Figure 3.7 5V only operation
While the standard application circuit is limited to roughly 5.5V lower supply voltage, a 5V only
application lets the IC run from a normal 5V +/-5% supply. In this application, linear regulator drop
must be minimized. Therefore, the major 5V load is removed by supplying VCC directly from the
external supply. In order to keep supply ripple away from the analog voltage reference, 5VOUT should
have an own filtering capacity and the 5VOUT pin does not become bridged to the 5V supply.
