Data Sheet
Fig. 17: Turn-on transient for Vout = 3.3 V with the application of
SEQ/ENA signal at full rated load current (resistive) and 1 μF external
capacitance at Vin = 12 V. Top Trace: SEQ/ENA Signal (5 V/div.);
Bottom Trace: Output Voltage (1 V/div.); Time Scale: 1 ms/div.
Fig. 18: Turn-on transient for Vout = 3.3 V and 5.0 V with the
application of SEQ/ENA signal at full rated load current (resistive) and
1 μF external capacitance at Vin = 12 V. SEQ/ENA pins are tied
together. Top Trace: SEQ/ENA Signal (5 V/div.); Middle Trace: Output
Voltage of 5V POL (2V/div.); Bottom Trace: Output Voltage of 3.3V
POL (2 V/div.); Time Scale: 2 ms/div.
Fig. 19: Turn-on transient for Vout = 3.3 V with the application of the
input voltage at full rated load current (resistive) and 1 μF external
capacitance at Vin = 12 V. Top Trace: Input Voltage Signal (5 V/div.);
Bottom Trace: Output Voltage (1 V/div.); Time Scale: 1 ms/div.
Fig. 20: Turn-off transient for Vout = 3.3 V and 5.0 V with the removal
of SEQ/ENA signal at full rated load current (resistive) and 1 μF
external capacitance at Vin = 12 V. SEQ/ENA pins are tied together.
Top Trace: SEQ/ENA Signal (5 V/div.); Middle Trace: Output Voltage
of 5V POL (2V/div.); Bottom Trace: Output Voltage of 3.3V POL (2
V/div.); Time Scale: 2 ms/div.
