Simple voltage regulator oscillator

[kooler]

haha..
you need to look here..  http://www.energeticforum.com/renewable-energy/7410-simple-voltage-regulator-oscillator.html

we all look at to many forums and get confused sometimes..
he doesn't post here under his lidmotor name..

robbie

ps.. the L4931 with a drop out voltage of 0.4v doesn't work..

Thanks robbie!

All,

The National Semiconductor Applications Note on the original LM78xx
regulator showed how to build a switching regulator by adding only
an inductor to this three terminal voltage regulator, to increase it's
regulation efficiency. So I think rational astable operation will
generally be a competitive attribute of any three terminal regulator.

Hi.Here is an update for my Voltage regulator oscillator.In this configuration it can be used up to the maximum rated input of the TS 2950 regulator and the full output voltage is available for switching or pulsing applications.Jonny.
