*1. V_OUT(S): Set output voltage
V_OUT(E): Actual output voltage
Output voltage when fixing I_OUT (= 100 mA) and inputting V_OUT(S) + 1.0 V
*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_OUT3 is the output voltage when V_IN = V_OUT(S) + 1.0 V and I_OUT = 300 mA, 1000 mA.
V_IN1 is the 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.
ΔV_OUT
ΔTa
[mV/°C]^*1 = V_OUT(S) [V]^*2 ×
ΔV_OUT
ΔTa•V_OUT
[ppm/°C]^*3 ÷ 1000
*1. Change in temperature of the output voltage
*2. Set output voltage
*3. Output voltage temperature coefficient
*5. The output current can be at least this value.
Due to limitation of the package 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.
