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-1132 Series enables use of a low ESR
capacitor, such as a ceramic capacitor, for the output-side capacitor C
be used.
The accuracy of the output voltage is ensured at ±1.0% under the specified conditions of fixed input voltage
output current, and fixed temperature.
*1. Differs depending on the product.
Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output
voltage changes due to a change in the input voltage with the output current remaining unchanged.
