In the case of using a resistance "R" between VIN and control. The current flow into the control terminal while the IC is ON state (ICONT) can be reduced when a pull up resistance "R" is inserted between VIN and the control terminal. The minimum control voltage for ON state (VCONT (ON)) is increased due to the voltage drop caused by ICONT and the resistance "R". The ICONT is temperature dependence as shown in the "Control Current vs. Temperature" characteristics. Therefore, the resistance "R" should be carefully selected to ensure the control voltage exceeds the VCONT (ON) over the required temperature range. -4- Ver.2010-07-12 NJM2817 Input Capacitance CIN Input Capacitance CIN is required to prevent oscillation and reduce power supply ripple for applications with high power supply impedance or a long power supply line. Use the CIN value of 4.7F greater to avoid the problem. CIN should connect between GND and VIN as short as possible. Output Capacitance CO Output capacitor (Co) is required for a phase compensation of the internal error amplifier. The capacitance and the equivalent series resistance (ESR) influence stability of the regulator. If use a smaller Co, it may cause excess output noise or oscillation of the regulator due to lack of the phase compensation. Therefore, use Co with the recommended capacitance or greater value and connect between Vo terminal and GND terminal with minimal wiring. The recommended capacitance depends on the output voltage. Low voltage regulator requires greater value of the Co. Thus, check the recommended capacitance for each output voltage. Use of a greater Co reduces output noise and ripple output, and also improves transient response of the output voltage against rapid load change. This product is designed to work with any capacitor including a low ESR capacitor for the Co; however, refer "Equivalent Series Resistance vs. Output Current" and choose suitable capacitor. When distance from an IC to load is long, an IC may cause malfunction by wiring capacity and an L ingredient Please use it after having evaluated it enough.
