LM2937IMPX-10

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.
