5.0 TYPICAL CHARACTERISTICS (CONTINUED)

Drive High Delay

Drive Low Delay

VIN steps from 0.8V to 5V

See application circuit on Page 5

ILOAD = 200mA

Trace 1: VIN stepping for 0.8V to 5V

Trace 2: DR

TH(HI)

TDH = < 4 S

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 – 3A charging a 1500µF capacitor

Trace 2: DR going high at VTH(HI)

Trace 3: VOUT, offset 3.3V. VOUT(min) = 3.24V

ILOAD = 200µA

Trace 1: VIN stepping for 5.5V to 0V

R

TDL = < 600nS

VO (min) with VIN Falling

VOUT voltage difference is IOUT x RDS(ON) + voltage

difference from LDO to VAUX supply

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 = 200µA
