LP2996MX 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 | GND | power_in | Ground reference. |
| 2 | SD | input | Active-low shutdown input that tri-states VTT while maintaining VREF active and reducing quiescent current; has internal pullup. |
| 3 | VSENSE | input | Feedback input for remote load regulation of VTT; connect to middle of termination bus or to VTT output if remote regulation not used. |
| 4 | VREF | power_in | Buffered output of VDDQ/2 reference for Northbridge and memory; remains active during shutdown and thermal shutdown. |
| 5 | VDDQ | power_in | Input for internal reference generating VTT = VDDQ/2 via two 50-kΩ internal resistors; optimal connection is directly to 2.5-V rail at DIMM. |
| 6 | AVIN | power_in | Power supply input for internal control circuitry; must be ≥ PVIN and typically connected to 2.5-V with PVIN for SSTL-2 applications. |
| 7 | PVIN | power_in | Power input for output stage; must be ≤ AVIN; higher values increase maximum continuous output current up to 1.5 A but increase power dissipation. |
| 8 | VTT | tri_state | Regulated output for termination resistors capable of sourcing and sinking up to ±3 A peak current; tri-states during shutdown or thermal shutdown. |
