LM7705MMX from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CF+ | passive | Positive terminal of external flying capacitor (CFLY) for switched-capacitor charge pump inverter. |
| 2 | VSS | power_in | Power ground reference. |
| 3 | SD | input | Shutdown control input: logic LOW enables device, logic HIGH disables device and reduces shutdown supply current to 20nA. |
| 4 | VDD | power_in | Positive supply voltage input, operating range 3V to 5.25V per recommended operating conditions. |
| 5 | VSS | power_in | Power ground reference. |
| 6 | VOUT | power_out | Regulated negative output voltage of −0.232V typical with ±5% tolerance and 4mVPP maximum output ripple. |
| 7 | CRES | passive | External reserve capacitor connection for output voltage filtering and ripple reduction. |
| 8 | CF- | passive | Negative terminal of external flying capacitor (CFLY) for switched-capacitor charge pump inverter. |
