1. Basic Operation – continued
(3) Soft Start
When the EN Voltage (VEN) goes high, the soft start function operates and the output voltage gradually rises. This soft
start function can prevent overshoot of the output voltage and excessive inrush current. The soft start time tSS can be
set by connecting a capacitor to the SS/REF pin. For the setting method, refer to Selection of Components Externally
Connected 4. Soft Start Capacitor.
