Product details
Overview
NCV8716MT18TBG from onsemi is an automotive-grade 80 mA low-dropout linear voltage regulator with fixed 1.8 V output, ultra-low quiescent current (max 5.8 µA over temperature), wide 2.8–24 V input range, ±2% output accuracy across load/line/temperature, and integrated thermal shutdown and current limiting. It powers always-on microcontrollers in vehicle body control modules.
For engineers reviewing the NCV8716MT18TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), 60 dB PSRR at 100 kHz, 140 µVRMS output noise (200 Hz–100 kHz), and wDFN6 2×2 mm package with exposed thermal pad.
Technical Context
The NCV8716MT18TBG uses a PMOS pass transistor architecture enabling ultra-low IQ and stable operation down to 2.8 V input while delivering 1.8 V at up to 80 mA. Its bandgap reference and error amplifier maintain ±2% regulation across −40 °C to +125 °C ambient, with dropout voltage as low as 380 mV at 80 mA.
Protection circuitry includes foldback current limiting and thermal shutdown triggered at 155 °C with 25 °C hysteresis. The device requires only a 0.47 µF ceramic output capacitor and is stable with zero-ESR ceramics - no minimum ESR requirement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% over full load (0–80 mA), line (2.8–24 V), and temperature (−40 °C to +125 °C) - ensures reliable MCU core supply under battery transients. |
| Quiescent Current | Max 5.8 µA over temperature - enables >10-year battery life in always-on automotive modules (e.g., door ECU sleep mode). |
| PSRR | 60 dB at 100 kHz - suppresses high-frequency switching noise from DC-DC converters feeding the LDO input. |
| Output Noise | 140 µVRMS (200 Hz–100 kHz) - meets low-noise requirements for analog sensor interfaces and RF power management ICs. |
| Dropout Voltage | 380 mV typical at 80 mA - allows operation with ≤2.18 V input, supporting cold-crank scenarios down to 6 V battery. |
| Thermal Shutdown | 155 °C junction activation with 25 °C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Ambient Range | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin applications without derating. |
Pinout & Package
NCV8716MT18TBG is housed in a thermally enhanced wDFN6 (Case 511BR) package: 2 mm × 2 mm × 0.8 mm body with 0.65 mm pitch and exposed thermal pad (EXP) tied to GND for optimal heat dissipation. RJA = 120 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2.8–24 V; requires ≥0.1 µF ceramic decoupling to ground for stability and transient immunity. |
| 2 - N/C | No connection | May be tied to GND to improve thermal performance; electrically isolated from internal circuitry. |
| 3 - GND | Power ground reference | Main ground return path; must be connected to PCB ground plane and bonded to exposed pad (EXP). |
| 4 - N/C | No connection | May be tied to GND to improve thermal performance; electrically isolated from internal circuitry. |
| 5 - N/C | No connection | May be tied to GND to improve thermal performance; electrically isolated from internal circuitry. |
| 6 - OUT | Regulated 1.8 V output | Delivers up to 80 mA; requires ≥0.47 µF ceramic capacitor to ground for loop stability and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | Max 5.8 µA over temperature enables >10-year battery backup in vehicle access modules without periodic recharge. |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation - supports placement in engine bay, door modules, and seat controllers. |
| No minimum ESR required | Stable with 0.47–10 µF X5R/X7R ceramics - eliminates need for costly tantalum or polymer capacitors and simplifies BOM. |
| High PSRR at 100 kHz | 60 dB rejection of DC-DC switching noise - preserves signal integrity in mixed-signal domains like ADAS sensor hubs. |
| Exposed thermal pad | Integral GND-connected EXP pad reduces thermal resistance by ~30% vs. standard DFN - improves reliability at 80 mA continuous load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73318PDBVR | Lower IQ (2.5 µA typ), but only AEC-Q100 Grade 2 (−40 °C to +105 °C); no thermal shutdown hysteresis. | Not qualified for under-hood use above 105 °C ambient; suitable for cabin-only infotainment modules. | Select when lower quiescent current is critical and ambient temperature stays below 105 °C. |
| TPS78018QDDCRQ1 | Higher IQ (1.4 µA typ), same AEC-Q100 Grade 1, but 50 mA output limit and 250 mV dropout at 50 mA. | Limited to low-power MCUs or sensors; insufficient for 80 mA peak loads in TCU or BCM applications. | Select only for space-constrained designs where 50 mA output suffices and footprint compatibility is prioritized. |
Compared with TLV73318PDBVR and TPS78018QDDCRQ1, the NCV8716MT18TBG uniquely balances 80 mA output, 5.8 µA IQ, full Grade 1 temperature range, and integrated thermal hysteresis - making it the only option meeting all three requirements simultaneously in automotive body electronics.

FAQ
What is the maximum input voltage rating for the NCV8716MT18TBG?
The NCV8716MT18TBG has an absolute maximum input voltage of 24 V, with recommended operating range from 2.8 V to 24 V. This allows direct connection to automotive battery rails, including tolerance for load-dump transients up to 24 V without external clamping. Operation above 24 V risks permanent damage per Absolute Maximum Ratings table.
Does the NCV8716MT18TBG require an external resistor network for output voltage setting?
No, the NCV8716MT18TBG is a fixed-output regulator with factory-trimmed 1.8 V. It contains no feedback pins or external resistor connections - the output voltage is internally set and guaranteed within ±2% across temperature, load, and line variations. No external components are needed to configure VOUT.
Can the NCV8716MT18TBG operate with a 0.1 µF input capacitor?
Yes, the NCV8716MT18TBG is specified to operate stably with a minimum 0.1 µF ceramic (X5R/X7R) capacitor between IN and GND. This value provides sufficient high-frequency decoupling for most automotive applications; larger values (e.g., 1 µF) further improve line transient response without compromising stability.
Is the exposed thermal pad (EXP) on the NCV8716MT18TBG package required to be connected to ground?
Yes, the exposed pad (EXP) must be electrically and thermally connected to Pin 3 (GND) and the PCB ground plane. Table 1 explicitly states "Exposed pad EXP must be tied with GND pin 3." Failure to connect EXP degrades thermal performance and may cause premature thermal shutdown under load.
What is the typical dropout voltage of the NCV8716MT18TBG at 80 mA output current?
The typical dropout voltage of the NCV8716MT18TBG is 380 mV at 80 mA output current, as specified in Table 6 (1.8 V version). This means the device maintains regulation as long as input voltage remains ≥2.18 V (1.8 V + 0.38 V), supporting operation during automotive cold-crank conditions down to 6 V battery voltage.
