CM5102-SOPTA from CIMO, in a SOP-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 | Used for internal test; leave floating or connect to GND. |
| 2 | VIN | power_in | Supply input, 4V~36V. |
| 3 | TEMP | output | Temperature sensing output, about 355mV at 25℃ with 1.3mV/℃ slope; abs max 36V. |
| 4 | GND | power_in | Ground. |
| 5 | TRIM | passive | Output voltage trim pin; an external resistor network can be connected to trim the output voltage; abs max 36V. |
| 6 | VOUT | output | 2.5V/3.0V reference voltage output, up to 10mA source/sink; abs max 36V. |
| 7 | CAP | passive | Connect a compensation capacitor between this pin and VOUT when the VOUT load capacitor exceeds 0.1μF to keep the system stable. |
| 8 | SEL | input | Output voltage select: tie to GND for 3.0V output, leave floating for 2.5V output. |
