• Use this model according to a usual three terminal regulator.
• Output Voltage
• C1 : More than 100µF (In order to reduce the line impedance)
• C2 : Output capacitor built-in.
• Refer to figure 6~8 about :
• Refer to page 6 about :
In case that the wiring is long to the load, output noise may be
further reduced with the 2.2µF~4.7µF added.
