sets the value of the transition voltage required to switch the comparator output by increasing the
threshold region, thereby reducing sensitivity to noise.
The low power consumption and 1.8-V supply voltage of the TLV3011 make it an excellent candidate for
battery-powered applications. Figure 24 shows the TLV3011 configured as a low battery level detector for a 3-V
battery.
