6.6 Switching Characteristics

Unless otherwise noted, the typical characteristics in the following table apply to an input voltage of 3.6V, an ambient temperature of 25°C, and a load of CL = 0.1 µF, RL = 100 Ω
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
tON Turn ON Time VIN = 5.0 V 1950 µs
VIN = 3.6 V 1750 µs
VIN = 1.8 V 1500 µs
tR Output Rise Time VIN = 5.0 V 1280 µs
VIN = 3.6 V 1100 µs
VIN = 1.8 V 750 µs
SRON Turn ON Slew Rate VIN = 5.0 V 3.2 mV/µs
VIN = 3.6 V 2.7 mV/µs
VIN = 1.8 V 1.8 mV/µs
tOFF Turn OFF Time VIN = 1.8 V to 5.0V RL = 100Ω, CL = 0.1uF 6 µs
tFALL Output Fall Time (2) RL = 100Ω CL = 0.1uF, RQOD  = Short 10 µs
RL = Open (1) CL = 10uF, RQOD  = Short 0.4 ms
CL = 10uF, RQOD  = 100 Ω 3.5 ms
CL = 100uF, RQOD  = Short 4 ms
(1) See the Timing Application section for information on how RL and CL affect Fall Time.
(2) Output may not discharge completely if QOD is not connected to VOUT
