GM7400ARZ-2.5-R7

GONGMOSEMI · Voltage Reference · SO-8

GM7400ARZ-2.5-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; leave floating in the application.
2 VIN power_in Power supply input; the features list gives a 3.5 V to 40 V supply range and the absolute maximum input voltage is 45 V.
3 TEMP output Temperature monitoring pin that outputs an unbuffered PTAT voltage of 657 mV typical with a temperature sensitivity of 2.2 mV/°C per the electrical characteristics table.
4 GND power_in Ground reference for the device.
5 TRIM passive Output voltage trim pin that adjusts VOUT by ±3% to ±6% with a 10 kΩ potentiometer, per the electrical characteristics table.
6 VOUT power_out Reference voltage output, rated for ±10 mA output current with a 30 mA short-circuit current limit.
7 NC unconnected No internal connection; leave floating in the application.
8 NC unconnected No internal connection; leave floating in the application.
