LM7805AL-TA3-T

UTC(Unisonic Tech) · Linear Voltage Regulators (LDO) · TO-220

LM7805AL-TA3-T from UTC(Unisonic Tech), 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 I power_in Input pin: the datasheet gives an absolute maximum input voltage of 35 V for VOUT=5 to 18 V (40 V for VOUT=24 V).
2 G power_in Ground (GND) pin, the common reference for the regulator; quiescent current IQ is specified at 8.0 mA maximum with TJ=25°C and IOUT≤1.0 A.
3 O power_out Regulated output pin: the fixed output is 5.0 V (typ) for the LM7805A, with output current up to 1.5 A.

CAD (KiCad official)

  • Symbol: LM7805AL-TA3-T
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: lm7805al-ta3-t-etched.step / lm7805al-ta3-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm7805al-ta3-t.step / lm7805al-ta3-t.glb are the bare package body.
