Part Number: TPS74801

Hi BU expert,

What is the difference between QFN, DFN and WSON?

BTW, can you recommend a LDO for VIN=3.3V, VOUT=2.2V, accuracy≤1%，Iout is no more than 1A LDO? Thanks.

Regards，

Charlie

Vin(Max)(V)	6
Vin(Min)(V)	0.8
Vout(Max)(V)	3.6
Vout(Min)(V)	0.8
Fixed output options(V)	---
PSRR @ 100 KHz(dB)	30
Noise(uVrms)	7
Accuracy(%)	0.85
Dropout voltage (Vdo)(Typ)(mV)	75
Iq(Typ) (mA)	0.55
Output capacitor type	Ceramic
Thermal resistance θJA(°C/W)	47.2
Operating temperature range(C)	-40 to 125
Package size: mm2	9 mm2: 3 x 3 (VSON\|10)
