Re: LM350 Help
The LM350, or any other voltage regulator, can deliver the rated output current under the condition that the input regulated/unregulated source can supply voltages ≥ (Vout+3V) @ the required output current ..
If the input condition is not fulfilled then don't expect the output to follow anything ..
Big input smoothing capacitors may help for some ms, but they will not provide power for ever ..
Ensure that the unregulated side can supply sufficient current and you will be OK ..
