it can be a shunt regulator, and there is even a circuit for its use as a switching regulator in the data sheet. To fully understand the 723 then is to fully understand low voltage linear regulators.

There are two basic types of non-IC voltage regulators: switching types and all others, mainly linear and shunt types. Unlike a switching voltage regulator, a linear voltage regulator or shunt voltage ...

The circuit is centered around a TL431 programmable shunt regulator ... but it thrives on feedback. To make a voltage regulator from the LED circuit shown here, all you need to do is add a ...
