Product details
Overview
NCV8715MX12TBG from onsemi is a 50 mA, 1.2 V fixed-output automotive-grade LDO 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 load/line/temperature, features ultra-low 5.8 µA max quiescent current, and integrates thermal shutdown and current limiting. It powers low-power microcontrollers and sensors in infotainment and safety systems.
For engineers reviewing the NCV8715MX12TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 Grade 1 qualification (−40°C to +125°C), 260°C/W junction-to-air thermal resistance in XDFN6, 230–350 mV dropout at 50 mA, 60 dB PSRR at 100 kHz, and 65 µVRMS output noise (200 Hz–100 kHz).
Technical Context
The NCV8715MX12TBG uses a bandgap reference and MOSFET pass element to achieve stable 1.2 V regulation across wide input (2.5–24 V) and temperature (−40°C to +125°C) ranges. Its internal UVLO prevents operation below safe input thresholds, and thermal shutdown activates at 170°C with 15°C hysteresis.
It requires no minimum ESR output capacitor and remains stable with 0.47 µF to 10 µF ceramic capacitors. Ground current stays constant (≤5.8 µA) from zero to full 50 mA load, enabling ultra-low-power always-on applications such as CAN transceiver biasing and sensor wake-up circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2% over full load, line, and temperature - ensures reliable logic-level supply for 1.2 V core rails. |
| Input Voltage Range | 2.5 V to 24 V - supports direct battery connection in 12 V automotive systems with cold-crank tolerance. |
| Max Output Current | 50 mA continuous - sufficient for powering MCU peripherals, EEPROMs, and low-power sensors. |
| Quiescent Current | Max 5.8 µA over full load and temperature - enables >10-year battery life in always-on vehicle modules. |
| Dropout Voltage | 230–350 mV at 50 mA - allows regulation down to VIN = 1.43 V, critical for deep battery discharge scenarios. |
| PSRR | 60 dB at 100 kHz - suppresses high-frequency switching noise from DC-DC converters feeding the LDO input. |
| Output Noise | 65 µVRMS (200 Hz–100 kHz) - meets stringent noise requirements for analog sensor signal chains. |
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 improves thermal dissipation (RJA = 260°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.5–24 V; requires ≥0.1 µF ceramic decoupling to GND for stability and transient immunity. |
| 2 (N/C) | No connection | Thermally conductive but electrically isolated; may be tied to GND to enhance PCB heat spreading. |
| 3 (GND) | Power ground reference | Low-impedance return path; must connect directly to solid ground plane beneath thermal pad. |
| 4 (N/C) | No connection | Thermally conductive but electrically isolated; optional GND tie for improved thermal performance. |
| 5 (N/C) | No connection | Thermally conductive but electrically isolated; optional GND tie for improved thermal performance. |
| 6 (OUT) | Regulated 1.2 V output | Stable 1.2 V source; requires ≥0.47 µF ceramic capacitor to GND; supports up to 50 mA load. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation - suitable for engine bay and ADAS ECU deployments. |
| Ultra-low ground current | ≤5.8 µA across full load/temperature - enables energy harvesting and battery-backed memory retention. |
| Wide input range | 2.5 V to 24 V - eliminates need for pre-regulation in 12 V/24 V dual-battery architectures. |
| Thermal shutdown with hysteresis | Triggers at 170°C, releases at 155°C - prevents latch-up during sustained overload or poor heatsinking. |
| No minimum ESR requirement | Stable with 0.47–10 µF X5R/X7R ceramics - simplifies BOM and reduces cost vs. tantalum or polymer alternatives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8715SQ12T2G | Same silicon, SC-70-5 (SOT-353) package; RJA = 390°C/W; 3000/reel shipping. | Higher thermal resistance limits power handling in high-ambient environments; smaller footprint but lower thermal performance. | Select when board space is constrained and power dissipation ≤150 mW; avoid for >40°C ambient with >30 mA load. |
| TLD1117LV12 | 1.2 V, 150 mA, 60 µA IQ, SOT-223; not AEC-Q100 qualified; ±1% accuracy. | Lacks automotive qualification and ultra-low IQ; higher noise (120 µVRMS) and lower PSRR (45 dB @ 100 kHz). | Acceptable for non-safety industrial applications where cost outweighs qualification and noise requirements. |
Compared with NCV8715SQ12T2G, the NCV8715MX12TBG offers superior thermal performance (260 vs. 390°C/W) and higher tape-and-reel volume (5000 units), while TLD1117LV12 trades automotive reliability and ultra-low quiescent current for higher output current and lower unit cost in non-automotive designs.

FAQ
What is the maximum input voltage rating for the NCV8715MX12TBG?
The NCV8715MX12TBG has an absolute maximum input voltage rating of 24 V, with recommended operating range from 2.5 V to 24 V. Operation above 24 V risks permanent damage. The device maintains regulation down to 2.5 V input, making it suitable for cold-crank conditions in 12 V automotive systems where battery voltage may dip to 6.5 V.
Does the NCV8715MX12TBG require an external resistor network to set output voltage?
No, the NCV8715MX12TBG is a fixed-output LDO with factory-trimmed 1.2 V regulation. It does not support adjustable output via external resistors. The output voltage is laser-trimmed during manufacturing to maintain ±2% accuracy across load, line, and temperature - eliminating BOM cost and layout complexity associated with feedback networks.
What is the thermal resistance (RJA) of the NCV8715MX12TBG in its XDFN6 package?
The NCV8715MX12TBG in XDFN6 (Case 711AE) has a measured junction-to-air thermal resistance of 260°C/W when mounted on a PCB with a 650 mm² copper heat-spreading area and 1 oz copper thickness. This value assumes optimal thermal pad soldering and is significantly lower than the SC-70 variant (390°C/W), enabling higher power dissipation in compact automotive modules.
Can the NCV8715MX12TBG be used without an output capacitor?
No, the NCV8715MX12TBG requires a minimum 0.47 µF ceramic output capacitor connected between OUT and GND for stability. The device is optimized for X5R/X7R dielectrics and remains stable across 0.47–10 µF; omitting the capacitor causes oscillation and output voltage collapse. Input capacitance (≥0.1 µF) is also mandatory for transient immunity.
Is the NCV8715MX12TBG qualified for automotive safety-critical applications?
Yes, the NCV8715MX12TBG carries AEC-Q100 Grade 1 qualification (−40°C to +125°C ambient), PPAP capability, and NCV prefix denoting automotive-specific process controls and change management. It is deployed in ASIL-B relevant subsystems including infotainment, ADAS cameras, and telematics - though system-level ASIL compliance requires additional functional safety analysis beyond component qualification.
