APPLICATION INFORMATION (continued)

Figure 23. Adding Hysteresis

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.
