Product details
Overview
NCV87706DS50R4G from onsemi is an automotive-grade 600 mA low-dropout linear regulator with 5.0 V fixed output, ±2% accuracy, 25 µA quiescent current, and integrated reset function for microcontroller supervision in engine control units and body control modules.
For engineers reviewing the NCV87706DS50R4G datasheet, pinout, applications, or equivalent options, key selection criteria include automotive AEC-Q100 Grade 1 qualification, wide input voltage range (4.5 V to 40 V), reverse battery protection, thermal shutdown, and reset timeout programmability via external capacitor.
Technical Context
The NCV87706DS50R4G integrates a precision bandgap reference, error amplifier, pass transistor, and reset comparator with adjustable delay. It operates over –40 °C to +150 °C ambient and supports load currents up to 600 mA with dropout as low as 270 mV at full load.
Its reset function monitors VOUT and asserts an open-drain RESET signal when output falls below 92.5% of nominal (4.625 V), with timeout delay set by an external capacitor (1.0 ms to 10 s range). Reverse polarity protection enables operation down to –42 V input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% - ensures stable MCU core/logic supply under battery transients. |
| Max Output Current | 600 mA - supports multiple downstream logic ICs or small microcontrollers without external boost. |
| Quiescent Current | 25 µA typical - enables always-on monitoring in vehicle sleep modes without excessive battery drain. |
| Input Voltage Range | 4.5 V to 40 V - accommodates cold-crank (4.5 V) and load-dump (40 V) conditions per ISO 7637-2. |
| Reset Threshold | 92.5% of VOUT (4.625 V) - guarantees reliable MCU reset before logic corruption occurs. |
| Reset Timeout Range | 1.0 ms to 10 s via external CRT - allows precise alignment with system boot sequence timing. |
| AEC-Q100 Grade | Grade 1 (–40 °C to +125 °C junction) - qualified for under-hood automotive applications. |
Pinout & Package
NCV87706DS50R4G is housed in a thermally enhanced SOIC-8 package (suffix "DS") with exposed thermal pad, supporting high-power dissipation in compact automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts 4.5–40 V DC; includes reverse-battery protection diode internally. |
| GND | Power ground reference | Common return path for regulator and reset circuitry; connects to thermal pad. |
| OUT | Regulated 5.0 V output | Supplies downstream loads; requires ≥10 µF ceramic output capacitance for stability. |
| RESET | Open-drain reset output | Active-low signal asserted when VOUT < 4.625 V; requires external pull-up resistor. |
| RT | Reset timeout timing node | Connects external capacitor to set reset assertion duration (1 ms–10 s). |
| EN | Enable input (active-high) | Pull high ≥2.0 V to enable regulation; tie to IN for always-on operation. |
| NC | No connect | Pin 7 is unused and must remain unconnected per datasheet. |
| EPAD | Thermal pad (exposed) | Must be soldered to PCB copper pour for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Reset Supervisor | Eliminates need for discrete reset IC; reduces BOM count and board area in ECU designs. |
| Reverse Battery Protection | Withstands –42 V input without external components-critical for service/maintenance scenarios. |
| Low Quiescent Current | 25 µA enables >1-year battery life in always-on vehicle modules during extended parking. |
| Thermal Shutdown with Hysteresis | Shuts down at 165 °C and restarts at 145 °C-prevents latch-up during transient overload. |
| Load Dump Protection | Survives 40 V/100 ms pulses per ISO 7637-2 Pulse 5a-no external TVS required in many cases. |
Applications

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 max output, no reset function, non-automotive grade (no AEC-Q100), 50 µA IQ. | Suitable only for non-safety-critical infotainment peripherals-not for ECU/BCM. | Select only for cost-sensitive, non-automotive designs where reset supervision is handled externally. |
| TPS7B8750QKVURQ1 | 750 mA output, integrated watchdog timer, higher IQ (35 µA), same AEC-Q100 Grade 1. | Supports more complex safety protocols (e.g., ASIL-C) but requires additional configuration pins. | Prefer when system-level functional safety demands watchdog capability beyond basic reset. |
Compared with NCV87706DS50R4G, TLV73350PDBVR lacks automotive qualification and reset functionality-limiting use to non-critical subsystems-while TPS7B8750QKVURQ1 adds watchdog features at higher IQ and complexity, making it suitable for higher-ASIL domains where NCV87706DS50R4G's simpler reset-only supervision suffices.

FAQ
What is the maximum input voltage rating for the NCV87706DS50R4G?
The NCV87706DS50R4G supports a maximum input voltage of 40 V, compliant with ISO 7637-2 Load Dump Pulse 5a testing. This rating enables robust operation during vehicle load dump events without requiring external clamping components in most implementations. The device also withstands reverse battery conditions down to –42 V, eliminating the need for external reverse-polarity protection diodes in standard automotive harness configurations.
Does the NCV87706DS50R4G require an external capacitor for reset timeout configuration?
Yes, the NCV87706DS50R4G uses an external capacitor connected to the RT pin to set reset timeout duration. Capacitor values from 1 nF to 100 nF yield timeouts between 1.0 ms and 10 s, respectively. This programmability allows precise alignment with MCU boot timing requirements. No internal timing element exists-the RT capacitor directly determines the reset assertion window after power-up or brownout recovery.
Is the NCV87706DS50R4G qualified for automotive applications?
Yes, the NCV87706DS50R4G is AEC-Q100 qualified to Grade 1 (–40 °C to +125 °C junction temperature), making it suitable for under-hood and cabin-mounted automotive control units. It meets automotive-specific stress tests including temperature cycling, humidity bias, and mechanical shock. Its design incorporates features essential for automotive use: reverse battery protection, load dump survival, and integrated reset supervision-all verified per AEC-Q100 test plans.
What is the quiescent current of the NCV87706DS50R4G in enabled state?
The NCV87706DS50R4G draws 25 µA typical quiescent current when enabled and regulating, with a maximum of 45 µA over temperature and process variation. This ultra-low IQ enables compliance with automotive "parking mode" current budgets, supporting >1-year battery hold-up time in always-on modules such as telematics or alarm controllers without risking deep discharge.
Can the NCV87706DS50R4G be used without connecting the EN pin?
Yes, the NCV87706DS50R4G can operate without external EN control by tying the EN pin directly to the IN supply. In this configuration, the device remains enabled whenever input voltage exceeds the turn-on threshold (~2.0 V). This simplifies design for always-on applications like engine control modules, eliminating the need for external enable sequencing logic while retaining full reset supervision functionality.
