LM9036QMX-3.3 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 | VOUT | power_out | Regulated 3.3V output (±5% over line, load and temperature, up to 50mA) that needs a 22µF to 33µF output capacitor with 0.3Ω to 8Ω ESR for stability. |
| 2 | GND | power_in | Ground pin, internally connected to the other GND pins, with ground pin current of 25µA maximum at 0.1mA load. |
| 3 | GND | power_in | Ground pin, internally connected to the other GND pins, which also serves as the heat-sinking path for the package. |
| 4 | N/C | unconnected | No internal connection. |
| 5 | N/C | unconnected | No internal connection. |
| 6 | GND | power_in | Ground pin, internally connected to the other GND pins, which also serves as the heat-sinking path for the package. |
| 7 | GND | power_in | Ground pin, internally connected to the other GND pins, which also serves as the heat-sinking path for the package. |
| 8 | VIN | power_in | Unregulated input voltage, operating up to 40V maximum, survival +55V/−45V, with a 100nF capacitor needed if more than 2 inches from the supply filter capacitor. |
