• LT3042 long term drift

    LT3042 and more powerful LT3045 provide outstanding noise performance but their documentation say nothing about long term drift or noise behavior below 10Hz. What values of these characteristics may user expect?

  • LT3042 current monitoring

    Hello.
    I ask about the current monitoring function with the ILIM pin of the LT3042.
    1/400 of the VOUT pin currennt outputs from ILIM pin.
    What is the accuracy of this 1/400?
    The usage conditions are as follows.
    Vin = 16 V Vout = 2 V to 15 V Iout = 0 to 200…

  • LT3042 SET Pin Setting

    Dear All:

    The LT3042 datasheet Table 1. is VOUT Voltage setting table ,this table show VOUT (V) 15V,12V,5V,3.3V,2.5V but I need 1.8V, 1.5V, 1.2V, 1.0V RSET resistors is how much?

    Best Regards,

    Jacky

  • LT3042-Split Cap/Kelvin - Connections

    Hello,

      I am using the LT3042 for an ultra-clean 5V supply.  In working to get the best performance I have followed the Appnote for the Demo Board, DC2246B regarding the Split Cap design.

    My question is whether Pad 1 which connects to the GND Side of…

  • RE: Lt3042, LT3045 Vout set by DAC

    The challenge with using LT3042/5 is that the SET pin voltage rises to the same level as the OUT voltage. If the adjustment range is too large, then you will end up needing devices with higher voltage ratings.

    Two possible approaches I've used before…

  • LT3042 PG pin maximum current

    What is the maximum current allow through the open collector PG pin? Nothing is stated in the datasheet. It looks like 100uA has been used for curves and examples.

  • LT3042/LT3045 with 24 Volt Output?

    Hello from Germany,

    I am looking for an ultra low noise voltage regulator with 24V (and -24V) output. Would it be possible to cascade two LT3042/3045 (and the same with LT3094) which are set to 12V output to get 24V? Like two batteries added serially…
