ZJR1000-9AUABR

ZJW · Voltage Reference · MSOP-8

ZJR1000-9AUABR from ZJW, in a MSOP-8. 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 DNC unconnected Do Not Connect. Pin has an actual internal connection reserved for factory testing; do not connect anything to it or the device may not function properly.
2 VIN power_in Input supply voltage. Operating range is VOUT+0.3 V to 15 V (2.5 V min for ZJR1000-1/-2 variants). Recommended to bypass with 0.1 µF to 10 µF ceramic capacitor close to the pin.
3 SHDN input Active-low shutdown input. Pulling low powers the device down to 16 µA typical. VIL ≤ 0.8 V, VIH ≥ 2 V (up to VIN). CMOS/TTL compatible with an internal pull-up; recommended to tie high externally for best performance during normal operation.
4 GND power_in Ground reference pin = 0 V. Connect to system ground plane; keep the return path low-impedance.
5 TRIM input Trim terminal for adjusting the output voltage over a ±0.5% range without affecting temperature coefficient. Typically connected to a low-tempco resistor divider network (with wiper going to TRIM) between VOUT and GND. Leave open if adjustment is not needed.
6 VOUT power_out Precision voltage reference output. For ZJR1000-9 the nominal output is 2.5 V with ±0.05% initial accuracy. Requires a 0.1 µF to 10 µF output decoupling capacitor with ESR ≤ 1.5 Ω for stability. Short-circuit current is typically 20 mA.
7 NIC unconnected No Internal Connection. Pin has no internal circuitry; may be left floating or tied to GND.
8 DNC unconnected Do Not Connect. Reserved for factory testing purposes. Do not connect anything or device may malfunction.
