C
Only parts in bold have CSLEW pin.
(Not available in 5-pin SOT-23 packages).
The C
output voltage ramp at turn-on. This input allows
designers the option of decreasing the output’s slew rate
(slowing the voltage rise) by adding an external
capacitance between the C
capacitance slows the rate at which the pass FET gate
voltage increases and thus, slows both the response to
an Enable command as well as V
value.
Figure 8 illustrates effect of C
output rise time.
