Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4
LM2937IMPX-10 from Texas Instruments, in a SOT-223-4. 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 | INPUT | input | Unregulated voltage input; VIN must stay between VOUT + 1 V and 26 V continuous, with 60 V transients allowed for up to 100 ms. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | OUTPUT | output | Regulated voltage output that requires an output capacitor for stability, and the device is stable for capacitor ESR below 3 Ω. |
| 4 | TAB | power_in | Thermal and ground tab internally connected to pin 2 (GND); connect it to GND or leave it floating, and do not connect it to any potential other than GND. |
