Lm723 application notes

not be well regulated. Note that a 10 mA programming current is used since lab supplies are often used with no-load, and the LM317 requires a worst-case minimum load of 10 mA. The 1.2V minimum output of the LM117 makes it easy to design power supplies with electrical shut-down. At 1.2V, most circuits draw only a small fraction of their normal oper- Final Notes. For now, I can say that my goal of a compact, lightweight amplifier capable of at least 1 kW output is a reality. The SSKW has served me well in its intended DXpeditionary application. Nonetheless, the amplifier in its present form is still experimental.
