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 m 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 non ? inverting.
The device can also be configured as a high ? side driver as
displayed in Figure 18.

* C1 is required if the regulator is far from the power source filter. In case of power supply generates voltage ripple (e.g. DC-DC con-
verter) a passive low pass filter with C1 value at least 1 m F is required to suppress the ripple. The filter should be designed according
to particular operating conditions and verified in the application.
** C2 is required for stability.
*** C3 is recommended for EMC susceptibility
