LM4051AIM3X-1.2 from Texas Instruments, in a SOT-23. 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 | Cathode | output | Cathode regulated output terminal; provides 1.225V reference with ±1.2mV initial tolerance and ±5.2mV maximum over industrial temperature range -40°C to 85°C for operating current from 65µA to 12mA. |
| 2 | Anode | power_in | Anode ground/common reference terminal. |
| 3 | NC | unconnected | No connect terminal; must be left floating or connected to anode per section 8.1. |
