A thermal pad is recommended under the package to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are suggested. Refer to ROHM's application note for detailed layout guidelines.
To ensure stable output voltage regulation, it's essential to decouple the input and output with ceramic capacitors (e.g., 10uF and 22uF, respectively). Additionally, a minimum output capacitance of 10uF is recommended to maintain stability.
The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this limit may affect the regulator's performance and stability.
The EDZVT2R3.9B is rated for operation up to 125°C. However, derating is required for temperatures above 85°C. Consult the datasheet for derating curves and thermal management guidelines.
To protect the regulator from input voltage surges, consider adding a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input. This will help prevent damage from voltage spikes and transients.
