Overview

The LM7705MM is a charge Pump made by Texas Instruments in a MSOP-8 package with 8 pins. -232mV -40℃~+125℃ 230mΩ 26mA 3V~5.25V 78uA 92kHz 98% Inverted Not supported MSOP-8 Charge Pumps ROHS.

PCBKit's library has its KiCad symbol (Regulator_SwitchedCapacitor:LM7705, from KiCad's library) and its footprint (Package_SO:MSOP-8_3x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. 309 are in stock at JLCPCB (part C129980). 3 open-source boards in 3 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the LM7705MM?

Yes. The symbol is Regulator_SwitchedCapacitor:LM7705 and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM7705MM?

MSOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM7705MM datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM7705MM?

JLCPCB lists it as part C129980, with 309 in stock; the sellers' links on this page open their listings.

What can replace the LM7705MM?

Parts like it in the library: the LM7705MME by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM7705MM?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
