Product details
Overview
NCV8606MN18T2G from onsemi is an automotive-grade, 500 mA low-dropout (LDO) linear regulator with enable pin, fixed 1.8 V output, ±2% tolerance over all operating conditions, 175°C thermal shutdown, and 4 kV HBM ESD rating. It delivers stable power to microcontrollers and sensors in battery-powered automotive infotainment and ADAS modules.
For engineers reviewing the NCV8606MN18T2G datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, confirmed automotive qualification status (AEC-Q100), real-world load/line transient performance, and two rigorously cross-checked alternative parts for 1.8 V LDO replacement scenarios.
Technical Context
The NCV8606MN18T2G integrates a PMOS pass transistor with current-limit protection (675 mA), thermal shutdown (175°C), and an active-high enable input that controls regulator activation without external circuitry. Its architecture supports operation down to 1.5 V input while maintaining regulation at 1.8 V output.
It achieves 62 dB PSRR at 120 Hz and 50 µVRMS integrated output noise (10 Hz–100 kHz) without requiring a bypass capacitor, enabling clean power delivery to noise-sensitive analog and RF subsystems in automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% over −40°C to +125°C ambient; ensures stable core voltage for 1.8 V logic in automotive environments. |
| Max Output Current | 500 mA continuous; sufficient for powering multiple low-power MCUs or sensor clusters from a single rail. |
| Dropout Voltage | 250 mV at 500 mA (1.8 V output); enables operation from partially discharged 3.3 V or 5 V supplies with minimal headroom loss. |
| PSRR | 62 dB @ 120 Hz; suppresses ripple from switching pre-regulators feeding downstream analog circuits. |
| Ground Current | 145 µA typical at full load; minimizes quiescent power draw during vehicle sleep modes. |
| Enable Threshold | VEN(H) = 0.9 V, VEN(L) = 0.4 V; compatible with standard 3.3 V or 5 V GPIO control without level-shifting. |
| Thermal Shutdown | 175°C with 10°C hysteresis; prevents latch-up during sustained overload or poor PCB thermal design. |
Pinout & Package
NCV8606MN18T2G is housed in a thermally enhanced DFN6 3.0×3.3 mm package (Case 506AX) with exposed pad tied to GND for improved heat dissipation and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6 | Vin | Positive input supply; pins 1 and 6 must be externally shorted to support full 500 mA output current capability. |
| 2 | GND | Power ground reference; connects to exposed pad for optimal thermal and electrical performance. |
| 3 | EN | Active-high enable input; drives regulator ON when ≥0.9 V, OFF when ≤0.4 V; disable current <1 µA. |
| 4 | Vout | Regulated 1.8 V output; requires ≥1 µF ceramic capacitor placed adjacent to pin for stability and transient response. |
| 5 | SENSE/ADJ | Output voltage sense node; for fixed-output versions like NCV8606MN18T2G, directly connected to Vout capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Qualified for automotive applications per Grade 1 (−40°C to +125°C junction), PPAP-capable with unique site control. |
| Low-noise operation | 50 µVRMS output noise (10 Hz–100 kHz) without external bypass capacitor-reduces BOM count and board space. |
| High PSRR at low frequency | 62 dB rejection at 120 Hz enables clean power delivery even when fed from noisy DC-DC converters. |
| Robust protection suite | Integrated thermal shutdown (175°C), current limit (675 mA), and short-circuit protection prevent field failures. |
| Pb-free & RoHS compliant | Meets automotive environmental standards; DFN6 package supports reflow soldering per J-STD-020. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73318PDBVR | 300 mA max output, 220 mV dropout at 300 mA, no AEC-Q100 qualification, 1.8 V ±1.5% tolerance. | Suitable for industrial or consumer portable devices-not certified for automotive use. | Select when cost sensitivity outweighs automotive qualification requirements and 300 mA load suffices. |
| NCP1117ST18T3G | 1 A output, 1.2 V dropout at 800 mA, TO-220/TO-263 package, ±2% tolerance, no enable pin, not AEC-Q100 qualified. | Used in non-automotive power supplies where thermal mass and PCB area allow larger packages. | Choose only if higher current and through-hole mounting are acceptable, and automotive compliance is unnecessary. |
Compared with TLV73318PDBVR and NCP1117ST18T3G, the NCV8606MN18T2G uniquely combines AEC-Q100 Grade 1 qualification, 500 mA output in a 3.0×3.3 mm DFN, enable control, and automotive-grade ESD (4 kV HBM), making it the sole option for safety-critical 1.8 V LDO applications in modern vehicles.

FAQ
What is the maximum input voltage for the NCV8606MN18T2G?
The absolute maximum input voltage for the NCV8606MN18T2G is 6.5 V. However, the recommended operating input range is 1.5 V to 6.0 V. Operation below 1.5 V or above 6.0 V risks violating safe operating area limits and may trigger thermal shutdown or damage the device. The minimum valid input depends on dropout: for 1.8 V output, Vin must be ≥2.05 V (1.8 V + 250 mV typical dropout) to maintain regulation at full load.
Does the NCV8606MN18T2G require external capacitors for stability?
Yes, the NCV8606MN18T2G requires a minimum 1.0 µF ceramic input capacitor (Cin) placed close to pins 1/6 and a minimum 1.0 µF ceramic output capacitor (Cout) placed adjacent to pin 4. These capacitors ensure stability, improve line/load transient response, and reduce noise. Larger values (e.g., 10 µF) further enhance transient performance but are not mandatory for basic operation.
Is the NCV8606MN18T2G pin-compatible with the NCV8605MN18T2G?
No, the NCV8606MN18T2G is not pin-compatible with the NCV8605MN18T2G. While both share the same DFN6 package and pin 1/6 (Vin), pin 3 is EN (active-high enable) on the NCV8606MN18T2G but NC (no connection) on the NCV8605MN18T2G. Interchanging them without board revision will leave the enable function unconnected or cause unintended activation.
What is the thermal resistance of the NCV8606MN18T2G in standard layout?
The NCV8606MN18T2G has a junction-to-ambient thermal resistance (RJA) of 75°C/W when soldered on a 645 mm², 1 oz copper FR4 PCB. This value assumes optimal thermal land pattern including the exposed pad connected to a solid GND plane. With this layout, the device can dissipate up to 1.3 W at 25°C ambient before reaching its 150°C maximum junction temperature.
How does the enable pin behave during power-up sequences?
The NCV8606MN18T2G enable pin has a logic-high threshold of 0.9 V and logic-low threshold of 0.4 V, with hysteresis ensuring noise immunity. When EN rises above 0.9 V, the regulator turns on with a typical enable time of 13 µs (for 1.8 V output). If EN is left floating, internal leakage may cause unpredictable behavior; it must be pulled to Vin or GND via a resistor to guarantee defined state.
