... V = +6.0V. IN(MAX) Rev. 8/21/01 Soft Start Condition The soft start feature of the SP2525 device is implemented by holding the output turn on rise time to 1ms. When off, the device has high impedance MOSFET channels that slowly be- come low impedance as the device powers on. This prevents an inrush current from causing voltage drops that result from charging a capaci- tive load ...
