Although TRF372017 has a Power Saving mode(1-Pin), when changing this function to low/High, how much is speed of response?

It was not found out of the data sheet.
If there is any information, please let me know.

The PS (powersave) control turn-on transient with SPEEDUP enabled is around 1us. The plot below shows 1.4us turn-on (PS high -> low), but the trigger pulse fall time accounts for some of this response time.

Without SPEEDUP, the turn-on is very slow, around 80us. In this situation, the bias stabilization cap in the divider stage requires a long charge time. This response is also shown along with the block diagram of the stabilization capacitor from the datasheet.

Turn off (PS low -> high) times are near 1us for both SPEEDUP conditions.
