Standard Circuit
The low dropout voltage regulator is a voltage regulator having a low dropout voltage characteristic due to
the internal low on-resistance transistor.
The accuracy of the output voltage is ensured at ±2.0 % under the specified conditions of input voltage,
output current, and temperature, which differ product by product.
Caution When the above conditions are changed, the output voltage may vary and go out of the
Line regulation indicates the input voltage dependence of the output voltage. The value shows how much
the output voltage changes due to the change of the input voltage when the output current is kept
constant.
