GM7400BRZ-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 | Supply input, operating range 3.3V to 40V with an absolute maximum of +45V. |
| 3 | TEMP | output | Temperature monitoring output, typically 657 mV with a 2.2 mV/°C temperature coefficient. |
| 4 | GND | power_in | Ground. |
| 5 | TRIM | input | Output voltage trim input, giving about ±3% typical (±6% max) adjustment range with a 10 kΩ potentiometer. |
| 6 | VOUT | output | Reference voltage output (2.5V for this part) that sources/sinks ±10mA, with 30mA typical short-circuit current and a recommended 0.1µF ceramic output capacitor. |
| 7 | NC | unconnected | No internal connection; leave floating in the application. |
| 8 | NC | unconnected | No internal connection; leave floating in the application. |
