LM2937ET-12

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

LM2937ET-12 from Texas Instruments, in a TO-220. 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 power_in Unregulated voltage input; the input must be at least VOUT + 1 V and no more than 26 V continuous, with 60 V transient protection for up to 100 ms.
2 GND power_in Ground pin, internally connected to the TAB, which must be connected to GND or left floating and must not be connected to any other potential.
3 OUTPUT power_out Regulated voltage output that requires an output capacitor to maintain stability; the device is stable for output capacitor ESR below 3 Ω.
