Typical start up times for this series, with a typical input voltage rise time of 2.2μs and output capacitance of 470μF (3.3, 5V outputs) and 220μF (12V outputs), are

shown in the table below. The product series will start into the maximum output capacitance with increased start times.

Maximum output capacitance should not exceed:

Typical Wave Form:
