Board Layout
When designing a board, use the following guidelines:
1) The R
SET
connection to the ISET pin is a high-imped-
ance node, and sensitive to layout. Place R
SET
right
next to the ISET pin and route R
SET
directly to these
pins with very short tracks.
2) Ensure that the track from the ground end of R
SET
routes directly to GND pin 18 (PDIP package) or
GND pin 16 (SSOP package), and that this track is
not used as part of any other ground connection.
