Applications Information
The voltage rating of the output capacitor should be 10V or
more. All other capacitors should have a voltage rating at or
above the maximum input voltage of the application.
CIRCUIT BOARD LAYOUT
For optimal, low-noise performance, all capacitors (C
C
A solid ground plane should be used for IC and component
GND connections. Refer to the LM27961 Evaluation Board
for an example layout.

MICRO SMD MOUNTING
The LM27961 is an 18-bump micro SMD with a bump size of
approximately 300 micron diameter. The micro SMD pack-
age requires specific mounting techniques detailed in Na-
tional Semiconductor Application Note 1112 (AN-1112).
