SUPER-LOW OUTPUT VOLTAGE LOW DROPOUT CMOS VOLTAGE REGULATOR
S-11L10 Series
Rev.1.0_00
„ Explanation of Terms
1. Low dropout voltage regulator
This IC’s voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
2. Output voltage (V_OUT)
The accuracy of the output voltage is ensured at ±1.0% or ±15 mV^*1 under the specified conditions of fixed input
voltage^*2, fixed output current, and fixed temperature.
*1. Differs depending on the product.
*2. When V_OUT < 1.5 V : ±15 mV, when 1.5 V ≤ V_OUT : ±1.0%
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.

Line regulation
 ^∆VOUT1 
∆V_IN•V_OUT 
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.
4. Load regulation (∆V_OUT2)
Indicates the dependency of the output voltage on the output current. That is, the values show how much the output
voltage changes due to a change in the output current with the input voltage remaining unchanged.
5. Dropout voltage (V_drop)
Indicates the difference between input voltage V_IN and the output voltage when; decreasing input voltage V_IN
gradually until the output voltage has dropped out to the value of 98% of output voltage V_OUT3, which is at V_IN =
V_OUT(S) + 1.0 V.
V_drop = V_IN1 − (V_OUT3 × 0.98)
