Caution
The above connection diagram and constant will not guarantee successful operation.
Perform
thorough evaluation using the actual application to set the constant.
Application Conditions
Input capacitor (CIN) : 1.0 μF or more
Output capacitor (CL) : 1.0 μF or more
Equivalent series resistance (RESR) of output capacitor : 1.0 Ω or less
Caution A general series regulator may oscillate, depending on the external components selected. Check that
no oscillation occurs with the application using the above capacitor.
Selection of Input Capacitor (CIN) and Output Capacitor (CL)
The S-1167 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 1.0
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 1.0
μF or more and an equivalent series
resistance (RESR) of 1.0 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 1.0
μF or more for CIN and 1.0 μF or more for CL; however,
when selecting the output capacitor, perform sufficient evaluation, including evaluation of temperature
characteristics, on the actual device.
