LP2997MRX from Texas Instruments, in a ESOP-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 connection. |
| 2 | SD | input | Active low shutdown pin for Suspend to RAM functionality; when pulled low, VTT tri-states while VREF remains active. |
| 3 | VSENSE | input | Feedback pin for remote load regulation of VTT; connect to termination bus at regulation point, typically middle of bus for optimal distribution. |
| 4 | VREF | power_in | Buffered output of internal reference voltage equal to VDDQ/2; provides reference voltage for chipset and memory. |
| 5 | VDDQ | power_in | Input for internal 50kΩ resistor divider generating reference voltage; connect directly to 1.8V rail at DIMM for accurate tracking without voltage drop. |
| 6 | AVIN | power_in | Analog supply input for internal control circuitry; operating range 2.2V to 5.5V (typical 2.5V). |
| 7 | PVIN | power_in | Power supply input for output stage; connect to 1.8V or 2.5V rail; AVIN must be greater than or equal to PVIN. |
| 8 | VTT | output | Regulated output voltage equal to VDDQ/2; capable of sinking and sourcing ±0.5A continuous current with transient peaks up to 900mA. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
