9 / 44 page  Revision 1.0 9 www.national.com 6.0 Electrical Specifications (Continued) Note: The voltage regulators are optimized for the internal operation of the LMX9820A. Because any noise coupled into these supplies can have influence on the radio perfor- mance, it is highly recommended to have no additional load on their outputs. 6.2 DC CHARACTERISTICS Table 12.
