Part Number: LM317A We would like to use LM317A for the application which has 12V Vin and 3.3V Vout for 1.0A Iout. We tried LM317A with the EVM (LM317A-337N-EVM), however, we found out that when we started applying the load from 0.1A to 1.0A, we saw that…
Part Number: LM317A Other Parts Discussed in Thread: LM137 , LM317 Team,
Can you please help with the below question?
We are using your Evalution Board LM317A-337N-EVM to test the ripple rejection. We are interested in reproduce the data of ripple rejection…
Hi Leo,
The best EVM to use to kickstart an evaluation on the adjustable version of TLV1117 is LM317A-337N-EVM. The boards you mention can be modified to work with an adjustable device; however, LM317A-337N-EVM is already has pads for the adjustable…
Hi Ogasawara,
The amount of capacitance required for your application will depend on your application specific conditions and application specific performance requirements. LM317A will achieve the best performance with solid tantalum capacitors due to…
Hi Santosh,
LM317 and LM337 go well together as positive and negative votlage rail regulations. Both of these devices are available for up to 1.5A load current in many package options.
The evaluation module of both devices is available at this link…
Hi Takahiro,
Please find the startup for the LM317A bellow taken from the EVM User's Guide. While this is for a 5 V output, the startup time will be similar for the 3.3 V output due to the fact that the output is a gained version of the internal reference…
HI Mark,
I understand what you are trying to achieve here. LM1084 will not work as negative regulator from a negative input voltage. You need to use LM317N and LM337N devices for positive and negative rail regulation. They are available in wide range…
