Other Parts Discussed in Thread: LP38690 Hello,
I am using this particular IC in one of my project where I came across a point wherein it stated the unit of dropout voltage to be "mA" rather than being "V". please refer page no. 5 of LP38690 Linear regulator…
Hey Sonali,
Your circuit looks correct.
However, because the datasheet specifies polarized capacitors, it makes me think that this part may need a minimum ESR to be stable.
There is no mention of it in the datasheet but it may be a safe choice to include…
Any feedback yet?
Also, I see that for the lp38690, there is a spec for minimum load current of 100 uA.
Our minimum load current will be well below 100uA. Will this par work or is there another that is more suited for this?
1. Could you capture the waveform:
- at the output of the TPS63031 before the bridge?
- At the end of the cable for different length? for ex. 0.2, 10 and 20meters
2. What is sm?
3. What measurement is the indicator providing? (voltage, current...etc…

Other Parts Discussed in Thread: BQ25100 , LP38690 , TPS61253 Hi, All!
I attach a schematic file. 3343.POWER.pdf
That is used TPS61253, LP38690 and BQ25100 for wearable device.
Please, Reviwe & comment , ASAP.

Based on the criteria given, I don't see anything close available in TO-220-5. Best fit would probably be the TPS76850 - but it's only available only in either 8-pin SOIC, or 20-pin HTSSOP. If I remove the 'Power Good' requirement, the LP38690,…
