LP2951ACMX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Regulated output voltage, fixed 3V/3.3V/5V or programmable 1.24V to 29V with 100mA ensured output current. |
| 2 | SENSE | input | Output voltage sense input for internal feedback divider; tie to OUT for fixed voltage operation. |
| 3 | SHUTDOWN | input | Logic-compatible disable input; regulator enables below 0.7V and disables above 1.3V. |
| 4 | GND | power_in | Ground reference terminal, common connection point for return paths. |
| 5 | ERROR | output | Open-collector error flag output; pulls low when output drops 75-95mV below 1.235V reference threshold. |
| 6 | VTAP | output | Internal 1.235V reference voltage divider tap; tie to FEEDBACK pin for fixed voltage versions. |
| 7 | FEEDBACK | input | Voltage feedback input for programmable output regulation; -20nA typical bias current. |
| 8 | IN | power_in | Positive power supply input voltage, 2.3V to 30V absolute maximum range. |
