5.5 V INPUT, 100 mA CMOS VOLTAGE REGULATOR WITH 0.35 μA SUPER LOW CURRENT CONSUMPTION
S-1317 Series
Rev.1.0_00
 Explanation of Terms
1. Output voltage (V_OUT)
This voltage is output at an accuracy of ±1.0% or ±15 mV^*2 when the input voltage, the output current and the
temperature are in a certain condition^*1.
*1. Differs depending on the product.
*2. When V_OUT < 1.5 V: ±15 mV, when V_OUT ≥ 1.5 V: ±1.0%
Caution If the certain condition is not satisfied, the output voltage may exceed the accuracy range of
±1.0% or ±15 mV. Refer to " Electrical Characteristics" for details.
2.
Line regulation
 ^ΔVOUT1 
ΔV_IN • V_OUT 
Indicates the dependency of the output voltage against the input voltage. The value shows how much the output
voltage changes due to a change in the input voltage after fixing output current constant.
3. Load regulation (ΔV_OUT2)
Indicates the dependency of the output voltage against the output current. The value shows how much the output
voltage changes due to a change in the output current after fixing input voltage constant.
4. Dropout voltage (V_drop)
Indicates the difference between input voltage (V_IN1) and the output voltage when the output voltage becomes 98%
of the output voltage value (V_OUT3) at V_IN = V_OUT(S) + 1.0 V after the input voltage (V_IN) is decreased gradually.
V_drop = V_IN1 − (V_OUT3 × 0.98)
