Ideas.....(design idea added 11/05) This Design Idea shows how adding one or
two passive parts can reduce a hysteretic constant-on-time switched-mode voltage
regulator's output voltage ripple and reduce its susceptibility to variations in
external load capacitance and ESR (equivalent series resistance). The regulator
operates much.... |

Amperage Booster for 78xx's - Volt regulators such as the LM708, and LM317
series (and others) sometimes need to provide a little bit more current then they
actually can handle. If that is the case, this little circuit can help out.
A power transistor such as the 2N3772 or similar can be used (See the project on
the 3-part variable power supply).….(Tony van Roon's electronic schematic /
