2.9 Start-Up
The start-up voltage waveform of the SLVP215 is shown in Figure 2–12. There
is approximately a 9-ms delay after the input voltage rises above the 2.9-V
start-up voltage threshold until the output voltage begins to ramp up to the final
value of 1.25 V. The output voltage tracks the greater of the internal and
external slow-start voltages, accounting for the change in ramp rates .
