ILOAD < 1A, VOUT remains constant. 4. The output voltage level is VOUT = VREF (1 + (R1/R2)) where VREF = 0.8V (typical) and R2 = 10K. For VOUT = 1.2V, R1 is preset to 5K and for VOUT = 3.3V, R1 is preset to 31.25K. Note: R2 and R1 values are reversed for FAN2002MPX. 5. To verify supply current in "ON" and "OFF" modes; observe that, in shutdown mode, supply current drops below 1A and in "ON" mode, IQ < 50A. 6. If quiescent current is a key design parameter, a higher value feedback resistor R2 can be used, along with a small bypass capacitor CF (e.g. R2 = 100K and CF = 10pF). Figure 1.
