Hi Ella,
There is not a model for LM317HV. LM317HV has very similar performance to LM317 so the LM317 model can be used in its place.
TPS7A4001 is a newer version of TPS783.
These packages are both of the TO-220 group, but they are different TI packages…
Part Number: TPS7A02 Other Parts Discussed in Thread: TPS7A03 , TPS783 Hello,
I have a customer who is looking for ultra-low iq LDOs(under max 1uA),
4.3VBATT -> 3V output at 150mA max.
I offered the following devices which they liked:
TPS7A02
T…
Hi Gary,
Most of our newer LDO's do not have a minimum load requirement. So we don't have a specific parameter for the electrical characteristics section. We do have the following in the datasheet:
While the TPS783 was a good part when it…
Other Parts Discussed in Thread: TPS782 , TPS783 I have a question about TPS782 and TPS783.
TPS782 has "Active Pull-Down" in datasheet p.10 of internal circuit.
TPS783 does not have "Active Pull-Down" in datasheet p.10 of internal circuit.…
Hi Den,
For the LDO, please consider TPS783. The reason you may like this part over other devices is the low Ignd of the TPS783. You can find the parametric search optimized for Ignd here .
For the detector/supervisor, please consider LP3470. This has…
Part Number: TPS780 Other Parts Discussed in Thread: TPS783 , , TPS7A05 , TPS709 I'm looking for an LDO with ultra low Iq (~500nA like the TPS783) to go from 3.3V to 1.5V where output current isn't an issue. I found the TPS780 which says it has a fixed output…
Hi Anthony,
TPS782 and TPS783 are our lowest Iq LDOs. The difference between them is the active discharge circuitry on TPS782. Please refer to Figures 6 and 7 for an idea of how the ground current of TPS782 (and TPS783) drifts with temperature.
Very…
Hi Brian,
There's couple things you could try to help minimize overall quiescent current:
Increase pull-up resistance on I/O pins such as OTG, INT, STAT. These pins also have a pull-up resistor. On the EVM they are 10k, but you can probably increase…
