This section provides typical performance waveforms for the TLV70528EVM (with the 2.8-V version of the
TLV705xx device installed).
4.1 Turn-On Sequence
Figure 1 shows the turn-on/-off characteristic where VIN is pre-set to 5.0 V, the output drives a full load,
and the EN turn-on is stepped to 3.2 V (C2, white). The output soft start (C1, yellow) shows a monotonic
rise time of approximately 50 μs after a built-in delay of approximately 70 μs. The output voltage startup
ramp does not depend on the load.

4.2 Output Load Transient
Figure 2 illustrates the load transient responsefor a full load step transient from 1 mA to 200 mA. VIN is
set at 5 V.
