The Boldface applies over -40oC ≤T J≤125 oC. (P ≤maximum power dissipation.) Note 2: For the details of VIN range, please refer to (VIN-VOUT)*ILOAD≤maximum power dissipation (Figure 4). Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value which is measured at VOUT+1V applied to VIN. Note 4: VIN=VOUT(NOMINAL)+1V. Note 5: VEN ≤0.8V, VIN≤8V, VOUT=0V. |
