• Manufacturer: ON Semiconductor

ENABLE Function
(see Figure 10 or Figure 11), the IC is disabled and enters a
sleep state where the device draws less than 55 mA from
supply. When the V

** C2 is required for stability.
*** C3 is recommended for EMC susceptibility.
* C1 is required if the regulator is far from the power source filter.

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
lead as the non−inverting.

The output is capable of supplying 200 mA to the load
The device can also be configured as a high−side driver as
