LMC7660IM from Texas Instruments, in a SOIC-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 | N/C | unconnected | No connection internally on the pin configuration. |
| 2 | CAP+ | passive | Positive terminal of the pump capacitor Cp, connected to switches S1 and S2. |
| 3 | GND | power_in | Ground, connected to switch S2; the datasheet warns inputs must not go below ground to avoid latchup. |
| 4 | CAP- | passive | Negative terminal of the pump capacitor Cp, connected to switches S3 and S4. |
| 5 | VOUT | power_out | Negative output voltage (-V+) held on reservoir capacitor Cr; do not short circuit the output to V+. |
| 6 | LV | input | Low-voltage pin: short to ground only for V+ <= 3.5V, and leave open for V+ >= 3.5V to prevent damage; input range -0.3V to V+ + 0.3V for V+ < 5.5V, current into pin 20 uA max. |
| 7 | OSC | input | Oscillator pin for an external slow-down capacitor Cosc or external clock overdrive, with the pumping frequency half the external clock; input range -0.3V to V+ + 0.3V for V+ < 5.5V. |
| 8 | V+ | power_in | Positive supply input, 1.5V to 10V operating range, 10.5V absolute maximum. |
