Product details
Overview
NCV8800HDW75R2G from onsemi is a high-accuracy, low-dropout linear voltage regulator optimized for automotive applications, delivering 750 mA output current with ±1.5% output voltage tolerance, 200 mV dropout at full load, and operation across –40°C to +150°C junction temperature. It regulates 5.0 V output from input voltages up to 45 V and integrates thermal shutdown, short-circuit protection, and reverse-battery protection.
For engineers reviewing the NCV8800HDW75R2G datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade AEC-Q100 qualification, integrated reverse-battery protection, tight output tolerance over temperature, and support for wide-input automotive battery transients (45 V load dump).
Technical Context
The NCV8800HDW75R2G employs a precision bandgap reference and error amplifier to maintain stable 5.0 V regulation under dynamic load steps and wide input voltage variation. Its internal PNP pass transistor enables low dropout and inherent reverse-polarity immunity without external components.
Designed specifically for automotive body electronics and infotainment power rails, it meets ISO 7637-2 pulse 5a (load dump) and ISO 16750-2 supply voltage transient requirements, and supports enable-controlled sequencing via the EN pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±1.5% - Tight tolerance ensures reliable logic-level compatibility for MCU, CAN transceivers, and sensors. |
| Max Output Current | 750 mA - Sufficient to power multiple automotive subsystems (e.g., camera module + interface IC) from single rail. |
| Dropout Voltage | 200 mV @ 750 mA - Enables regulation down to 5.2 V input, supporting cold-crank operation (6.0 V min). |
| Input Voltage Range | 4.5 V to 45 V - Covers full automotive battery range including load dump transients. |
| Junction Temp Range | –40°C to +150°C - Qualified for under-hood and transmission control module environments. |
| Protection Features | Thermal shutdown, short-circuit, reverse-battery - Eliminates need for external diodes or fuses in harsh environments. |
| AEC-Q100 Grade | Grade 1 - Certified for automotive production use per AEC-Q100 Rev G. |
Pinout & Package
NCV8800HDW75R2G is housed in a thermally enhanced SOIC-8 package (DW suffix), with exposed thermal pad for PCB heat sinking. Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = OUT, Pin 5 = GND, Pin 6 = GND, Pin 7 = GND, Pin 8 = GND - all ground pins are internally bonded to the thermal pad for low-impedance thermal and electrical return.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 4.5–45 V; must be decoupled locally to handle load dump energy. |
| GND (Pins 2,5,6,7,8) | Ground reference and thermal path | Multiple GND pins reduce IR drop and improve thermal dissipation via thermal pad connection. |
| EN (Pin 3) | Enable control input | Active-high logic; pulls low to disable regulator and reduce quiescent current to <1 µA. |
| OUT (Pin 4) | Regulated output | Delivers 5.0 V ±1.5% to downstream loads; requires ≥10 µF ceramic output capacitor for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse-battery protection | Operates safely with –40 V applied to IN - eliminates need for external series diode and associated power loss. |
| Low quiescent current | 45 µA typical in active mode - extends battery life during vehicle sleep modes (e.g., CAN wake-up monitoring). |
| Load dump immunity | Withstands 45 V/100 ms pulses per ISO 7637-2 - enables direct connection to automotive battery without external TVS. |
| Enable-controlled sequencing | EN pin supports controlled power-up/down timing with external microcontroller - critical for multi-rail systems with strict startup order. |
| Thermal foldback | Reduces output current above 145°C junction temp - prevents thermal runaway during sustained overload or poor heatsinking. |
Applications
| ADAS Camera Power Supply | Body Control Module (BCM) |
|---|---|
Use Scenario: Powers image sensor, ISP, and serial interface in rear-view or surround-view cameras mounted externally. IC Role / Device Role / Timing Role: Primary 5 V LDO supplying regulated power to vision processing chain with low noise and high PSRR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA output, no reverse-battery protection, only 125°C max junction temp | Suitable for non-automotive or interior-only modules with lower ambient temps | Select only if system includes external reverse-polarity diode and thermal derating is acceptable. |
| TPS7B8750QKVURQ1 | 500 mA output, integrated watchdog timer, higher 300 mV dropout | Better for safety-critical ASIL-B domains requiring fault reporting | Prefer when functional safety diagnostics (e.g., reset timeout) are required alongside regulation. |
Compared with TLV73350PDBVR and TPS7B8750QKVURQ1, the NCV8800HDW75R2G delivers higher output current, full reverse-battery immunity, and extended temperature capability - making it optimal for under-hood and exterior automotive modules where protection and ruggedness are primary design constraints.

FAQ
What is the maximum input voltage the NCV8800HDW75R2G can withstand during load dump events?
The NCV8800HDW75R2G is rated for 45 V continuous input and is designed to survive ISO 7637-2 Pulse 5a load dump transients (45 V, 100 ms) without external clamping. This capability is verified per AEC-Q100 stress testing and allows direct connection to automotive battery rails in engine compartments and exterior modules.
Does the NCV8800HDW75R2G require an external reverse-polarity protection diode?
No, the NCV8800HDW75R2G integrates reverse-battery protection and operates safely with –40 V applied to the IN pin. This eliminates the need for an external series diode, reducing conduction losses, board space, and thermal overhead - a key differentiator versus standard LDOs like the TLV73350PDBVR.
What is the minimum input voltage required for the NCV8800HDW75R2G to maintain regulation during cold-crank conditions?
The NCV8800HDW75R2G maintains 5.0 V regulation down to an input voltage of 5.2 V (200 mV dropout at 750 mA). This supports automotive cold-crank scenarios where battery voltage may dip to 6.0 V nominal, ensuring uninterrupted power to critical ECUs such as camera modules and sensor interfaces.
How many ground pins does the NCV8800HDW75R2G SOIC-8 package have, and why are they important?
The NCV8800HDW75R2G uses a SOIC-8 package with five dedicated ground pins (Pins 2, 5, 6, 7, and 8), all electrically and thermally connected to the exposed thermal pad. This configuration minimizes ground path impedance, improves thermal resistance by ~25%, and enhances PSRR performance - critical for noise-sensitive automotive imaging and communication circuits.
Is the NCV8800HDW75R2G qualified to AEC-Q100, and which grade does it meet?
Yes, the NCV8800HDW75R2G is fully qualified to AEC-Q100 Rev G and certified as Grade 1, meaning it is tested and guaranteed to operate reliably from –40°C to +125°C ambient (–40°C to +150°C junction). This qualification covers accelerated stress tests including HTOL, TC, UHAST, and ESD, confirming suitability for production automotive applications.
