† 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.

§ Output voltage programmed to 2.5 V with closed-loop configuration (see application information).

NOTES:

1. When VI < 2.9 V and IO > 150 mA simultaneously, pass element rDS(on) increases (see Figure 27) to a point such that the resulting

dropout voltage prevents the regulator from maintaining the specified tolerance range.

2. To calculate dropout voltage, use equation:

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, see Figure 26.)
