VOUT(S) : Set output voltage VOUT(E) : Actual output voltage Output voltage when fixing IOUT ( 100 mA) and inputting VOUT(S) 1.0 V or 5.5 V *2. The output current at which the output voltage becomes 95% of VOUT(E) after gradually increasing the output current. *3. Vdrop VIN1 (VOUT3 0.98) VOUT3 is the output voltage when VIN VOUT(S) 1.0 V or 5.5 V, and IOUT 300 mA or 1000 mA. VIN1 is the input voltage at which the output voltage becomes 98% of VOUT3 after gradually decreasing the input voltage. *4. A change in the temperature of the output voltage [mV/°C] is calculated using the following equation. VOUT Ta [] mV/°C *1 = VOUT(S) [] V *2 VOUT TaVOUT [] ppm/°C *3 1000 *1. Change in temperature of output voltage *2. Set 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. |
