# AD586LRZ-REEL7

**Analog Devices** · Voltage References · SOIC-8

AD586LRZ-REEL7 from Analog Devices, 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 | TP1 | unconnected | Factory trim pad for internal test; make no connections to this pin except a dummy PCB pad. |
| 2 | VIN | power_in | Supply input; the datasheet gives a VIN-to-ground absolute maximum of 36 V and a specified line-regulation range of 10.8 V < VIN < 36 V. |
| 3 | TP1 | unconnected | Factory trim pad for internal test; make no connections to this pin except a dummy PCB pad. |
| 4 | GND | power_in | Ground reference; the output is referenced to this pin, which is grounded for normal +5 V operation. |
| 5 | TRIM | input | Optional external fine-trim connection that can offset the output by as much as 300 mV using the trim circuit in Figure 6. |
| 6 | VOUT | power_out | 5 V reference output that can source or sink 10 mA and is safe for indefinite short to ground or VIN. |
| 7 | TP1 | unconnected | Factory trim pad for internal test; make no connections to this pin except a dummy PCB pad. |
| 8 | NOISE REDUCTION | passive | Optional noise-reduction filter pin; an external 1 µF capacitor to ground reduces Zener noise. |
