Product details
Overview
NCV8715MX15TBG from onsemi is a 50 mA, fixed 1.5 V output, automotive-grade LDO linear voltage regulator in XDFN6 (1.5 × 1.5 mm) package. It operates from 2.5 V to 24 V input, delivers ±2% output accuracy over full load/line/temperature, features ultra-low 5.8 µA max quiescent current, and integrates thermal shutdown and current limiting - designed for infotainment power rails in vehicle head units.
For engineers reviewing the NCV8715MX15TBG datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, real-world automotive use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The NCV8715MX15TBG uses a PMOS pass transistor architecture enabling low dropout (250–400 mV at 50 mA) and stable operation with ceramic output capacitors ≥0.47 µF. Its bandgap reference and error amplifier deliver tight regulation across −40°C to +125°C ambient temperature.
Internal protection includes thermal shutdown triggered at 170°C junction temperature with 15°C hysteresis, and foldback current limiting. PSRR reaches 56 dB at 100 kHz, and output noise is 75 µVRMS (200 Hz–100 kHz), supporting low-noise analog and audio subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% - ensures stable core supply for low-voltage microcontrollers 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). |
| Max Output Current | 50 mA continuous - sufficient for powering CAN transceivers, EEPROMs, or sensor signal chains in safety-critical modules. |
| Quiescent Current | Max 5.8 µA over full load/temperature - enables always-on functionality in body control modules with <10 µA system sleep budget. |
| Dropout Voltage | 250–400 mV at 50 mA - maintains regulation during engine cranking when input drops to 6–7 V while supplying 1.5 V logic. |
| PSRR @ 100 kHz | 56 dB - suppresses high-frequency switching noise from DC-DC converters feeding adjacent subsystems. |
| Thermal Shutdown | 170°C junction with 15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heat sinking. |
Pinout & Package
XDFN6 package (Case 711AE), 1.5 mm × 1.5 mm, 0.5 mm pitch, wettable flank, Pb-free, RoHS-compliant. Exposed thermal pad (EP) connected to GND for enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.5–24 V; requires ≥0.1 µF ceramic decoupling to ground near pin for stability and transient immunity. |
| 2 (N/C) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation via PCB copper pour. |
| 3 (GND) | Power ground reference | Primary return path; must be low-impedance and directly connected to thermal pad for optimal RJA = 260°C/W. |
| 4 (N/C) | No connection | Internally unconnected; optional GND tie for thermal enhancement, not required for electrical function. |
| 5 (N/C) | No connection | Internally unconnected; optional GND tie for thermal enhancement, not required for electrical function. |
| 6 (OUT) | Regulated 1.5 V output | Delivers up to 50 mA; requires ≥0.47 µF ceramic capacitor to ground for loop stability and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +125°C ambient operation - meets automotive electronics reliability requirements without derating. |
| Ultra-low IQ | 4.7 µA typical, 5.8 µA max across full load/temperature - enables >10-year battery life in always-on telematics modules. |
| Wide VIN range | 2.5 V to 24 V - eliminates need for pre-regulation in 12 V/24 V dual-voltage vehicle platforms. |
| Ceramic-capacitor stable | No minimum ESR requirement - allows use of small, low-cost, high-reliability X5R/X7R MLCCs instead of tantalum. |
| Integrated protection | Thermal shutdown + current limiting - prevents field failures due to short circuits or overheating without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8715SQ15T2G | Same die, SC-70-5 (SOT-353) package; RJA = 390°C/W vs. 260°C/W for XDFN6; 3000/reel vs. 3000 or 5000/reel shipping. | Lower thermal performance limits max continuous current in high-ambient designs; suitable for space-constrained but thermally benign layouts. | Select when board area is critical and power dissipation ≤150 mW; avoid in sealed enclosures above 85°C ambient. |
| TLV73315PDBVR | 1.5 V, 300 mA, 65 µA IQ, SOT-23-5; no AEC-Q100 qualification; RJA ≈ 240°C/W; dropout ~250 mV at 300 mA. | Higher current capability but higher quiescent current and non-automotive qualification; lacks thermal hysteresis spec. | Use only in non-automotive industrial or consumer applications where 300 mA load and 65 µA IQ are acceptable trade-offs. |
Compared with NCV8715SQ15T2G, the NCV8715MX15TBG offers superior thermal performance and higher tape-and-reel quantities; compared with TLV73315PDBVR, it delivers automotive qualification and 13× lower quiescent current at the cost of 250 mA lower output capability.

FAQ
What is the maximum input voltage rating for the NCV8715MX15TBG?
The NCV8715MX15TBG has an absolute maximum input voltage of 24 V, with recommended operating range from 2.5 V to 24 V. Operation beyond 24 V risks permanent damage per Absolute Maximum Ratings. The device is designed for automotive battery environments including load-dump transients up to 24 V, but external clamping is advised for sustained >24 V exposure.
Does the NCV8715MX15TBG require an external output capacitor, and what value is recommended?
Yes, the NCV8715MX15TBG requires an external ceramic output capacitor for stability. The datasheet specifies ≥0.47 µF, with X5R or X7R dielectrics recommended for minimal capacitance shift over temperature. A 1.0 µF capacitor is commonly used to balance transient response and board space; larger values (up to 10 µF) improve line transient suppression without compromising stability.
Is the NCV8715MX15TBG pin-compatible with other variants in the NCV8715 family?
No - the NCV8715MX15TBG (XDFN6) is not pin-compatible with SC-70-5 variants like NCV8715SQ15T2G. While both share identical IN, GND, and OUT pin positions, the XDFN6 has three N/C pins (pins 2, 4, 5) versus one N/C in SC-70-5. PCB layout must be redesigned to accommodate the 6-pin, 1.5×1.5 mm footprint and exposed thermal pad.
What is the thermal resistance (RJA) of the NCV8715MX15TBG, and how does it affect power dissipation?
The NCV8715MX15TBG has a typical RJA of 260°C/W when mounted on a standard PCB with 650 mm² copper pour (1 oz). At 50 mA load and 24 V input, power dissipation is ~1.125 W, resulting in ~293°C junction rise - exceeding safe limits. Derating is essential: at 12 V input, dissipation drops to ~0.525 W, yielding ~137°C rise, still requiring careful thermal design or reduced load to stay below 125°C TJ.
How does the NCV8715MX15TBG achieve its ultra-low quiescent current specification?
The NCV8715MX15TBG achieves ≤5.8 µA max IQ through a proprietary low-power bandgap reference and optimized biasing of the PMOS pass element and error amplifier. Quiescent current remains stable across input voltage (2.5–24 V) and temperature (−40°C to +125°C), enabling reliable operation in always-on automotive subsystems without compromising battery drain budgets.
