CIRCUIT DESCRIPTION
ENABLE Function
By pulling the V
REF
/ENABLE lead below 0.8 V, (see
Figure 16 or Figure 17), the IC is disabled and enters a sleep
state where the device draws less than 20 A from supply.
When the V
REF
/ENABLE lead is greater than 2.1 V, V
OUT
tracks the V
REF
/ENABLE lead normally.
Output Voltage
The output is capable of supplying 70 mA to the load
while configured as a similar (Figure 13), lower (Figure 15),
or higher (Figure 14) voltage as the reference lead. The Adj
lead acts as the inverting terminal of the op amp and the
V
REF
lead as the noninverting.
The device can also be configured as a highside driver as
displayed in Figure 18.
