Product details
Overview
NCV8718AMT330TBG from onsemi is a 300 mA, fixed 3.3 V output, automotive-grade LDO linear voltage regulator in WDFN6 2×2 mm package. It delivers ±2% output accuracy over full load/line/temperature, ultra-low 4 µA quiescent current, and operates from 2.5 V to 24 V input - enabling use in automotive infotainment power rails where low standby consumption and wide VIN tolerance are critical.
For engineers reviewing the NCV8718AMT330TBG datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (285–450 mV at 300 mA), PSRR (60 dB @ 1 kHz), thermal shutdown (165°C), SOA limiting, and AEC-Q100 Grade 1 qualification for −40°C to +125°C ambient operation.
Technical Context
The NCV8718AMT330TBG integrates a bandgap reference, MOSFET driver with current limiting, thermal shutdown circuitry, and integrated soft-start logic. Its enable-controlled operation supports microprocessor sequencing, while SOA limiting protects against simultaneous high-VIN/high-IOUT stress conditions.
This fixed-output variant uses internal resistor feedback for 3.3 V regulation and omits external ADJ pin connection; Pin 2 is NC (no connect), not functional as feedback. Stability is ensured with only 1 µF ceramic input/output capacitors - no ESR requirement - making it suitable for space-constrained automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% over full load, line, and temperature - ensures reliable MCU core or interface rail regulation without external feedback tuning. |
| Max Output Current | 300 mA continuous - sufficient for powering single-core microcontrollers, CAN transceivers, or sensor signal chains in telematics modules. |
| Quiescent Current | Typ. 4 µA over −40°C to +125°C - enables >10-year battery life in always-on vehicle subsystems like door modules or tire pressure sensors. |
| Dropout Voltage | 285–450 mV at 300 mA (depending on VOUT bin) - allows stable 3.3 V output even when input drops to 3.585 V, supporting cold-crank scenarios. |
| PSRR | 60 dB at 1 kHz - suppresses ripple from switching pre-regulators (e.g., buck converters), reducing noise coupling into sensitive analog or RF sections. |
| Thermal Shutdown | 165°C junction activation with 25°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking in sealed enclosures. |
| Package | WDFN6 2×2 mm, 0.65 mm pitch - compact footprint compatible with automated SMT assembly and offers low thermal resistance (RJA = 65°C/W). |
Pinout & Package
Package: WDFN6 2×2 mm, exposed thermal pad, RoHS-compliant, Pb-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 3.3 V; requires 1 µF ceramic capacitor to GND for stability and transient response. |
| 2 - NC / ADJ | No connection (fixed version) | Not connected internally; may be tied to GND for improved thermal dissipation but must not be used as feedback. |
| 3,6 - GND | Power ground | Dual ground pins reduce impedance path; both must be connected to low-impedance PCB ground plane for noise and thermal performance. |
| 4 - EN | Enable control input | Active-high logic: ≥1.2 V enables regulator; ≤0.4 V disables, reducing IQ to 0.1 µA - enables system-level power gating. |
| 5 - NC | No connection | Internally unconnected; may be tied to GND for thermal enhancement or left floating. |
| 6 - IN | Input supply | Accepts 2.5–24 V; requires 1 µF ceramic decoupling capacitor close to pin to suppress high-frequency noise and trace inductance effects. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 4 µA typical across −40°C to +125°C - extends battery runtime in always-on automotive ECUs without compromising regulation accuracy. |
| Soft-start circuitry | Integrated ramp-up limits inrush current and output overshoot during power-on - eliminates need for external RC timing networks. |
| SOA limiting | Dynamic and static safe-operating-area protection prevents thermal runaway under high VIN/high IOUT combinations - critical for 12 V/24 V vehicle systems. |
| Stable with 1 µF ceramic caps | No minimum ESR requirement - enables use of small, low-cost X5R/X7R MLCCs instead of larger tantalum or polymer capacitors. |
| AEC-Q100 Grade 1 | Qualified for −40°C to +125°C ambient operation - meets automotive reliability and lifetime requirements for front-end and cabin electronics. |
Applications
| Infotainment Power Rail | In-Vehicle Networking Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73333PDBVR | 300 mA, 3.3 V fixed, 65 µA IQ, SOT-23-5 package, no AEC-Q100 qualification | Limited to industrial/consumer use; lacks automotive temp range and thermal shutdown hysteresis | Choose for cost-sensitive non-automotive designs where ultra-low IQ is not required and layout space allows SOT-23. |
| TPS7B8233QDGNRQ1 | 300 mA, 3.3 V fixed, 3.5 µA IQ, 6-pin WSON, AEC-Q100 Grade 1, but no SOA limiting | Missing dynamic SOA protection - less robust under combined high-VIN/high-IOUT stress common in 24 V truck systems | Prefer where ultra-low IQ is primary and SOA stress is mitigated by upstream design; verify thermal derating per application. |
Compared with TLV73333PDBVR and TPS7B8233QDGNRQ1, the NCV8718AMT330TBG uniquely combines AEC-Q100 Grade 1, SOA limiting, and 4 µA IQ in a 2×2 mm WDFN6 - making it the only option qualified for harsh automotive environments requiring simultaneous low-power standby and high-stress operational resilience.

FAQ
What is the output voltage tolerance of the NCV8718AMT330TBG over temperature and load?
The NCV8718AMT330TBG provides ±2% output voltage accuracy across −40°C to +125°C ambient temperature, full load range (0.1 mA to 300 mA), and input voltage variation (2.5 V to 24 V). This specification is guaranteed per Table 5 in the datasheet and applies directly to the 3.3 V fixed-output variant, ensuring consistent performance in automotive cabin and engine bay environments.
Does the NCV8718AMT330TBG require an external feedback resistor network?
No, the NCV8718AMT330TBG is a fixed-output 3.3 V regulator with internal feedback. Pin 2 (NC/ADJ) is not connected internally and must remain unconnected or tied to GND for thermal improvement - it is not used for voltage setting. External resistors are only required for adjustable versions like NCV8718AMTADJTBG.
What is the maximum input voltage the NCV8718AMT330TBG can withstand?
The NCV8718AMT330TBG has an absolute maximum input voltage rating of 24 V, as specified in Table 2 of the datasheet. Operation above this level risks permanent damage. For reliable long-term use, the recommended operating input range is 2.5 V to 24 V, with proper input decoupling to handle transients common in automotive 12 V/24 V systems.
How does the enable (EN) pin function on the NCV8718AMT330TBG?
The EN pin on the NCV8718AMT330TBG is active-high: applying ≥1.2 V enables regulation, while ≤0.4 V disables the output and reduces quiescent current to 0.1 µA. The pin draws only 100 nA at 5.5 V, enabling direct interfacing with low-power microcontrollers or CAN wake signals without additional level-shifting circuitry.
Is the NCV8718AMT330TBG qualified for automotive applications?
Yes, the NCV8718AMT330TBG carries the NCV prefix indicating automotive qualification: it is AEC-Q100 Grade 1 certified (−40°C to +125°C ambient), PPAP-capable, and manufactured under automotive-specific process controls. Its SOA limiting, thermal shutdown, and wide-input capability make it suitable for infotainment, telematics, and body electronics in production vehicles.
