LM237KCSE3

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

LM237KCSE3 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 ADJUSTMENT input Adjustment pin for the output voltage; connect two external resistors to set VO, with the reference voltage typically 1.25 V higher than VO.
2 INPUT input Input voltage (VI); for best performance the input-to-output differential must be between -2.5 V and -37 V, with an absolute maximum VI - VO of -40 V.
3 OUTPUT output Output voltage (VO) supplying up to 1.5 A; a 1-µF solid tantalum or 10-µF aluminum electrolytic capacitor is required on this pin for stability.

CAD (KiCad official)

  • Symbol: LM237KCSE3
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: lm237kcse3-etched.step / lm237kcse3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm237kcse3.step / lm237kcse3.glb are the bare package body.
