UNIT

DC line regulation

On mode, VIN = VINmin to VINmax at IOUT = IOUTmax

Transient load regulation

On mode, VIN = 2.7 V, VOUTtyp = 1.8 V

IOUT = 0.1 × IOUTmax to 0.9 × IOUTmax in 5 µs

and IOUT = 0.9 × IOUTmax to 0.1 × IOUTmax in 5 µs

Transient line regulation

On mode, VIN = VINmin + 0.5 V to VINmin in 30 µs

and VIN = VINmin to VINmin + 0.5 V in 30 µs, IOUT = IOUTmax / 2

0.2

Turnon time

VOUT = (1 to 1.8 V), at IOUT = 0

measured from VOUT = 0.1 V up to 97% of VOUT

150

µs

VOUT = (1.9 to 3.3 V), at IOUT = 0

measured from VOUT = 0.1 V up to 97% of VOUT

Ripple rejection

VIN = VINDC + 100 mVpp tone,

VINDC+= 3.8 V,

IOUT = IOUTmax / 2

ƒ = 217 Hz

ƒ = 50 kHz
