The S-1206 Series requires an output capacitor between the VOUT pin and VSS pin for phase compensation.
Operation is stabilized by a ceramic capacitor with an output capacitance of 0.1 µF or more in the entire temperature
range. However, when using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor with a capacitance
of 0.1 µF or more less is required.
The value of the output overshoot or undershoot transient response varies depending on the value of the output
capacitor.
The required capacitance of the input capacitor differs depending on the application.
The recommended value for an application is 0.1 µF or more for C
these capacitors, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.
