LM4041DIM7X-ADJ 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 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net. |
| 2 | A | passive | Anode (正极) of the shunt reference. Normally connected to ground (system return); forms the low side of the internal 1.225 V bandgap shunt element. |
| 3 | K | passive | Cathode (负极) of the shunt reference. Sinks the shunt current supplied through an external series resistor from Vsupply; the regulated output voltage (1.24 V to 10 V, set by the FB divider) appears here relative to the anode. IR range 60 µA to 12 mA. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net. |
| 5 | FB | input | Feedback input for the adjustable reference. An external resistor divider from cathode (K) to anode (A), with its tap connected to FB, programs the cathode-anode voltage to VR = 1.240 V × (1 + R1/R2). High-impedance node - keep divider currents ≫ FB input bias current (~100 nA typ) for best accuracy. HBM ESD rating on FB is 1 kV (vs 2 kV on other pins). |
