Temperature range guaranteed by design, not production tested. 6. Smaller footprint associated to lower working voltages (10 V or 6.3 V, size 0805 or 0602) can be used, but care must be observed to prevent DC bias effect on the capacitance final value. See capacitor manufacturer data sheets. 7. Ceramic X7R, ESR < 100 m W, SMD type capacitors are mandatory to achieve the Iout specifications. Depending upon the PCB layout, it might be necessary to use two 2.2 mF/6.3 V/ceramic capacitors in parallel, yielding an improved Vout noise over the temperature range. On the other hand, care must be observed to take into account the DC bias impact on the capacitance value. See ceramic capacitor manufacturer data sheets. 8. Digital inputs undershoot < − 0.30 V to ground, Digital inputs overshoot < 0.30 V to Vbat. |
