GM7401ARZ-3.3-R7

GONGMOSEMI · Voltage Reference · SO-8

GM7401ARZ-3.3-R7 from GONGMOSEMI, in a SO-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 NC unconnected No internal connection; float in the application.
2 VIN power_in Power supply input; electrical characteristics are specified with VIN = MAX((VOUT + 1 V), 3.5 V), and the absolute maximum input voltage is 45 V.
3 TEMP output Temperature monitor pin providing an unbuffered PTAT voltage of 657 mV typical with a 2.2 mV/°C temperature sensitivity.
4 GND power_in Ground reference for the device.
5 TRIM passive Output voltage trim pin; with a 10 kΩ potentiometer the output adjustment range is listed as ±3 ±6 %.
6 VOUT power_out Voltage reference output, rated for +/-10 mA output drive (at low output impedance) with internal short-circuit current protection.
7 NC unconnected No internal connection; float in the application.
8 NC unconnected No internal connection; float in the application.
