L78M24ACDT-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK

L78M24ACDT-TR from STMicroelectronics, in a DPAK. 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 Regulator input; DC input voltage must not exceed 40 V for the 24 V version, with 27 to 38 V specified for the L78M24 electrical characteristics and a 0.33 µF bypass capacitor recommended close to the pin.
2 GND power_in Ground reference, shown in Figure 2 as the DPAK mounting tab with the middle lead cut short.
3 OUTPUT power_out Regulated 24 V output (23.5 to 24.5 V at 25 °C for the A version) with output current up to 0.5 A and internal current limiting.

  • Symbol: L78M24ACDT-TR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: l78m24acdt-tr-etched.step / l78m24acdt-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l78m24acdt-tr.step / l78m24acdt-tr.glb are the bare package body.
