5. The module is capable of both sinking and sourcing
current when following a voltage at its track input.
Therefore startup into an output prebias is not supported
when the module is under Auto-Track control. Note: A
pre-bias holdoff is not necessary when all supply voltages rise
simultaneously under the control of Auto-Track.
6. The Auto-Track function can be disabled by connecting
the Track pin to the input voltage (V
I). With Auto-Track
disabled, the output voltage will rise at a quicker and
more linear rate after input power is applied.
