Product details
Overview
NCV8716MT28TBG from onsemi is an automotive-grade 2.8 V fixed-output, 80 mA ultra-low-quiescent-current LDO linear voltage regulator in a wDFN6 (2×2 mm) package. It operates from 2.5 V to 24 V input, delivers ±2% output accuracy over load/line/temperature, features 5.8 µA max quiescent current, and integrates thermal shutdown and current limiting - designed for always-on power domains in vehicle body control modules and infotainment subsystems.
For engineers reviewing the NCV8716MT28TBG datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, confirmed automotive-grade specifications (AEC-Q100 Grade 1, −40 °C to +125 °C), and real-world design implications for low-power, wide-input-voltage regulation in safety-critical embedded systems.
Technical Context
The NCV8716MT28TBG implements a PMOS pass transistor architecture enabling ultra-low ground current (≤5.8 µA) across full load and temperature range. Its internal bandgap reference, UVLO, and MOSFET driver with current-limit protection operate independently of output capacitor ESR, supporting stable regulation with ceramic capacitors ≥0.47 µF.
Thermal shutdown triggers at 155 °C with 25 °C hysteresis, and dropout voltage is characterized at 380–600 mV under 80 mA load. PSRR reaches 58 dB at 100 kHz, and output noise is 180 µVRMS (200 Hz–100 kHz), making it suitable for noise-sensitive analog and MCU core rails in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2% over full load, line, and temperature - ensures reliable biasing of 2.8 V logic and sensors without external feedback. |
| Input Voltage Range | 2.5 V to 24 V - supports direct connection to automotive battery (cold-crank down to ~6 V, load-dump up to 24 V) without pre-regulation. |
| Quiescent Current | Max 5.8 µA at 24 V input and full −40 °C to +125 °C range - enables multi-year battery life in always-on telematics and gateway modules. |
| Dropout Voltage | 380–600 mV at 80 mA - allows regulation from 3.18 V input, critical for post-buck or backup-supply operation in low-voltage domains. |
| PSRR | 58 dB at 100 kHz - suppresses high-frequency switching noise from DC-DC converters feeding adjacent analog circuitry. |
| Thermal Shutdown | 155 °C junction with 25 °C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking in enclosed ECUs. |
| Package | wDFN6, 2 mm × 2 mm, 0.65 mm pitch, exposed thermal pad - enables compact layout and efficient heat transfer to PCB ground plane. |
Pinout & Package
Package: wDFN6 (Case 511BR), 2 mm × 2 mm × 0.8 mm, with exposed thermal pad (EXP) tied to GND for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply | Accepts 2.5–24 V; requires ≥0.1 µF ceramic decoupling to GND close to pin for transient immunity and stability. |
| 2 (N/C) | No connection | May be tied to GND to improve thermal dissipation; no electrical function. |
| 3 (GND) | Power ground | Main return path; must be connected to PCB ground plane and bonded to exposed pad (EXP) for thermal and electrical integrity. |
| 4 (N/C) | No connection | May be tied to GND to improve thermal dissipation; no electrical function. |
| 5 (N/C) | No connection | May be tied to GND to improve thermal dissipation; no electrical function. |
| 6 (OUT) | Regulated output | Delivers stable 2.8 V; requires ≥0.47 µF ceramic capacitor to GND for loop stability and load-transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C ambient operation - meets automotive electronics reliability requirements for engine bay and cabin modules. |
| Ultra-low IQ | ≤5.8 µA across full temperature and load range - minimizes standby power loss in battery-backed systems like keyless entry and alarm controllers. |
| ESD robustness | 2000 V HBM, 200 V MM - withstands handling and board-level ESD events common in automotive manufacturing and service environments. |
| Zero-ESR capacitor compatibility | Stable with ceramic capacitors ≥0.47 µF - eliminates need for tantalum or aluminum electrolytics, reducing BOM cost and size. |
| Thermal shutdown with hysteresis | 155 °C trip, 25 °C hysteresis - prevents thermal runaway while allowing safe recovery after fault removal without oscillation. |
Applications
| Body Control Module (BCM) | Infotainment Power Sequencing |
|---|---|
|

Use Scenario: Providing clean 2.8 V rail to audio codec and touch controller in head-unit infotainment during boot and runtime. IC Role / Device Role / Timing Role: Secondary LDO in multi-rail power tree, decoupled from noisy DC-DC sources via high PSRR and low noise. Use Value: Reduces audible noise and touch jitter by suppressing 100 kHz switching artifacts from upstream buck converters. |
| Telematics Control Unit (TCU) | ADAS Camera Module |
|
Use Scenario: Powering GPS/GNSS baseband processor and cellular modem RF front-end in always-connected TCU. IC Role / Device Role / Timing Role: Low-IQ LDO supplying 2.8 V to precision timing circuits and low-power microcontrollers. Use Value: Extends battery backup duration >72 hours during vehicle ignition-off, ensuring continuous location tracking and firmware updates. |
Use Scenario: Delivering regulated 2.8 V to image sensor analog front-end and ISP core in rear-view or surround-view camera modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8716MT33TBG | Fixed 3.3 V output; identical package, quiescent current, and protection features. | Used where downstream logic or interfaces require 3.3 V instead of 2.8 V - not drop-in compatible due to output voltage mismatch. | Select only if system voltage rail requirements align with 3.3 V; verify all connected loads tolerate higher nominal voltage. |
| TLV73328PDBVR | 2.8 V output, 300 mA rating, 65 µA typical IQ, SOT-23-5 package - higher current but 10× higher quiescent current. | Suitable for non-automotive industrial or consumer applications where AEC-Q100 is not required and higher IQ is acceptable. | Choose when higher output current is needed and automotive qualification is unnecessary; avoid in battery-critical automotive designs. |
Compared with NCV8716MT28TBG, the NCV8716MT33TBG offers identical automotive qualification and ultra-low IQ but targets 3.3 V systems, while TLV73328PDBVR trades AEC-Q100 compliance and sub-6 µA IQ for higher output current and smaller footprint - neither is pin-compatible, requiring PCB redesign.

FAQ
Is NCV8716MT28TBG still in active production?
No, NCV8716MT28TBG is officially discontinued per onsemi's datasheet revision 7 (February 2026). It remains available through Aetrix Electronics' legacy component channel with full traceability and extended lifecycle support for existing production programs.
What is the maximum output current capability of NCV8716MT28TBG?
The NCV8716MT28TBG is rated for 80 mA continuous output current, with a short-circuit current limit protecting the device. Absolute maximum ratings allow brief 110 mA peak, but sustained operation above 80 mA risks thermal shutdown or reduced lifetime.
Can NCV8716MT28TBG be used with ceramic output capacitors?
Yes, NCV8716MT28TBG is explicitly designed for zero-ESR ceramic capacitors. A minimum 0.47 µF X5R or X7R ceramic capacitor is required from OUT to GND for stability, and values up to 10 µF improve transient response without risk of oscillation.
Does NCV8716MT28TBG require an input capacitor?
Yes, NCV8716MT28TBG requires at least a 0.1 µF ceramic capacitor between IN and GND. This decouples high-frequency noise and limits voltage spikes caused by PCB trace inductance during load transients - placement within 2 mm of the IN pin is critical.
What does the "NCV" prefix signify for NCV8716MT28TBG?
The "NCV" prefix indicates that NCV8716MT28TBG is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), manufactured under automotive-specific process controls, and PPAP-capable - meeting requirements for safety-critical vehicle subsystems.
