Product details
Overview
MC7806CTG 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 transient load stability are critical.
For engineers reviewing the MC7806CTG datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (2.0 V at 1.0 A), output tolerance (±4% for C-grade), ripple rejection (≥56 dB at 120 Hz), and thermal resistance (RJA = 92 °C/W, RJC = 5.0 °C/W).
Technical Context
The MC7806CTG implements a monolithic series pass transistor architecture with built-in protection circuitry: thermal overload sensing triggers shutdown before junction temperature exceeds +150 °C, while short-circuit current limiting caps peak output at 0.2 A under fault conditions. Safe-area compensation dynamically reduces short-circuit current as VIN–VOUT increases, preventing second breakdown.
It operates without external components for basic regulation but requires input bypassing (≥0.33 µF) when located >10 cm from bulk filter. Output capacitance (≥0.1 µF) improves transient response but is not required for stability - values below 0.1 µF may cause oscillation per datasheet guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +6.0 V nominal; ±4% tolerance over full load (5 mA–1.0 A), line (8.0–20 V), and temperature (0–125 °C) range |
| Output Current | 1.0 A continuous; 2.2 A peak (pulse-tested); internally limited to 0.2 A during short-circuit |
| Dropout Voltage | 2.0 V at 1.0 A and 25 °C - defines minimum headroom needed between input and output |
| Ripple Rejection | 56 dB min at 120 Hz (11.5–18 V input) - suppresses AC ripple from unregulated DC sources |
| Quiescent Current | 3.3 mA typical; ≤6.0 mA max - determines no-load power loss in standby operation |
| Thermal Resistance | RJC = 5.0 °C/W (junction-to-case); RJA = 92 °C/W (junction-to-ambient, TO-220, no heatsink) |
| Operating Junction Temp | +150 °C maximum - sets absolute upper limit for thermal design margin |
Pinout & Package
MC7806CTG uses the industry-standard TO-220-3 package (Case 221AB), with metal tab electrically connected to Pin 2 (Ground). Heatsinking is mandatory for >500 mA continuous operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Input | Unregulated DC input; must be ≥8.0 V (min) and ≤35 V (abs max) for stable +6 V output |
| Pin 2 | Ground | Common reference for input and output; metal tab is tied to this pin - must be thermally and electrically connected to PCB ground plane |
| Pin 3 | Output | Regulated +6.0 V output; capable of sourcing up to 1.0 A with adequate heatsinking and input headroom |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | Self-contained regulation - eliminates need for feedback resistors or compensation networks in standard applications |
| Internal thermal shutdown | Automatically disables output when TJ reaches +150 °C, preventing permanent damage during overload or poor heatsinking |
| Short-circuit current limiting | Clamps fault current to ≤0.2 A at 35 V input - protects regulator and upstream supply during wiring faults or load shorts |
| Safe-area compensated pass transistor | Reduces short-circuit current as VIN–VOUT rises - prevents secondary breakdown in high-differential-voltage fault conditions |
| Pb-free and RoHS compliant | Meets environmental compliance requirements for industrial and automotive end equipment without lead-based solder concerns |
Applications

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 |
|---|---|---|---|
| LM7806CDT/NOPB (TI) | Same +6 V output, 1.0 A rating, TO-220 package; ±2% tolerance (tighter than MC7806CTG's ±4%), higher RJA (100 °C/W) | Better initial accuracy suits precision analog rails; lower thermal efficiency requires larger heatsink at full load | Select when tighter output tolerance is prioritized over thermal performance in space-constrained designs |
| NCV7806BD2TR4G (onsemi) | Automotive-grade variant (AEC-Q100 qualified); same electrical specs but enhanced ESD (2 kV HBM) and extended temp range (-40 to +150 °C) | Required for under-hood or safety-critical automotive modules; supports PPAP documentation and zero-defect manufacturing traceability | Select for automotive OEM programs requiring qualification evidence and long-term supply assurance |
Compared with LM7806CDT/NOPB, MC7806CTG offers better thermal resistance (92 vs. 100 °C/W) for compact heatsinks, while NCV7806BD2TR4G adds automotive reliability features at no cost to core regulation performance - making MC7806CTG optimal for industrial and commercial cost-sensitive designs.

FAQ
What is the minimum input voltage required for stable operation of the MC7806CTG?
The MC7806CTG requires a minimum input voltage of 8.0 V DC to maintain regulated +6.0 V output across its full operating range (5 mA–1.0 A load, 0–125 °C). This accounts for the 2.0 V dropout voltage plus margin for ripple and line regulation - input below 8.0 V risks output collapse or unregulated behavior. Datasheet specifies 8.0–20 V for optimal performance.
Does the MC7806CTG require input and output capacitors for stable operation?
Yes - the MC7806CTG requires a minimum 0.33 µF input capacitor (tantalum or low-ESR ceramic) placed directly across Pins 1 and 2 to prevent oscillation, especially with long input traces. An output capacitor (≥0.1 µF) is not mandatory for stability but strongly recommended to improve transient response; values below 0.1 µF may cause instability per datasheet Figure 1 and Application Information section.
Can the MC7806CTG be used in parallel to increase output current?
No - the MC7806CTG is not designed for parallel operation. Its output voltage tolerance (±4%) and lack of current-sharing circuitry mean mismatched units will not share load evenly, risking thermal runaway in one device. For >1.0 A, use a single higher-current regulator (e.g., MC7812CTG with external pass transistor per Figure 11) or switch to a switching solution.
What is the thermal shutdown threshold and recovery behavior of the MC7806CTG?
The MC7806CTG activates thermal shutdown at +150 °C junction temperature, disabling output until junction cools to approximately +130 °C (typical hysteresis ~20 °C). Recovery is automatic and does not require power cycle. During shutdown, quiescent current drops to <1 mA - minimizing residual heating. Full thermal protection is guaranteed only with proper heatsinking per RJC = 5.0 °C/W.
Is the MC7806CTG pin-compatible with older 7806 variants from other manufacturers?
Yes - the MC7806CTG uses the standard TO-220-3 footprint and pinout (Pin 1 = Input, Pin 2 = Ground, Pin 3 = Output), matching legacy 7806 devices from Fairchild, STMicroelectronics, and TI. Mechanical dimensions, thermal pad connection, and electrical characteristics align with JEDEC TO-220 standards, enabling direct replacement in existing designs without layout changes.
