Hi Antony, I am doing the same thing as Micheal and I have the same issue with heating.
Where exactly could I put a diode across? (i'm assuming from OUT -->| GND of the LM3480). Does this work? Is there any side effects to the performance of the…
Part Number: LM3480 Other Parts Discussed in Thread: TPS709
I'm trying to reduce the power consumption of an existing design without modifying the PCB.
Is there a similar part with lower current draw? Normal Vout draw is 8mA, but in sleep mode, only…
Part Number: LM3480 Hi Everyone, Im new to this forum so sorry if this is a repeated or obviously question.
I have designed a circuit with this regulator intended to take input from a 9V battery and regulate it to 5V for an attiny microcontroller. I first…

Other Parts Discussed in Thread: LM3480 Hey team,
I am looking at this LDO LM3480 on ti.com.
Is this stable with both ceramic and electrolytic capacitor at the input and output terminals?
I tried to look for this information in data sheet but could not…

Hi Amit,
I looked closer at your schematic and I see CHRG_OK and the 3.3V pullup is implemented very similar to our EVM. I don't see any issues. Have you confirmed your 3.3V rail is at 3.3V ( at LM3480 Vo pin)?
Thanks,
Khalid
I too 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 8 years, never had this kind of issue…
Hi at all.
I have another question regarding the LM3480 - and found no better place to write into! So, here's my question:
Is the LM3480 protected against reverse polarity of supply voltage? I found no information in the datasheet.
Thanks in advance…
