LP2951ACMM from Texas Instruments, in a VSSOP-8-0.65mm. 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 | OUT | output | Regulated output voltage of the LP2951-N; the electrical characteristics are specified with CL = 1 µF for 5-V versions and 2.2 µF for 3-V and 3.3-V versions. |
| 2 | SENSE | input | Output voltage sense input, which the datasheet specifies tied to OUT in the 8-pin test conditions. |
| 3 | SHUTDOWN | input | Logic-compatible shutdown input that enables or disables the regulator, with the 8-pin test conditions specifying VSHUTDOWN ≤ 0.8 V. |
| 4 | GND | power_in | Ground reference pin for the regulator; the datasheet recommends a wide ground return connection close to the input and output capacitors. |
| 5 | ERROR | output | Error flag output that warns of a low output voltage (such as falling input battery voltage) and may be used for power-on reset. |
| 6 | VTAP | output | Internal resistor divider tap, which the 8-pin test conditions specify tied to FEEDBACK. |
| 7 | FEEDBACK | input | Voltage feedback input for programming the output from 1.24 V to 29 V; absolute maximum input voltage range is -1.5 V to 30 V. |
| 8 | IN | power_in | Input supply voltage, with a recommended range of 2.3 V to 30 V and an absolute maximum of 30 V. |
