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, and the thermal pad should be connected to a ground plane to reduce thermal resistance.
To ensure stable operation with a high-impedance output load, add a 10nF to 100nF capacitor in parallel with the output to reduce oscillation and improve stability. Additionally, consider adding a series resistor (e.g., 10Ω to 100Ω) to the output to dampen oscillations.
Although the datasheet doesn't specify a maximum voltage for the EN pin, it's recommended to keep it within the VCC range (i.e., 2.5V to 5.5V) to ensure proper operation and prevent damage to the device.
While the R6020JNXC7G is rated for operation up to 105°C, it's essential to consider the derating curves and thermal management to ensure reliable operation. ROHM recommends a maximum junction temperature of 125°C, and the device should be derated accordingly based on the ambient temperature.
To minimize EMI, use a shielded layout, keep the output traces short, and add a 10nF to 100nF capacitor between the output and GND. Additionally, consider using a common-mode choke or a ferrite bead on the output to reduce EMI radiation.
