L78M24ABDT-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

L78M24ABDT-TR from STMicroelectronics, in a TO-252-2(DPAK). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 INPUT power_in Unregulated DC input voltage V_I. Absolute maximum 40 V for the 24 V output variant. A 0.33 uF input decoupling capacitor is recommended close to the pin.
2 GROUND power_in Common ground reference for input and output. On the DPAK package the GND pin is electrically connected to the exposed thermal tab.
3 OUTPUT power_out Regulated +24 V DC output, up to 0.5 A with adequate heat sinking. A 0.1 uF output capacitor is recommended for transient response.
