LP2951CN from Texas Instruments, in a PDIP-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 | OUT | power_out | Regulated output voltage; in dual-supply systems where the output sees loads returned to a negative supply, the output should be diode-clamped to ground. |
| 2 | SENSE | input | Output voltage sense input, which the 8-pin test conditions tie to OUT; the datasheet gives an absolute input voltage range of -0.3 V to 30 V for the SHUTDOWN, ERROR and IN class of pins, and ESD rating of ±1500 V for this pin. |
| 3 | SHUTDOWN | input | Logic-compatible shutdown input that disables the device; the electrical characteristics are specified with VSHUTDOWN ≤ 0.8 V and the absolute maximum input voltage is -0.3 V to 30 V. |
| 4 | GROUND | power_in | Ground reference pin for the regulator. |
| 5 | ERROR | output | Error flag output that warns of low output voltage (dropout), with an absolute maximum voltage of -0.3 V to 30 V. |
| 6 | VTAP | output | Internal resistor divider tap, which the 8-pin test conditions tie to FEEDBACK. |
| 7 | FEEDBACK | input | Voltage feedback input with an absolute input voltage range of -1.5 V to 30 V; the 8-pin test conditions tie it to VTAP. |
| 8 | IN | power_in | Input supply voltage, specified from 2.3 V to 30 V with an absolute maximum of 30 V. |
