LM337MDTR

XBLW · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2L

LM337MDTR from XBLW, in a TO-252-2L. 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 ADJ input Adjustment pin for the output voltage; connect two external resistors to adjust the output voltage.
2 VIN power_in Input voltage pin (also connected to the package tab); the input-output differential is limited to 40 V max.
3 VOUT power_out Regulated negative output voltage pin, adjustable from -1.25 V to -37 V at 1.5 A or more.

CAD (KiCad official)

  • Symbol: LM337MDTR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2L (KiCad packages3D, STEP)
  • 3D model files: lm337mdtr-etched.step / lm337mdtr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm337mdtr.step / lm337mdtr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: XBLW datasheet (14 pp, sha256 f9dff5cc4923ee49, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
