Technical Terms

1. Low Dropout Voltage Regulator

The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low-on-

resistance transistor.

2. Low Equivalent Series Resistance

The accuracy of the output voltage is ensured at

±1.0% or ±15 mV

voltage

Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range

of the output voltage. Refer to the “

Electrical Characteristics” and “

Characteristics (Typical

Data)” for details.
