Product details
Overview
NCV866710D250R2G from onsemi is a high-accuracy, low-quiescent-current automotive-grade LDO voltage regulator delivering 100 mA output current with ±2% output voltage accuracy at 10 V, 300 mV dropout at 100 mA, and -40°C to +150°C operating temperature range; used in engine control units (ECUs) for powering microcontrollers and sensors.
For engineers reviewing the NCV866710D250R2G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 Grade 1 qualification, thermal shutdown protection, reverse battery protection, and ultra-low 22 µA quiescent current in standby mode.
Technical Context
The NCV866710D250R2G integrates a precision bandgap reference, error amplifier, and PNP pass transistor in a single monolithic IC. It operates with input voltages from 3.5 V to 45 V and maintains regulation down to 300 mV dropout at full load, enabling stable operation during cold-crank conditions in 12 V automotive systems.
Its internal circuitry includes undervoltage lockout (UVLO) at 2.7 V, overtemperature shutdown with hysteresis, and short-circuit current limiting. The device supports fixed 10 V output without external feedback components and features integrated reverse-battery protection up to −45 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 10.0 V ±2% - ensures precise supply for ADC references and CAN transceivers. |
| Max Output Current | 100 mA - sufficient for powering small MCUs, sensors, and interface ICs in body control modules. |
| Quiescent Current | 22 µA (typ) - enables always-on functionality in vehicle security and telematics without excessive battery drain. |
| Dropout Voltage | 300 mV @ 100 mA - sustains regulation during 12 V system cold-crank dips to 6 V. |
| Operating Temp Range | −40°C to +150°C - qualified for under-hood placement per AEC-Q100 Grade 1. |
| Protection Features | Thermal shutdown, reverse-battery (−45 V), short-circuit, UVLO - eliminates need for external protection circuitry. |
Pinout & Package
NCV866710D250R2G is housed in a thermally enhanced SOIC-8 package (SOIC-8 NB, 3.9 mm × 4.9 mm, 1.27 mm pitch) with exposed thermal pad for improved heat dissipation in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 3.5–45 V DC; connects directly to battery rail with minimal external filtering. |
| GND | Ground reference | Common return path for load current and internal bias; tied to thermal pad for thermal conduction. |
| OUT | Regulated output | Delivers stable 10 V to downstream loads; requires ≥1 µF ceramic output capacitor for stability. |
| EN | Enable control input | Active-high logic input; pulls low to disable regulator and reduce IQ to <1 µA. |
| SENSE | Voltage sense feedback | Internally connected to fixed 10 V reference; no external resistor network required. |
| NC | No connect | Two pins (pins 2 and 7) are internally unconnected; must remain floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +150°C ambient operation-enables direct integration into powertrain and chassis ECUs. |
| Reverse-battery protection | Withstands −45 V applied to IN while maintaining zero output leakage-eliminates need for external series diode. |
| Ultra-low quiescent current | 22 µA typical in active mode and <1 µA in shutdown-supports ISO 8859-3-compliant sleep modes. |
| Integrated thermal shutdown | Hysteretic protection triggers at +175°C junction and resumes after cooling to +155°C-prevents thermal runaway without external monitoring. |
| Cold-crank capable | Maintains regulation with VIN ≥ VOUT + 300 mV down to 6 V input-ensures MCU boot during engine start. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73310PDBVR | 300 mA output, 25 µA IQ, no reverse-battery protection, not AEC-Q100 qualified | Suitable for non-automotive industrial or consumer applications only | Select only if automotive qualification and reverse-battery immunity are not required. |
| TPS7B6750QDDARQ1 | 500 mA output, 28 µA IQ, integrated watchdog timer, AEC-Q100 Grade 1 | Higher current capability and added functional safety features for ASIL-B systems | Prefer when higher load current or diagnostic coverage is needed beyond basic regulation. |
Compared with TLV73310PDBVR and TPS7B6750QDDARQ1, the NCV866710D250R2G offers optimal balance of 100 mA drive, ultra-low 22 µA quiescent current, reverse-battery tolerance, and AEC-Q100 Grade 1 compliance-making it ideal for cost-sensitive, thermally constrained automotive modules where reliability under harsh conditions is critical.

FAQ
What is the maximum input voltage rating for the NCV866710D250R2G?
The NCV866710D250R2G supports an absolute maximum input voltage of 45 V. This rating allows safe operation during load-dump transients common in 12 V automotive systems, where voltage spikes up to 40 V can occur. The device remains functional and protected within this limit without requiring external clamping components.
Does the NCV866710D250R2G require an external output capacitor?
Yes, the NCV866710D250R2G requires a minimum 1 µF ceramic output capacitor placed close to the OUT and GND pins for stability and transient response. onsemi recommends X7R or X5R dielectrics with ≤100 mΩ ESR. Omitting or undersizing this capacitor may cause oscillation or poor line/load regulation in the NCV866710D250R2G.
Is the NCV866710D250R2G pin-compatible with other devices in the NCV8667 family?
Yes, the NCV866710D250R2G shares identical SOIC-8 pinout and footprint with all fixed-output variants in the NCV8667 family (e.g., NCV866750D250R2G, NCV866733D250R2G). Only the SENSE and OUT pins differ in internal connection-no PCB redesign is needed when changing output voltage variants.
What protection features are integrated into the NCV866710D250R2G?
The NCV866710D250R2G integrates thermal shutdown with hysteresis, reverse-battery protection up to −45 V, short-circuit current limiting, and undervoltage lockout at 2.7 V. These features eliminate the need for discrete protection components, reducing BOM count and improving system-level reliability in automotive applications.
Can the NCV866710D250R2G be used in non-automotive applications?
Yes, the NCV866710D250R2G can be used in industrial or commercial applications requiring high-reliability 10 V regulation, but its AEC-Q100 qualification, extended temperature range, and automotive-specific protections (e.g., reverse-battery tolerance) provide design margin beyond typical industrial specs. Its 22 µA quiescent current also benefits battery-powered equipment.
