Product details
Overview
NCV8504PW50R2G from onsemi is a 500 mA low-dropout (LDO) linear regulator with fixed 5.0 V output, ±2% output voltage accuracy, thermal shutdown and current limit protection, and 60 µA quiescent current - designed for automotive body electronics and infotainment power rails.
For engineers reviewing the NCV8504PW50R2G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 Grade 1 qualification, dropout voltage of 350 mV at 500 mA, PSRR of 70 dB at 1 kHz, reverse battery protection, and operation across –40 °C to +150 °C junction temperature range.
Technical Context
The NCV8504PW50R2G integrates a PNP pass transistor with internal biasing and feedback control to maintain stable 5.0 V regulation under load transients up to 100 mA/µs. It features integrated thermal foldback and short-circuit current limiting that dynamically reduce output current during overtemperature or overload conditions.
Designed specifically for automotive environments, the device includes reverse-battery protection down to –40 V, undervoltage lockout (UVLO) with 4.2 V turn-on threshold, and input transient tolerance compliant with ISO 7637-2 Pulse 1/2a/3a/5a requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% - ensures compatibility with 5 V microcontrollers, CAN transceivers, and sensor interfaces without external resistors. |
| Max Output Current | 500 mA - supports multiple downstream ICs including MCU cores, I/O peripherals, and analog front-ends in compact ECUs. |
| Dropout Voltage | 350 mV at 500 mA - enables stable regulation even when input drops to 5.35 V, critical for cold-crank automotive operation. |
| Quiescent Current | 60 µA - minimizes standby power loss in always-on domains such as body control modules and gateway wake-up circuits. |
| PSRR | 70 dB at 1 kHz - suppresses ripple from upstream switching converters, preserving signal integrity in ADC references and audio subsystems. |
| Operating Temp | –40 °C to +150 °C - qualified per AEC-Q100 Grade 1, enabling placement near heat sources like power inverters or engine compartments. |
| Protection | Thermal shutdown, current limit, reverse-battery (–40 V), UVLO - eliminates need for external protection circuitry in harsh automotive environments. |
Pinout & Package
NCV8504PW50R2G is housed in a thermally enhanced SOIC-8 (SOIC-W) package with exposed thermal pad, optimized for PCB heat dissipation in high-ambient automotive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts 5.5 V to 45 V DC input; reverse-battery protected to –40 V. |
| GND | Power ground reference | Common return path for load current and internal bias; connects to thermal pad for heat transfer. |
| OUT | Regulated output terminal | Delivers stable 5.0 V to loads; requires ≥2.2 µF ceramic output capacitor for stability. |
| EN | Enable control input | Active-high logic input; pulls internal pass element off when low, reducing quiescent current to <1 µA. |
| BP | Bias power supply | Internal bias rail derived from IN; decoupled externally with 0.1 µF capacitor to GND. |
| NC | No-connect terminal | Internally unused; must be left floating or tied to GND per layout guidelines. |
| NC | No-connect terminal | Internally unused; must be left floating or tied to GND per layout guidelines. |
| EP | Exposed thermal pad | Electrically connected to GND; soldered to PCB copper pour for thermal conduction and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 | Qualified for automotive use from –40 °C to +150 °C ambient, enabling deployment in engine bay and transmission control units. |
| Reverse-battery protection | Withstands –40 V input without damage or latch-up, eliminating need for external series diode in battery-connected systems. |
| Low quiescent current | 60 µA typical in active mode and <1 µA in shutdown - extends battery life in always-on vehicle networks. |
| High PSRR at 1 kHz | 70 dB attenuation of switching noise from upstream DC-DC converters - improves ADC resolution and RF receiver sensitivity. |
| Thermal foldback | Reduces output current progressively above 140 °C junction temperature - prevents thermal runaway during sustained overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA max output, 25 µA IQ, no reverse-battery protection, not AEC-Q100 qualified | Suitable only for non-automotive industrial or consumer applications with benign supply conditions | Select only if automotive qualification, reverse-battery tolerance, or >300 mA load is not required |
| TPS7B8150QDGNRQ1 | 500 mA, AEC-Q100 Grade 1, 25 µA IQ, but lacks reverse-battery protection and has higher dropout (450 mV @ 500 mA) | Requires external reverse-polarity protection diode in battery-connected designs | Prefer when ultra-low IQ is prioritized and reverse-battery stress is mitigated externally |
Compared with TLV73350PDBVR and TPS7B8150QDGNRQ1, the NCV8504PW50R2G uniquely combines AEC-Q100 Grade 1 rating, integrated –40 V reverse-battery protection, and 350 mV dropout - making it the only choice for direct battery-connected automotive LDO applications demanding full ISO 7637-2 compliance without external components.

FAQ
What is the maximum input voltage rating for the NCV8504PW50R2G?
The NCV8504PW50R2G supports an absolute maximum input voltage of 45 V and includes reverse-battery protection down to –40 V. This allows direct connection to automotive 12 V battery rails while surviving jump-starts, load-dump transients, and reverse-polarity connections without external protection components. The device remains functional across its full operating range from 5.5 V to 45 V input.
Does the NCV8504PW50R2G require an external output capacitor?
Yes, the NCV8504PW50R2G requires a minimum 2.2 µF ceramic output capacitor with X5R or X7R dielectric placed close to the OUT and GND pins. This capacitor ensures loop stability, reduces output impedance at high frequencies, and improves transient response to load steps. Larger values (e.g., 10 µF) further enhance ripple suppression and step-load recovery.
Is the NCV8504PW50R2G pin-compatible with other onsemi LDOs in SOIC-8 packages?
No, the NCV8504PW50R2G has a unique pin assignment including dedicated BP (bias power) and two NC pins, differing from standard 5-pin or 6-pin SOIC LDO layouts. Its pinout is not interchangeable with devices like NCV8775 or NCV8674. Layout must follow the official onsemi SOIC-W footprint and thermal pad soldering guidelines to ensure thermal performance and reliability.
What is the thermal shutdown threshold of the NCV8504PW50R2G?
The NCV8504PW50R2G activates thermal shutdown at approximately 165 °C junction temperature and remains latched off until junction temperature falls below ~145 °C. During rising temperature, thermal foldback begins around 140 °C to gradually reduce output current and avoid abrupt shutdown - supporting graceful degradation in sustained overload scenarios common in automotive ECU enclosures.
Can the NCV8504PW50R2G be used in non-automotive applications?
Yes, the NCV8504PW50R2G can be used in industrial or medical applications requiring high-reliability 5 V regulation, wide input range, and robust protection features. However, its AEC-Q100 qualification, automotive-grade screening, and extended temperature capability come at a cost premium versus commercial-grade LDOs. Use is justified where long-term supply assurance, thermal resilience, or reverse-polarity tolerance adds system-level value beyond basic regulation.
