‡
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
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.
NOTE 2: Minimum input voltage is 3.5V or Vo(typ) + 1V whichever is greater.
The minimum value of 3.5 V is the absolute lower limit for the recommended input voltage range for the TPS73HD301.
