5 / 19 page © 2009 Fairchild Semiconductor Corporation www.fairchildsemi.com FPF2300/02/03 • Rev. 1.1.3 5 Electrical Characteristics IN = 1.8 to 5.5V, TA = -40 to +85°C unless otherwise noted. Typical values are at IN = 3.3V and TA = 25°C. Note: 5. FPF2303 has a 10ms startup FLAGB blanking time when the part is turned on via the ON pin to ensure transient load currents settle. Figure 6.
