Regulator Bypass
Some applications may not require the use of all four regula-
tors provided in the A8450. For the regulators that are not
used, the corresponding external components are not needed.
If either or both of the two 5 V regulators are not required by
the application, bypass an unused regulator by not connect-
ing its output terminal, V5D or V5A. Also, the corresponding
output capacitor, C1 or C2, is not used.
For the 3.3 V regulator and the 1.2 V to 3.3 V adjustable
regulator, if either or both are not needed, the corresponding
external components are not used. In addition, if the 3.3 V
regulator is not used, CL33 and V33 are not connected. If the
adjustable regulator is not used, CLADJ and FB are not con-
nected. However, to ensure stability of the A8450, the base
drive pin, V33BD or VADJBD, of any unused regulator must
be shorted to VREG.
