VOUT(S): Specified output voltage VOUT(E)1: Actual output voltage at the fixed load The output voltage when fixing IOUT( = 30 mA) and inputting VOUT(S) + 1.0 V VOUT(E)2: Actual output voltage at the fixed load The output voltage when fixing IOUT( = 80 mA) and inputting VOUT(S) + 1.0 V *2. The output current at which the output voltage becomes 95% of VOUT(E)1 after gradually increasing the output current. *3. Vdrop = VIN1 − (VOUT3 × 0.98) VOUT3 is the output voltage when VIN = VOUT(S) + 1.0 V and IOUT = 100 mA. VIN1 is the input voltage at which the output voltage becomes 98% of VOUT3 after gradually decreasing the input voltage. *4. The change in temperature [mV/°C] is calculated using the following equation. [] [ ] [] 1000 C ppm/ V Ta V V V C mV/ Ta V OUT OUT OUT(S) OUT ÷ ° • ∆ ∆ × = ° ∆ ∆ 3 * 2 * *1 *1. The change in temperature of the output voltage *2. Specified output voltage *3. Output voltage temperature coefficient *5. The output current can be at least 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. |
