REF192GRUZ-REEL7 from Analog Devices, in a TSSOP-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 | TP | unconnected | Factory Zener-zap test pin reserved for in-package trimming; the user should leave it unconnected. |
| 2 | VS | power_in | Supply input, which must be at least 100 mV above the output voltage for stable regulation, with supply current below 45 µA. |
| 3 | SLEEP | input | Sleep-mode control that turns the output off and reduces supply current to less than 15 µA when a low TTL or CMOS level is applied. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TP | unconnected | Factory Zener-zap test pin reserved for in-package trimming; the user should leave it unconnected. |
| 6 | OUTPUT | output | Precision voltage reference output, rated for up to 30 mA with short-circuit protection. |
| 7 | NC | unconnected | No connect; leave unconnected. |
| 8 | NC | unconnected | No connect; leave unconnected. |
