CIRCUIT DESCRIPTION
ENABLE Function
By pulling the V REF /ENABLE lead below 2.0 V typically,
(see Figure 10 or Figure 11), the IC is disabled and enters a
sleep state where the device draws less than 55 m A from
supply. When the V REF /ENABLE lead is greater than 2.75 V,
V OUT tracks the V REF /ENABLE lead normally.
Output Voltage
The output is capable of supplying 200 mA to the load
while configured as a similar (Figure 7), lower (Figure 9), or
higher (Figure 8) voltage as the reference lead. The Adj lead
acts as the inverting terminal of the op amp and the V REF
lead as the non ? inverting.
The device can also be configured as a high ? side driver as
displayed in Figure 12.
