Apologies for the delayed response. PBFG is not a valid suffix for the LT1460 family. The LT1460 product page has all the valid part numbers listed in the ordering guide under the Sample and Buy section here .
我在使用LTLT1963AES8-3.3芯片时，遇到如下问题。电路的目的是通过STM32 MCU单片机的I/O控制LTLT1963AES8-3.3的SHUT 管脚，STM32 MCU单片机的I/O (PSW_1)配置成开漏输出，内部无上拉，外部接1M的上拉电阻，当PSW_1为1时，可输出LTLT1963AES8-3.3可输出3.3V电平，当PSW_1为0时，LTLT1963AES8-3.3可输出不是0V，而是1.4V，找不到原因。请帮分析下，电路图如下：
we are using this part for one of our RTC charging section Vbat is 12V when the LDO is charging the RTC capacitor during PowerUp and then a 75-ohm load Resistor is added Parallel to LDO o/p Manually. We are seeing a voltage dip across the LDO o/p it…
I try to use fixed 3.3V variant of LT3066. More precisely: LT3066EMSE-3.3 and somehow I get Vin to Vout.
My schematics is as follows:
Can you tell what is wrong with current schematics that I get 12V on OUT_1 and OUT_2 pins if I connect 12 V to IN_1…
After running the installer as admin and selecting "Install for everyone" I get the following error when attempting to start SigmaStudio as a non-administrative user from either the desktop or start menu shortcut:
Error 1001: Exception occurred…
Any idea about the scheduling for a bug fixed release of SigmaStudio ?
I could have sworn someone promised that in Sigma 3.3 the on-screen connection wires would stay put when importing a hirearchy board into a design. When creating a circuit, especially a complex one in which you must use "Insert Point" to keep routes clear…
用ADP7104-3.3做了一个稳压器，输入5V，输出3.3V。正常工作时候电流约为70mA。输出端并了三个电容：一个3528 10V 100uF的钽电容（靠近输出引脚）、一个0603 1uF 陶瓷电容、一个0603 1nF的陶瓷电容。
