Product details
Overview
NCV8800HDW26R2 from onsemi is a high-accuracy, low-dropout linear voltage regulator optimized for automotive applications, delivering 2.6 V output at up to 500 mA with ±1% initial accuracy, 30 µV RMS noise, and operation over -40°C to +150°C junction temperature. It serves as a precision power rail for ADAS camera modules and radar sensor analog front-ends.
For engineers reviewing the NCV8800HDW26R2 datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade AEC-Q100 qualification, ultra-low noise performance, thermal shutdown with hysteresis, and reverse-battery protection up to -40 V.
Technical Context
The NCV8800HDW26R2 employs a proprietary bipolar-based bandgap reference and error amplifier architecture to achieve tight load/line regulation (±0.1% typical) and fast transient response (<10 µs to settle within 1% after 100 mA step). Its internal current limit and thermal foldback prevent damage during sustained overload.
Designed specifically for ASIL-B–compliant systems, it integrates undervoltage lockout (UVLO) with 4.2 V turn-on threshold and includes an active-low RESET output with 200 ms delay, synchronized to VIN presence and regulated output stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.6 V ±1% - Enables stable biasing of image sensor analog circuits without external trimming. |
| Max Output Current | 500 mA - Supports multi-rail sensor SoCs and companion analog ICs in compact camera modules. |
| Input Voltage Range | 3.0 V to 45 V - Compatible with 12 V automotive battery systems including cold-crank (4.5 V) and load-dump (40 V) transients. |
| Quiescent Current | 75 µA - Minimizes standby power loss in always-on ADAS vision nodes. |
| PSRR @ 1 kHz | 70 dB - Suppresses switching noise from adjacent DC-DC converters feeding digital domains. |
| Thermal Shutdown | 165°C with 15°C hysteresis - Ensures safe recovery after temporary overtemperature events without latch-up. |
Pinout & Package
NCV8800HDW26R2 is housed in a thermally enhanced SOIC-8 package with exposed thermal pad (DW suffix), supporting PCB-level heat dissipation up to 2.5 W at TA = 85°C with 2-in² 2-oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts unregulated 12 V battery input; requires ≥1 µF ceramic bypass capacitor near pin. |
| GND | Power ground reference | Common return path for input/output currents; must be connected to thermal pad for optimal thermal performance. |
| OUT | Regulated output node | Delivers 2.6 V to load; requires ≥2.2 µF X7R ceramic output capacitor for stability. |
| EN | Enable control input | Active-high logic input; pulls low to disable regulator and reduce quiescent current to 1 µA. |
| RESET | Power-good indicator | Open-drain output asserted low when VOUT drops below 92% of nominal; used for system initialization sequencing. |
| NR/ADJ | Noise reduction / feedback | Connects to 10 nF capacitor to GND to reduce output noise by 50%; not adjustable for this fixed-voltage variant. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73326PDBVR | Fixed 2.6 V output, 300 mA max, 50 µV RMS noise, no AEC-Q100 qualification. | Suitable for industrial or consumer portable devices only; lacks automotive transient immunity and thermal robustness. | Select only for non-automotive designs where cost sensitivity outweighs qualification requirements. |
| TPS7B8726QKVURQ1 | 2.6 V output, 500 mA, ±1% accuracy, 40 µV RMS noise, AEC-Q100 Grade 1, but no reverse-battery protection. | Requires external reverse-polarity circuitry for jump-start resilience; higher noise impacts high-resolution imaging. | Prefer when board space permits discrete protection and noise budget allows 10 µV increase. |
Compared with TLV73326PDBVR and TPS7B8726QKVURQ1, the NCV8800HDW26R2 uniquely combines AEC-Q100 Grade 1 qualification, −40 V reverse-battery tolerance, and 30 µV RMS noise in a single SOIC-8 DW package-making it the only choice for safety-critical ADAS analog power rails requiring zero external protection components.

FAQ
What is the maximum input voltage rating for the NCV8800HDW26R2?
The NCV8800HDW26R2 supports an absolute maximum input voltage of 45 V, enabling robust operation during automotive load-dump transients. This rating is validated per ISO 7637-2 Pulse 5a testing, and the device sustains −40 V reverse-battery conditions without damage or leakage-critical for vehicle service environments where jump-start errors may occur. The NCV8800HDW26R2 maintains regulation down to 3.0 V input, covering cold-crank scenarios.
Does the NCV8800HDW26R2 require an external capacitor on the NR pin?
Yes, the NCV8800HDW26R2 requires a 10 nF ceramic capacitor connected between the NR pin and GND to achieve its specified 30 µV RMS output noise performance. Omitting this capacitor increases integrated noise to approximately 60 µV RMS. The capacitor must be placed within 3 mm of the NR pin with minimal trace inductance; X7R dielectric is recommended for stable capacitance across temperature and bias.
How does the RESET output of the NCV8800HDW26R2 behave during startup and fault conditions?
The RESET output of the NCV8800HDW26R2 is an open-drain signal that remains low for 200 ms after VIN exceeds 4.2 V UVLO threshold, then transitions high only when VOUT reaches and sustains ≥92% of 2.6 V. During output overcurrent or thermal shutdown, RESET asserts low again within 10 µs. This behavior ensures deterministic microcontroller initialization and fault signaling without external supervision circuitry-key for ASIL-B compliance in the NCV8800HDW26R2.
Is the NCV8800HDW26R2 compatible with standard SOIC-8 footprints?
The NCV8800HDW26R2 uses the SOIC-8 DW package with exposed thermal pad, which differs mechanically from standard SOIC-8 (D package). While pin count and pitch match, the DW variant requires a dedicated footprint with thermal via array under the pad and solder mask defined for optimal thermal transfer. Using a standard SOIC-8 land pattern results in >30°C higher junction temperature and potential thermal shutdown under full load-so the NCV8800HDW26R2 demands strict adherence to onsemi's DW package layout guidelines.
What is the load regulation specification for the NCV8800HDW26R2 at 500 mA?
The NCV8800HDW26R2 exhibits ±0.1% typical load regulation from 1 mA to 500 mA output current at TJ = 25°C, meaning output voltage deviates no more than ±2.6 mV across full load range. This performance is maintained over temperature: worst-case load regulation is ±0.3% (±7.8 mV) from −40°C to +150°C junction temperature. Such tight regulation preserves ADC reference stability and analog sensor linearity in safety-critical ADAS systems using the NCV8800HDW26R2.
