LM2937ET-5.0

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

LM2937ET-5.0 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 datasheet gives VIN as VOUT + 1 V minimum to 26 V maximum in recommended operation, with a 60 V transient limit (t ≤ 100 ms).
2 GND power_in Ground, and also the thermal tab connection; the tab is internally connected to this pin and should be tied to GND or left floating, never to any other potential.
3 OUTPUT power_out Regulated voltage output that requires an output capacitor to maintain stability; the datasheet's Detailed Design Procedure section gives the capacitor details.
