* Size your output capacitor to meet the transient loading requirement. If you have a very dynamic load, a larger capacitor will improve
the response to these load steps (see charts 2&3)
(Unless otherwise specified, the following specifications apply over the operating ambient temperatures for the LX8630-xxC with 0°C ≤
≤ TA 125°C; VIN = VOUT + 1.5V; IOUT = 10mA; CIN = 10 ' (OUT ) ' *J = TA. Test conditions: Low duty cycle pulse testing
techniques are used which maintains junction and case temperatures equal to the ambient temperature.)
