Product details
Overview
MC7806ACTG from onsemi is a fixed-output +6.0 V, 1.0 A linear voltage regulator in TO-220 package with internal thermal shutdown, short-circuit current limiting, and safe-area compensation. It delivers stable DC power for local regulation in industrial control, automotive subsystems, and embedded power supplies where input ripple and load transients are present.
For engineers reviewing the MC7806ACTG datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, thermal performance data, real-world stability guidance, and validated alternative parts for design-in and supply continuity planning.
Technical Context
The MC7806ACTG employs a monolithic bipolar pass transistor with built-in safe-area compensation to maintain SOA integrity under high VIN–VOUT differentials. Its internal current limit activates at 0.2 A (typical) during output short circuits, and thermal shutdown engages at +150°C junction temperature.
It requires a minimum input-to-output differential of 2.0 V (at IO = 1.0 A, TJ = 25°C) and achieves 62 dB ripple rejection at 120 Hz with 11.5–23 VIN. Output voltage tolerance is ±4% over temperature and load (5 mA ≤ IO ≤ 1.0 A, PD ≤ 15 W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +6.0 V nominal, ±4% over full operating range - ensures compatibility with 5.76–6.24 V logic and analog rails |
| Output Current | 1.0 A continuous - supports mid-power microcontrollers, sensors, and interface ICs without external boost |
| Dropout Voltage | 2.0 V at 1.0 A - mandates ≥8.0 V input for reliable 6.0 V output under full load |
| Ripple Rejection | 62 dB at 120 Hz - suppresses AC line-derived noise in unregulated DC supplies |
| Quiescent Current | 3.3 mA typical - minimizes no-load power loss in battery-backed or standby systems |
| Thermal Shutdown | Activates at +150°C junction temperature - prevents permanent damage during sustained overload |
| Short-Circuit Limit | 0.2 A typical - limits fault current to protect PCB traces and upstream components |
Pinout & Package
MC7806ACTG uses the standard TO-220 (Case 221AB) package with metal tab electrically connected to Pin 2 (Ground). The heatsink surface must be isolated or grounded per system requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Input | Unregulated DC input; requires ≥8.0 V for 6.0 V output at 1.0 A; bypass capacitor (≥0.33 µF) recommended |
| Pin 2 | Ground | Common reference for input and output; metal tab connection enables mechanical heatsinking and electrical grounding |
| Pin 3 | Output | Regulated +6.0 V output; stable without output capacitor but benefits from 0.1–1.0 µF for transient response |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | Self-contained regulation with integrated pass element, error amplifier, and protection circuitry - reduces BOM count and layout complexity |
| Internal thermal overload protection | Automatic shutdown at +150°C junction temperature - eliminates need for external thermal sensors or shutdown logic |
| Internal short-circuit current limiting | Clamps output current to ~0.2 A during hard shorts - prevents catastrophic failure and enables safe auto-recovery |
| Safe-area compensated output transistor | Reduces short-circuit current as VCE increases - maintains SOA compliance across wide input/output differentials |
| Pb-free and RoHS-compliant | Meets environmental compliance standards without derating or process changes - suitable for global industrial and automotive shipments |
Applications
| Industrial PLC I/O Module | Automotive Body Control Unit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC7806CD2TG | Same +6.0 V output and 1.0 A rating, but in DPAK-3 (TO-252) surface-mount package; RJA = 65°C/W vs. 92°C/W for TO-220 | Designed for automated SMT assembly and space-constrained PCBs; lacks through-hole mounting and direct heatsink interface | Select when board area is limited and thermal management uses PCB copper pour instead of external heatsink |
| NCV7806ABDTKG | Automotive-grade variant with AEC-Q100 qualification, wider −40°C to +150°C operating range, and tighter ±2% output tolerance | Required for safety-critical automotive body electronics; includes PPAP documentation and enhanced ESD robustness (HBM 2000 V) | Select for new automotive designs requiring qualification evidence and extended temperature performance |
Compared with MC7806ACTG, MC7806CD2TG offers superior thermal resistance in compact SMT form, while NCV7806ABDTKG adds automotive qualification and tighter tolerance at higher cost-enabling selection based on assembly method and compliance needs rather than functional substitution.

FAQ
What is the maximum input voltage rating for MC7806ACTG?
The MC7806ACTG has an absolute maximum input voltage of 35 V DC. Operation above this level risks permanent damage. For reliable 6.0 V output at 1.0 A, the input must remain ≥8.0 V (2.0 V dropout), and typical design practice limits input to ≤25 V to manage power dissipation and thermal stress within the TO-220 package.
Does MC7806ACTG require an input bypass capacitor?
Yes - an input bypass capacitor of ≥0.33 µF (tantalum, ceramic, or film) is recommended for MC7806ACTG when connected via >2 inch traces to the power source. This stabilizes regulation under fast load transients and suppresses high-frequency noise that could degrade ripple rejection or cause oscillation.
Can MC7806ACTG be used in adjustable configurations?
Yes - MC7806ACTG can be configured as an adjustable regulator using external resistors and a Zener diode per Figure 10 in the datasheet. However, doing so voids the factory-trimmed +6.0 V accuracy and introduces additional error sources; dedicated adjustable regulators like LM317 are preferred for variable-output designs.
What is the thermal resistance of MC7806ACTG in TO-220 package?
The MC7806ACTG in TO-220 (Case 221AB) has a junction-to-ambient thermal resistance (RJA) of 92°C/W with no heatsink, and junction-to-case (RJC) of 5.0°C/W. With a properly mounted 1.5°C/W heatsink, total RJA drops to ~20°C/W, enabling 1.0 A continuous operation at ambient temperatures up to +75°C.
Is MC7806ACTG compatible with lead-free soldering processes?
Yes - MC7806ACTG is Pb-free and RoHS-compliant, qualified for standard lead-free reflow profiles (JEDEC J-STD-020, peak 260°C). Its TO-220 package withstands multiple reflow cycles without delamination or parameter shift, supporting both through-hole wave soldering and surface-mount assembly with thermal relief pads.
