TPS79133-EP: LDO Regulator for LIPO (3.7 V) to 3.3V @ 100mA max w/enable

Frank Cardone43

Part Number: TPS79133-EP
Other Parts Discussed in Thread: TLV700, TLV755P, TLV733P

Greetings,

I'm looking for a LDO regulator that I can use to convert LIPO battery voltage (3.7V) to 3.3 volts @100mA max and an enable pin.

I would like to find a part with a SOT package or something that is easily soldered.

Thank you, Frank

Hello Frank,

Just to clarify before I provide you some recommendations, are you specifically looking for a -EP (enhanced plastics) power regulator? Also, since LIPO batteries can discharge to under 3.3V you may be interested in a buck-boost converter in order to get the full charge out of your battery (if that's important to you). Let me know and I'll then get back to you!

Thanks,

Kyle

Hi Kyle,

I do not need an "enhanced plastics" part.

I also don't need to regulate below 3.3V. I would like to regulate close to 3.3 but I don't have to go below.

Thank you for your help.

Frank, your post was directed to the High Reliability forum as you selected the -EP device.
I will see if I can re-direct back to the commercial group.
Regards,
Wade

Hi Frank,

We have several devices that will work for this application. I would recommend looking at the TLV755P, TLV700, and TLV733P. These are all available in SOT23-5 packages, so they should be fairly easy to work with.

Best Regards,
Mark
