TYPICAL CHARACTERISTICS (CONTINUED)
Trace 1: VIN stepping for 0.8V to 5V
Trace 2: DR
TH(HI)
TDH = < 4 S
Drive High Delay
See application circuit on Page 5
ILOAD = 200mA
VIN steps from 0.8V to 5V
Trace 1: VIN – 3A charging a 1500µF capacitor
Trace 2: DR going high at VTH(HI)
Trace 3: VOUT, offset 3.3V. VOUT(min) = 3.24V
ILOAD = 20mA
VO (min) with VIN Rising
Notice no voltage spikes during transition
from VAUX to LDO output
VOUT voltage difference is IOUT x RDS(ON) and variations
between VAUX supply and LDO output voltage
Trace 1: VIN stepping for 5.5V to 0V
R
TDL = < 600nS
Drive Low Delay
Trace 1: VIN – discharging a 1500µF capacitor
Trace 2: DR going low at VTH(LO)
Trace 3: VOUT, offset 3.3V. VOUT(min) = 3.14V
ILOAD = 20mA
VO (min) with VIN Falling
VOUT voltage difference is IOUT x RDS(ON) + voltage
difference from LDO to VAUX supply
