ZJR1004-2BUABT

ZJW · Voltage Reference · MSOP-8

ZJR1004-2BUABT 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 pin, 2.8 V (ZJR1004-2) or VOUT+0.3 V (other versions) up 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, and tying it high externally is recommended.
4 GND power_in Ground pin = 0 V.
5 NIC unconnected No internal connection.
6 VOUT power_out Output voltage; requires a 0.1 µF to 10 µF load capacitor to GND and can drive up to 20 mA.
7 NIC unconnected No internal connection.
8 NIC unconnected No internal connection.
