Selection Output Capacitor (CL)
S-1111/1121 Series performs phase compensation using internal phase compensator (Equivalent Series Resistance) output capacitor enable stable operation independent changes output load. Therefore, always place capacitor (CL) more between VOUT pins. stable operation S-1111/1121 Series, essential employ capacitor whose within optimum range. Using capacitor whose outside optimum range (approximately whether larger smaller, cause unstable output, resulting oscillation. this reason, tantalum electrolytic capacitor recommended. When ceramic capacitor capacitor with used, necessary connect additional resistor that serves series with output capacitor. required resistance value approximately which varies depending usage conditions, perform sufficient evaluation selection. Ordinarily, around recommended. Note that aluminum electrolytic capacitor increase temperature, causing oscillation. When using this kind capacitor, perform thorough evaluation, including evaluation temperature characteristics.

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 increase when series regulator used load current (1.0 less). This performs phase compensation using internal phase compensator output capacitor. Therefore, always place capacitor more between VOUT pins. tantalum type capacitor recommended. Moreover, secure stable operation S-1111/1121 Series, necessary employ capacitor with within optimum range (0.5 Using capacitor whose outside optimum range (approximately whether larger smaller, cause unstable output, resulting oscillation. Perform sufficient evaluation under actual usage conditions selection, including evaluation temperature characteristics. voltage regulator oscillate when impedance power supply high input capacitor small input capacitor connected. application conditions input voltage, output voltage, load current should exceed package power dissipation. apply electrostatic discharge this that exceeds performance ratings built-in electrostatic protection circuit. determining output current, attention should paid output current value specified Table electrical characteristics footnote table. claims responsibility disputes arising connection with infringement products including this patents owned third party.
