NCV78M05BDTRKG

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

NCV78M05BDTRKG from onsemi, 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 positive input voltage. Maximum rating 35 Vdc (40 V for 20-24 V options). Recommended operating input at least ~2 V above V_O for regulation (dropout typ 2.0 V).
2 Ground power_in Common ground reference for input and output. The DPAK heatsink tab (shown as terminal 4 in the case outline) is internally connected to Pin 2 (Ground).
3 Output power_out Regulated +5.0 V output (4.8-5.2 V at T_J = 25 C for the B grade). Delivers up to 500 mA continuous with adequate heatsinking; short-circuit current limit ~350 mA typ, peak output current ~700 mA.
4 Heatsink/Tab passive DPAK-3 exposed heatsink tab (terminal 4 in the case outline drawing). Internally connected to Pin 2 (Ground). Solder to a copper pour for thermal dissipation.

Provenance

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

  • Datasheet: onsemi datasheet (15 pp, sha256 2339bbc0a38dcd3b, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
