LP2951CMMX-3.3 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; provides 3.3 V nominal output to the load. |
| 2 | SENSE | input | Output voltage sense input; connected to VOUT to provide feedback path for regulation. |
| 3 | SHUTDOWN | input | Logic-compatible shutdown input; disables device when driven low, quiescent current drops to 150 µA. |
| 4 | GND | power_in | Ground reference; device ground connection and substrate connection point. |
| 5 | ERROR | output | Error flag output; open-drain output that signals when output voltage falls below regulation set point. |
| 6 | VTAP | output | Internal resistor divider output; internal 1.235 V reference for feedback network. |
| 7 | FEEDBACK | input | Voltage feedback input; connected to external resistor divider to program output voltage from 1.24 V to 29 V. |
| 8 | IN | power_in | Input supply voltage; accepts 2.3 V to 30 V input with low dropout operation at typical 40 mV. |
