„ Selection of Input and Output Capacitors (CIN, CL)
The S-1132 Series requires an output capacitor between the VOUT and VSS pins 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, a ceramic capacitor with a capacitance
of 0.1 µF or more and an ESR of 2.0 Ω or 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 CIN and 0.1 µF or more for CL; however, when selecting the
output capacitor, perform sufficient evaluation, including evaluation of temperature characteristics, on the actual device.
