†
CSR (compensation series resistance) refers to the total series resistance, including the equivalent series resistance (ESR) of the capacitor, any
series resistance added externally, and PWB trace resistance to C
L
.
‡
Pulse-testing techniques are used to maintain virtual junction temperature as close as possible to ambient temperature; thermal effects must
be taken into account separately.
§
Pass-element series resistance measured with sense pin disconnected from output to allow output voltge to rise to full saturation.
