ZJR1004-0BUAER from ZJW, in a MSOP-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 | NIC | unconnected | No internal connection. |
| 2 | VIN | power_in | Input voltage supply, 2.8 V (or VOUT+0.3 V) to 40 V. |
| 3 | EN | input | Active-low enable input that powers the device down to 9 µA; if left open an internal pull-up resistor enables normal operation, but tying it high externally is recommended. |
| 4 | GND | power_in | Ground pin, 0 V. |
| 5 | NIC | unconnected | No internal connection. |
| 6 | VOUT | output | Output voltage reference (10 V for the ZJR1004-0 variant), requiring a 0.1 µF to 10 µF load capacitor to GND. |
| 7 | NIC | unconnected | No internal connection. |
| 8 | NIC | unconnected | No internal connection. |
