

Explanation of Terms

1. Low dropout voltage regulator

This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.

2. Low ESR

A capacitor whose ESR (Equivalent Series Resistance) is low. The S-T111 Series enables use of a low

is 10

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

*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 “ Electrical Characteristics” and “

Characteristics (Typical Data)” for details.

much the output voltage changes due to a change in the input voltage with the output current remaining

unchanged.
