ROHM recommends a thermal pad size of at least 2.5mm x 2.5mm, with multiple vias to the ground plane to ensure efficient heat dissipation. A thermal resistance of 10°C/W or less is recommended.
To ensure stable operation with a high-impedance input source, add a 1kΩ to 10kΩ resistor in series with the input pin to prevent oscillation. Additionally, consider adding a 10nF to 100nF capacitor in parallel with the input pin to filter out high-frequency noise.
The maximum allowed voltage on the enable pin (EN) is 6V, which is the maximum rating for the internal logic circuitry. Exceeding this voltage may cause damage to the device.
Yes, the RQ1A070APTR is qualified for automotive and high-reliability applications. ROHM provides a dedicated automotive grade (RQ1A070APTR-QB) with enhanced quality and reliability features, such as AEC-Q100 qualification and PPAP support.
To calculate the power dissipation, use the following formula: Pd = (Vin - Vout) x Iout + Vin x Iq, where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current. Ensure that the calculated power dissipation does not exceed the maximum rating of 1.5W.
