Can I simulate LT83402 output noise spectrum density using tran and FFT?

Category: Software
Product Number: LT83402
Software Version: LTspice version 26.0.1

I ran LTspice trasient simulation (.tran 0 1m 900u 0.1n) using .options plotwindsize=0 numdigit=15 trtol=0.1 chgtol=1e-16 vntol=1e-9.

And applied FFT to transient simulation output result.

However noise flower in FFT plot is much higher than I expected (from datasheet noise spectrum density plot)

Can I use LTspice transient simuation and FFT fot noise density simulation?
