ADR280ARTZ-REEL7 from Analog Devices, 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 | V+ | power_in | Positive supply input pin. Operating range 2.4 V to 5.5 V (absolute max 6 V). Should be decoupled with a 0.1 µF ceramic capacitor mounted close to the pin. |
| 2 | VOUT | output | 1.2 V precision band gap voltage reference output (1.195 V min, 1.205 V max at 25°C). Drives up to 100 µA load; requires a 0.1 µF ceramic output capacitor for optimum stability (COUT typ 1 µF nominal). |
| 3 | V- | power_in | Negative supply / ground reference pin. Normally tied to system ground; can be elevated above ground to establish a floating 1.2 V differential reference above V- (see Figure 13). |
