1. All devices are 100% production tested at TA = +25 NC. Limits overtemperature are guaranteed by design and correlation.

2. The VC regulator is intended for internal use only as startup supply of PM8804; any additional external VC current, like the

external MOSFET driving current, has to be take in account in the dimensioning of the filter capacitor to be connected with

VC pin; VC regulator cannot supply continuously the specified max current limit.

3. Parameter guaranteed by design.
