*1. V_OUT(S): Set output voltage
V_OUT(E): Actual output voltage
The output voltage when V_IN = V_OUT(S) + 2.0 V, I_OUT = 10 mA
*2. The 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_IN1 is the input voltage at which the output voltage becomes 98% of V_OUT3 after gradually decreasing the input voltage.
V_OUT3 is the output voltage when V_IN = V_OUT(S) + 2.0 V, and I_OUT = 125 mA or 250 mA.
*4. Due to limitation of the power dissipation, this value may not be satisfied. Attention should be paid to the power
dissipation when the output current is large.
This specification is guaranteed by design.
