For value given, capacitor must be solid tantalum. If alumininum electrolitics are used, at least ten times value shown should be selected. CI is required if regulator is located an appreciable distance from power supply filter. (2) This diode is used to protect the regulator from output polarity reversals before input voltage is supplied. (3) To improve transient response. If large output capacitors are used, a high current diode from input to output Fig.2 VNO Test Circuit Fig.3 Ripple Rejection Test Circuit 2012. 11. 19 Revision No : 0 4/5 KIA7912PI 2012. 11. 19 Revision No : 0 5/5
