LM4040CIM3-5.0+T from Analog Devices Inc Maxim Integrated, in a SOT-23-3. 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 | + | passive | Positive (cathode) terminal of the shunt reference. Tie through a source resistor RS to VS so that shunt current stays between 60µA (IRMIN) and 15mA; the pin regulates to VR = 5.000V (±0.5% initial for the C grade) with respect to pin 2. Absolute-maximum reverse current is 20mA; forward current (pin 2 to pin 1) is limited to 10mA. |
| 2 | - | passive | Negative (anode) terminal of the shunt reference; the low-side return for the 5.000V reverse-breakdown voltage. Typically connected to the circuit ground/common reference node. |
| 3 | N.C. | unconnected | No internal connection. Leave floating or tie to pin 2 (the '-' terminal); do not connect to any other net. |
