S-1740/1741 Series
Rev.1.1_00
 Explanation of Terms
1. Regulator block
1. 1 Output voltage (VOUT)
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 VOUT < 1.5 V: ±15 mV, when VOUT ≥ 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 Table 14 in " Electrical Characteristics" for details.

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.
1. 3 Load regulation (ΔVOUT2)
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.
1. 4 Dropout voltage (Vdrop)
Indicates the difference between input voltage (VIN1) and the output voltage when the output voltage becomes
98% of the output voltage value (VOUT3) at VIN = VOUT(S) + 1.0 V after the input voltage (VIN) is decreased
gradually.
Vdrop = VIN1 − (VOUT3 × 0.98)
