• 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

    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…

  • Frontend of LT3042/45

    According to figure 11 in the article here below;


    If switching power supply is do close to LT3042/45 regulator, adding or increasing input capacitor degrades the performance…

  • 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,



  • LT3042-Split Cap/Kelvin - Connections


      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…

  • 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…

  • RE: Utilizing the LT3045/LT3042 for post-regulating dc/dc switching converters

    I have no final answer to your question, but I do know for sure that AN-159:

    has some good hints for your application. It describes a similar setup (Buck followed…

  • Design information for "Ultralow 1/f Noise Reference Buffer " design using the LT3042

    I would like to implement the following application from the data sheet for a 2.5V output, as opposed to a 5V output.  Is there any design information available for this circuit?  And some analysis to explain how this circuit works to get rid of the 3042…

  • RE: Use of OP as high quality power supply?

    Hello Hans-Ludwig,

    without answering your question direct as I have not tried such a circuit: Let me point you towards the LT3042. This LDO has a tremendous PSRR AND Noise figure. And important as well: Its internal power switch is designed for a power…
