HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1142 Series
Explanation of Terms
1. Low dropout voltage regulator
2. Output voltage (V
3. Line regulation
4. Load regulation (ΔV
5. Dropout voltage (V
A voltage regulator which has a low dropout voltage due to its built-in low on-resistance transistor.
The accuracy of the output voltage is ensured at ±3.0% under 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
Indicates the dependency of the output voltage against the input voltage. That is, the value shows how much the
output voltage changes due to a change in the input voltage after fixing output current constant.
