (VOUT) is properly decoupled with a 10-μF capacitor to ground.
To minimize noise and EMI, use a multi-layer PCB with a solid ground plane, keep the input and output traces short and separate, and use a shielded inductor. Also, place the input and output capacitors close to the device.
Yes, you can use multiple LM7321QMFE/NOPB devices in parallel to increase the output current. However, ensure that each device has its own input and output capacitors, and that the devices are properly synchronized to prevent oscillations.
