*1. V_OUT(S) : Specified output voltage
V_OUT(E) : Actual output voltage at the fixed load
Output voltage when fixing I_OUT (= 30 mA) and inputting V_OUT(S) + 1.0 V
*2. Output current at which the output voltage becomes 95% of V_OUT(E) after gradually increasing the output current.
*3. V_drop = V_IN1 − (V_OUT3 × 0.98)
V_OUT3 : Output voltage when V_IN = V_OUT(S) + 1.0 V and I_OUT = 100 mA
V_IN1 : Input voltage at which the output voltage becomes 98% of V_OUT3 after gradually decreasing the input voltage
*4. The change in temperature [mV / °C] is calculated using the following equation.

*1. Temperature change ratio of the output voltage
*2. Specified output voltage
*3. Output voltage temperature coefficient
*5. The output current can be supplied at least to this value.
Due to restrictions on the package power dissipation, this value may not be satisfied. Attention should be paid to the
power dissipation of the package when the output current is large.
This specification is guaranteed by design.
