NOTES: 
1.  These values apply at minimum input voltage conditions. 
2.  The stated voltages refer to system in LINE-UP mode with a fully charged battery.  If the battery has 

been recently discharged the system will operate in current limited mode until the battery regains full 
charge.  When the battery is less than fully charged, the output voltage will be lower than the stated 
values.  In LINE-DOWN mode, the load voltage is roughly equal to the battery voltage.  Battery voltage 
will be a function of state of charge, temperature and overall condition.  In both modes of operation 
the LOAD voltage will be as much as 0.2 Volts (0.4 Volts for 24 Volt systems) lower than the battery 
voltage because of the parasitic voltage drop across the output switch. 

3.  The system battery has a significant damping effect on noise; typical output noise will be much lower.
