TL751L12CDR from Texas Instruments, in a SOIC-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 | OUTPUT | power_out | Regulated 12-V output (11.52 V to 12.48 V at 25°C) delivering 0 to 150 mA, requiring a 10-μF output capacitor with ESR below 0.4 Ω. |
| 2 | COMMON | power_in | Ground/common reference pin, connected internally with the other COMMON pins (3, 6, 7). |
| 3 | COMMON | power_in | Ground/common reference pin, connected internally with the other COMMON pins (2, 6, 7). |
| 4 | NC | unconnected | No internal connection. |
| 5 | ENABLE | input | Active-low TTL/CMOS-compatible enable input; high level (2 V to 15 V) disables the output into high impedance, low level is -0.3 V to 0.8 V at 25°C. |
| 6 | COMMON | power_in | Ground/common reference pin, connected internally with the other COMMON pins (2, 3, 7). |
| 7 | COMMON | power_in | Ground/common reference pin, connected internally with the other COMMON pins (2, 3, 6). |
| 8 | INPUT | power_in | Regulator input supply, 13 V to 26 V recommended for the 12-V version, with 60-V transient and -15 V continuous reverse rating tolerance as stated (26 V continuous max). |
