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

is 1.0

Ω or less can 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.

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 “Typical Characteristics” for

details.
