Hi, 

We are using LT3094 to generate -5v 20ma from - 12v. 

We made an error on the pcb that the thermal pad is floating instead of connected to input.

Meanwhile we got - 5v at the output.

Is there any performance degradation in this case? 

Thanks. 

Hello;

i succeed to get positive and negative 12V with the ciruit here below but i need 24v output. Is there any way that you show me lt spice model to do that.

Best Regards...

Hi,

I would like to use LT3094/LT3045-1 for positive and negative power supply. The output voltage is +- 12V but the input may be +-15V or +-18V. We are considering putting a heat sink beneath the LDOs (i.e., on the 4th layer).

But the reference designs…

Hi,

The recommended PCB designs for LT3045 and LT3094 are presented in the form of two separate PCBs. In my project I would like to place both regulators on one board. My question concerns the GND planes on layers L2 and L3. Should the planes on each…

Would like to use an LT3045 and LT3094 as tracking linear post-regulators to generate +/-3-6V supplies (that track eachother) - with a high-speed opamp (e.g. AD8610 or AD4625-1) in the feedback loop. Are there any special precautions in doing so?

The LT3042, LT3045... (all positive LDOs of that family) note that some fraction (1:400 or 1:500, depending on max current) of the output current is sourced from the ILIM pin.

Given that the LT3094 is from the same family and the block diagram looks similar…

How to use a PCB trace to create the ballast resistors in the layout? In my board the regulator outputs are directly going to a power plane through a via at the regulator output. Should the traces be placed before the via? Can anyone share a sample layout…

Is there any plans to support the below signal chain power?

• (50Hz AC) -> (LT4320) -> (LT3081) -> (LT3045)
• (50Hz AC) -> (LT4320) -> (LT3091) -> (LT3094)

Preferably with room for large bulk caps in all three stages

The reason is, it…
