Typical Characteristics (continued)

at operating temperature range TJ = 25°C, VIN = VOUT(NOM) + 0.5 V or 1.5 V (whichever is greater), IOUT = 1 mA, VEN = VIN, and

CIN = COUT = 1 μF (unless otherwise noted)

Figure 20. tPGDL vs Temperature

Figure 21. VEN(HI) and VEN(LO) vs Temperature

VEN = 5.5 V

Figure 22. IEN vs VIN

Figure 23. 3.3-V Foldback Current Limit vs IOUT

VOUT = 0.55 V, IOUT = 1 mA, VIN slew rate = 1 V/µs
