Analog Power Signal Routing
All power inputs should be tied to the main VDD source (i.e.
battery), unless the user wishes to power it from another
source. (i.e. powering LDO from Buck output).
The analog VDD inputs power the internal bias and error am-
plifiers, so they should be tied to the main VDD. The analog
VDD inputs must have an input voltage between 2.8 and 5.5
V, as specified in the Electrical Characteristics section of this
datasheet.
The other Vins (VINLDO1, VINLDO2, VIN1, VIN2) can actu-
ally have inputs lower than 2.8V, as long as it's higher than
the programmed output (+0.3V, to be safe). The analog and
digital grounds should be tied together outside of the chip to
reduce noise coupling.
For more information on board layout techniques, refer to Ap-
plication Note AN–1187 “Leadless Lead frame Package
(LLP)” on http://www.national.com This application note also
discusses package handling, solder stencil and the assembly
process.
