The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up.

They are ideal for situations where the input voltage is not tightly controlled. The output control pin makes the device particularly suitable for Flash PROM applications where an on/off controlled voltage source is required.
