ROHM recommends a thermal pad on the bottom of the package connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
To ensure stable operation, ROHM recommends using a bypass capacitor (e.g., 10uF) between the VIN pin and GND, and a decoupling capacitor (e.g., 100nF) between the VOUT pin and GND.
ROHM recommends keeping the input voltage ripple below 100mV to ensure stable operation and prevent oscillations.
While the LMR824F-GE2 can handle up to 500mA of output current, ROHM recommends derating the output current based on the ambient temperature and PCB thermal design to prevent overheating.
ROHM recommends using an external current limiting resistor or a fuse in series with the input voltage to protect the regulator from overcurrent and short-circuit conditions.
