Part Number: LM237 Hi TIer,
Could you provide a certificate of origin for LM237KCSE3? My customer would like to know LM237KCSE3 made in which country, thank you.
Part Number: LM237 Other Parts Discussed in Thread: LM1085 , Hello E2E,
Our customer is planning to about add the ON/OFF circuit for LM237. They looked LM1085 datasheet. That linear regulator can about add the ON/OFF circuit on external, figure17. …
I think I figured it out. The folder wasnt visible but as soon as I took out the LIB file and moved it to my desktop the New Macro Wizard could find it and then I was able to use the Insert Macro from there.
Thanks
Hi Mike,
John is correct, there is not a negative LDO with 5A current limit. The LM137, LM337, LM120, LM237, UA79, LM79, LM320 and LM120 all provide 1.5A of current on a negative rail.
You would need to float the positive LDO if you were to use it…
Hi Adrian,
Thank you for your inquiry.
Can you clarify your output current requirements? Is it 0.3A?
If it is lower (like say 150mA) I wanted to quickly highlight a device that does both the +/- rails in a single package: TPS7A39.
However if…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
