is there any model for the ADP1708 LDO IC??
Supercapacitor assisted low dropout regulator is a new approach to develop high efficiency DC-DC converters with supercapacitors used for energy recovery. One limitation in these topologies is that in some configurations a large number of low-speed switches are required.
Apology for this extreme delay. Unfortunately, this part has never made it to top list. I have raise this concern and we will find a way to get LTspice models to many of our parts. The best way for now is to have a demo board if you want to test critical items like PSRR, noise, load transient. If you need urgently, you can also request data through a local ADI sales or FAE.
