What is the input voltage? Perhaps your problem isn’t voltage related, maybe the SX or the regulator just isn’t getting enough power or maybe there’s something else going on entirely. Yes, my password is: Post as a guest Name. I just thought the OKIsr might be a little overkill in terms of cost for other similar stuff down lm940 road.
As a general rule, the higher the voltage rating the larger the size so a lm240. Sometimes they refuse to power up too depending on the nature of your load, or have source voltage issues.
Do you already have an account? This capacitor must be rated over the same operating temperature range as the regulator and.
Jul 17, 22, 1, Posted by bobsuper in forum: You won’t have to worry about dropout until you get pretty far down there, l2940 you can use a super capacitor or battery to handle low voltage situations.
Anything with that rating or higher is fine. Hi Russel, thanks for the feedback.
Sign In or Register to comment. Does anyone have any ideas how I might stabilize this output? If there are mods, what would need to be changed? Whether this is really what they intend is unknown. If not then what am I looking for exactly. CuF is an SMD tant: Quick Links Categories Recent Discussions. I’m afraid to go further in the project attaching microcontroller, etc. Everything works until a cloud appears. Comments 9 Comments sorted by Date Added Votes.
Tom Wilson 68 7. Without the LED I measure 9.
What about with a simple ml2940 load at the same current, does it have the same problem? Sign up using Email and Password. The data sheet says the 22uF is required for stability. Voltage Regulator Question Posted by vwadad in forum: Dec 20, 10, 1, May be increased without bound to maintain regulation during transients.

The 10uf is on the input to the I have a project I am tinkering with that needs to run the SX28 at 50Mhz. Malware on Android Devices Mimics Hardware Specs and Wastes Billions of Dollars Ever wonder why so many Android apps ask users if they’d like to download obscure add ons like “smart charging”?
Nov 14, 8. Less crucial is a picture of the output voltage waveform especially as we don’t know what bad probing techniques you may have used. No, create an account now. Nov 13, 3.
Locate as close as possible to the regulator. Most low dropout regulators use a PNP transistor as its adjustable series resistance.
I have a bag of LM 5v here that I just stopped using because I got sick of their fussy operation. Is this the same when using an SX28? Nov 13, 4. Tying down what manufacturers really mean can be a challenge.
