Typical Applications (Continued)
The LP2951 can be reconfigured to an adjustable type regu-
lator, which means the LMC7660 can give a regulated output
from −2.0V to −10V dependent on the resistor ratios R1 and
R2, as shown in Figure 13, V_ref = 1.235V:
*For lower voltage operation, use Schottky rectifiers
