  • LM3480 reverse output voltage overheating

    Other Parts Discussed in Thread: LM3480 , TPS709 I have designed an LM3480 into a battery powered microcontroller board. The microcontroller is currently being programmed in-circuit, which means +5V is applied to the output of the LM3480 with no voltage…

  • LM3480 Failing at 24 VDC input

    Other Parts Discussed in Thread: LM3480 I am having a large percentage of failures of this regulator testing the units with no load. Output capacitor is 10 uF, input is 4.7 uF in parallel with 0.1 uF. Supply is 24 VDC. Board is a mature product for over…

  • LM3480 self destructs without load

    Other Parts Discussed in Thread: LM3480 Hello, I'm using LM3480 to drop voltage from 24V down to 5V at very low current (<2mA). It's the standard application with 0.1uF for Cin and Cout. There is also a ferrite bead before the Cin and another ferrite…

  • LM3480 Operation at extreme low temp

    Other Parts Discussed in Thread: LP2951 , LM3480 We are looking to reuse the LM3480 device in a new application whose operational temp range could be as low as -55C. The datasheet reports that the operating temp range is -40C. What will happen to the device…
