Soft start function When ON/OFF-pin(2pin) is connected to Vin,soft start function operates. And output voltage rises gently, applying restriction to current. And a product is protected from overshoot output voltage or inrush current. Soft start time is as section6.1. 7.5. Power Good(Output voltage detection function) A Power Good-pin(6pin) is the open drain output. When the output voltage becomes -10%(typ.) for a set voltage, High is output. When the output voltage becomes -13%(typ.) for a set voltage, Low is output. 7.6. Input External capacitor It is recommended to connect a ceramic capacitor or a low-impedance electrolytic capacitor of 47μF or more at Vin terminal. Smaller input capacitor may leads to an unstable operation of this product caused by input voltage fluctuation. Please check the proper operation of it on your product when smaller input capacitor is used. Using ceramic capacitors as input capacitor may cause an increase of output voltage, because input ripple current flows through the external input capacitor and wiring resistance. This phenomenon is affected by the position of external capacitors, the value of external capacitors and voltage difference between Vin and Vout. Using low-impedance electrolytic capacitor will ease this problem. Please check the proper operation of it on your product when ceramic input capacitor is used.
