ZJW · Voltage Reference · SOT-23-6
ZJR1001-3BUTBR from ZJW, in a SOT-23-6. 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 | FILTER | input | Filter input; connect a 0.1 µF capacitor from FILTER to ground for high-frequency bypass, or leave it unconnected if not used. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | ENABLE | input | Enable input: drive high to enable the device and low to put it in shutdown (3 µA typ. supply current); logic high minimum 2 V, logic low maximum 0.8 V, and it has a weak internal pull-up if left unconnected. |
| 4 | IN | power_in | Supply voltage input; the supply must be VOUT + 0.3 V to 5.5 V. |
| 5 | OUTS | power_out | Voltage reference sense output, to be kept as close to the load as possible and shorted to OUTF there. |
| 6 | OUTF | power_out | Voltage reference force output; short to OUTS as close as possible to the load and bypass with 0.1 µF to 10 µF to GND. |
