HIGH OPERATING VOLTAGE CMOS VOLTAGE REGULATOR S-812C Series Precautions
Wiring patterns VIN, VOUT pins should designed that impedance low. When mounting output capacitor between VOUT pins (CL) capacitor stabilizing input between pins (CIN), distance from capacitors these pins should short possible. Note that output voltage increased load current less than load current less than output voltage increase when regulating operation halted ON/OFF pin. prevent oscillation, recommended external parts under following conditions. Equivalent Series Resistance (ESR): less case using output capacitor) Input series resistance (RIN): less voltage regulator oscillate when power source impedance high input capacitor connected. attention operating conditions input/output voltage load current that power loss does exceed power dissipation package. apply electrostatic discharge this that exceeds performance ratings built-in electrostatic protection circuit. claims responsibility disputes arising connection with infringement products including this upon patents owned third party.
