TL4051C12QDCKR from Texas Instruments, in a SC-70-5. 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 | ANODE | power_in | Anode terminal of the TL4051x12 fixed 1.225V shunt voltage reference; provides the return/ground-side connection for the cathode bias/load current. |
| 2 | NC | unconnected | Marked pin internally coupled to the anode through a parasitic Schottky diode; per the datasheet this pin must be connected to the anode (pin 1) or left floating, with connection to anode recommended in high-EMI or high-frequency switching-noise environments. |
| 3 | CATHODE | power_out | Cathode/regulated output terminal of the TL4051x12 fixed 1.225V shunt reference; sets the reference voltage (VZ = 1.225V typ) and operates over a cathode current range of 60µA (typ) minimum up to the 12mA recommended maximum. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
