CSR refers to the total series resistance, including the ESR of the capacitor, any series resistance added externally, and PWB trace resistance
to C
o
.
‡
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.
§
Dropout test and pass-element series resistance test are not production tested. Test method requires SENSE terminal to be disconnected from
output voltage.
