Application Conditions
Selection of Input and Output Capacitors (C
Caution The above connection diagram and constant will not guarantee successful operation.
Caution A general series regulator may oscillate, depending on the external components selected.
The S-1170 Series requires an output capacitor between the VOUT and VSS pins for phase compensation.
A ceramic capacitor with a capacitance of 4.7 μF or more provides a stable operation in all temperature
ranges. When using an OS capacitor, tantalum capacitor, or aluminum electrolytic capacitor, a ceramic
capacitor with a capacitance of 4.7 μF or more and an ESR of 0.5 Ω or less is required.
The output overshoot and undershoot values, which are transient response characteristics, vary depending
on the output capacitor value. The required capacitance value for the input capacitor differs depending on
the application.
The recommended application values are, C
