Line
The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in
low on-resistance transistor.
A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1170 Series enables use of a low
ESR capacitor, such as a ceramic capacitor, for the output-side capacitor C
0.5 Ω or less can be used.
The accuracy of the output voltage is ensured at ±1.0% under the specified conditions of fixed input
