Product details
Overview
NCV8715MX18TBG from onsemi is a 50 mA, fixed 1.8 V output, ultra-low quiescent current (max 5.8 µA) LDO linear voltage regulator with 2.8 V to 24 V input range, ±2% output accuracy over load/line/temperature, and AEC-Q100 Grade 1 qualification for automotive infotainment and safety systems.
For engineers reviewing the NCV8715MX18TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.8 V fixed output, XDFN6 1.5 × 1.5 mm package, thermal shutdown protection, dropout voltage of 230–350 mV at 50 mA, and PSRR of 60 dB at 100 kHz.
Technical Context
The NCV8715MX18TBG integrates a bandgap reference, MOSFET driver with current limiting, UVLO, and thermal shutdown circuitry in a single monolithic IC. Its architecture enables stable regulation across wide input voltage swings while maintaining ultra-low ground current across temperature and load.
It operates without requiring minimum ESR output capacitors and is stable with ceramic capacitors ≥0.47 µF. The device's internal protection includes current limiting and thermal shutdown with 170°C trip point and 15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V, ±2% accuracy over −40°C to +125°C ambient, 0–50 mA load, and 3.0–24 V input. |
| Input Voltage Range | 2.8 V to 24 V - supports direct battery connection in 12 V automotive systems with cold-crank margin. |
| Quiescent Current | Max 5.8 µA at full load and temperature - enables always-on subsystems with microamp-level standby power. |
| Dropout Voltage | 230–350 mV at 50 mA - allows regulation down to VIN = 2.15 V, critical for low-voltage brownout resilience. |
| PSRR | 60 dB at 100 kHz - suppresses high-frequency switching noise from upstream DC-DC converters. |
| Thermal Shutdown | 170°C junction trip with 15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heat sinking. |
| Package | XDFN6 1.5 × 1.5 mm, 0.5 mm pitch - compact footprint suitable for space-constrained automotive modules. |
Pinout & Package
XDFN6 (Case 711AE) package with wettable flank leads for automated optical inspection; 6-pin layout with two no-connect (N/C) pins optimized for thermal dissipation when tied to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.8–24 V; requires ≥0.1 µF ceramic decoupling to GND for stability and transient immunity. |
| 2 (N/C) | No connection | Internally unconnected; may be soldered to ground plane to enhance thermal performance (RJA = 260°C/W). |
| 3 (GND) | Power ground reference | Primary return path; must be low-impedance and directly connected to system ground plane. |
| 4 (N/C) | No connection | Internally unconnected; optional ground tie for improved thermal dissipation and EMI reduction. |
| 5 (N/C) | No connection | Internally unconnected; unused pin - no electrical function, but grounding improves thermal resistance. |
| 6 (OUT) | Regulated 1.8 V output | Delivers up to 50 mA; requires ≥0.47 µF ceramic capacitor to GND for loop stability and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation - meets automotive reliability and stress-test requirements. |
| Ultra-low IQ (≤5.8 µA) | Enables >10-year battery life in always-on vehicle modules (e.g., CAN wake-up receivers, sensor hubs). |
| Wide VIN range (2.8–24 V) | Eliminates need for pre-regulation in 12 V/24 V systems - supports start-stop, load-dump, and cold-crank conditions. |
| No minimum ESR requirement | Stable with low-ESR ceramic capacitors (0.47–10 µF), reducing BOM cost and board area vs. tantalum alternatives. |
| 1.8 V fixed output | Directly powers modern low-voltage MCUs, FPGAs, and memory interfaces without external feedback resistors. |

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 output, 4 µA IQ, SOT-23-5 package, no AEC-Q100 qualification | Higher current capability but lacks automotive qualification and thermal robustness (TJMAX = 150°C only) | Select for non-automotive industrial or consumer designs needing higher output current and lower IQ. |
| NCP114AMX18T2G | 150 mA output, 2.5 µA IQ, SC-70-5 package, AEC-Q100 Grade 1, but 2.2–5.5 V input range | Narrower input range limits use in 24 V systems or under cold-crank; smaller package has higher RJA (390°C/W) | Select when board space is constrained and input stays within 2.2–5.5 V - not suitable for direct 12 V/24 V battery tie. |
Compared with TLV73318PDBVR and NCP114AMX18T2G, the NCV8715MX18TBG uniquely combines AEC-Q100 Grade 1, 24 V input tolerance, and XDFN6 thermal performance - making it the only qualified option for under-hood 1.8 V LDO applications demanding both wide VIN and automotive reliability.

FAQ
What is the maximum input voltage rating for the NCV8715MX18TBG?
The NCV8715MX18TBG has an absolute maximum input voltage rating of 24 V, with recommended operating range from 2.8 V to 24 V. This allows direct connection to 12 V automotive batteries including load-dump transients up to 24 V, provided external clamping or filtering is used per system-level requirements.
Does the NCV8715MX18TBG require an external resistor network to set output voltage?
No - the NCV8715MX18TBG is a fixed-output LDO with internally trimmed 1.8 V regulation. It does not use external feedback resistors; the output voltage is factory-set and guaranteed within ±2% across temperature, line, and load conditions.
What is the thermal resistance (RJA) of the NCV8715MX18TBG in its XDFN6 package?
The NCV8715MX18TBG in XDFN6 package has a typical junction-to-air thermal resistance (RJA) of 260°C/W when mounted on a PCB with 650 mm² copper heat-spreading area and 1 oz copper thickness - significantly lower than the SC-70 variant's 390°C/W.
Can the NCV8715MX18TBG operate with a 0.47 µF output capacitor?
Yes - the NCV8715MX18TBG is explicitly designed to be stable with ceramic output capacitors as low as 0.47 µF (X5R/X7R), eliminating minimum ESR requirements and enabling compact, low-cost decoupling solutions.
Is the NCV8715MX18TBG qualified for automotive applications?
Yes - the NCV8715MX18TBG carries the NCV prefix indicating automotive qualification, is AEC-Q100 Grade 1 certified (−40°C to +125°C ambient), PPAP-capable, and manufactured in onsemi's IATF 16949-certified facilities.
