REGULATING V
It is possible to regulate the output of the LM2662/LM2663 by
use of a low dropout regulator (such as LP2986). The whole
converter is depicted in Figure 8. This converter can give a
regulated output from −1.5V to −5.5V by choosing the proper
resistor ratio:

The error flag on pin 7 of the LP2986 goes low when the reg-
ulated output at pin 5 drops by about 5% below nominal. The
LP2986 can be shutdown by taking pin 8 low. The less than
1 μA quiescent current in the shutdown mode is favorable for
battery powered applications.
