LM7705MM from Texas Instruments, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CF+ | passive | Flying capacitor positive connection; external 5µF capacitor connects between CF+ and CF- with low ESR and short traces per layout guidelines. |
| 2 | VSS | power_in | Power ground; provides return path for internal circuits and power supply. |
| 3 | SD | input | Shutdown control input; logical low enables −0.23V output generation, logical high disables device and switches output to ground. |
| 4 | VDD | power_in | Positive power supply input; accepts 3.0V to 5.25V supply voltage with adjacent decouple capacitor recommended. |
| 5 | VSS | power_in | Power ground; provides return path for internal circuits and power supply. |
| 6 | VOUT | output | Regulated negative output voltage; generates fixed −0.232V nominal with external 22µF output capacitor recommended to minimize ripple. |
| 7 | CRES | passive | Reserve capacitor connection; external 22µF capacitor connects between CRES and VSS with low ESR and short traces per layout guidelines. |
| 8 | CF- | passive | Flying capacitor negative connection; external 5µF capacitor connects between CF+ and CF- with low ESR and short traces per layout guidelines. |
