Hi team,

Could you please give me a scope shot of Vout=3.3V power up by EN?

I expects the 3.3V version of Figure 8-8.

Hello Shinji,

I took some scope data for Vout=3.3V, Vin=12V, Ven=5V and Iout=100mA. My Cin=2.2uF and Cout=10uF in this scope shot. The output shows a very similar behavior to Figure 8-8, please see below:

Regards,

Andres
