CSR refers to the total series resistance, including the ESR of the capacitor, any series resistance added externally, and PWB trace resistance
to CO.
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.
§This voltage is not recommended.
Output voltage programmed to 2.5 V with closed-loop configuration (see application information).
NOTES:
2. When VI < 2.9 V and IO > 100 mA simultaneously, pass element rDS(on) increases (see Figure 10) to a point such that the resulting
dropout voltage prevents the regulator from maintaining the specified tolerance range.
3. To calculate dropout voltage, use equation:
VDO = IO
rDS(on)
rDS(on) is a function of both output current and input voltage. The parametric table lists rDS(on) for VI = 2.4 V, 2.9 V, 3.9 V, and
5.9 V, which corresponds to dropout conditions for programmed output voltages of 2.5 V, 3 V, 4 V, and 6 V, respectively. For other
programmed values, refer to Figures 10 and 11.
