| Modern day 723 and 78xx for new design |
| (1/6) > >> |
| tkamiya:
In old days, if one was making power supply, he/she used 723 or 78xx. But both of those series are quite dated. What's the modern day equivalent? I need a low noise/ripple 24V 3A power supply. |
| Wolfgang:
I had the same question. All the "good" new ICs are for lower voltages. If you find a *real* replacement for a 723, please tell me ! (but dont forget, I need 40V input, 150mA, ...). |
| SiliconWizard:
Quite a few. Just to mention LT/AD: https://www.analog.com/en/parametricsearch/11536 Eg: https://www.analog.com/en/products/lt1084.html https://www.analog.com/en/products/adp7142.html Now for those saying they are too pricy, go have a look at Alpha&Omega stuff. ;D |
| Wolfgang:
... not even close. Where are the following 723 features: - reference can be filtered - long term drift spec - settable current limit - configurable compensation - flexilibility to be used a spositive, negative, floating, ... regulator. Why people still work with the 723 is: - extremely flexible - stable - cheap like hell. 10€Cents in quantities, all "replacements" are some €. |
| iMo:
723 works as a switcher too.. |
