NOTE
• Power up (Start up): This curve shows the input voltage required to achieve the 5 V regulation
during power up over the range of load currents (see Figure 10).
• Power down (Tracking): This curve shows the input voltage at which the output voltage drops
approximately by 0.7 V from the programmed 5 V regulated voltage (see Figure 10) or for low
input voltages (tracking function) over the range of load currents (see Figure 9).
• In Figure 5 and Figure 6, L and C are output inductor and capacitor respectively.
