HIGH RIPPLE-REJECTION LOW DROPOUT MIDDLE OUTPUT CURRENT CMOS VOLTAGE REGULATOR
S-1135 Series
Explanation of Terms
1. Low dropout voltage regulator
2. Output voltage (V
3. Line regulation
4. Load regulation (∆V
5. Dropout voltage (V
This IC’s voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
The accuracy of the output voltage is ensured at ±1.0% or ±15 mV

Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output
voltage changes due to a change in the input voltage with the output current remaining unchanged.
