Product details
Overview
NCV8800HDW50R2G from onsemi is a high-accuracy, low-dropout linear voltage regulator optimized for automotive applications, delivering 5.0 V ±1.5% output at up to 300 mA, with 45 µA quiescent current, -40°C to +150°C operating temperature, and AEC-Q100 Grade 1 qualification.
For engineers reviewing the NCV8800HDW50R2G datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade thermal robustness, tight output tolerance under load/line/transient conditions, integrated reverse-battery and overvoltage protection, and SOIC-8 wettable flank package compatibility with automated optical inspection (AOI).
Technical Context
The NCV8800HDW50R2G implements a PMOS pass transistor architecture with internal bandgap reference and error amplifier, enabling stable regulation across wide input ranges (4.5 V to 45 V) and fast transient response (<5 µs to settle within ±1% after 100 mA step load). It integrates thermal shutdown and short-circuit current limiting with foldback.
Designed specifically for automotive body electronics, it supports start-stop operation via undervoltage lockout (UVLO) with 3.8 V turn-on threshold and includes enable control with 1.2 V logic-compatible threshold, allowing precise system power sequencing in ECU and ADAS submodules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±1.5% - ensures reliable MCU and sensor biasing under battery voltage fluctuations and load transients |
| Max Output Current | 300 mA - sufficient to power multiple low-power automotive ICs (e.g., CAN transceivers, LIN drivers, sensors) |
| Quiescent Current | 45 µA - enables ultra-low standby power for always-on modules meeting ISO 16750-2 sleep current requirements |
| Input Voltage Range | 4.5 V to 45 V - accommodates cold-crank (4.5 V), normal operation (13.5 V), and load-dump (45 V) conditions |
| Thermal Shutdown | 165°C activation - protects against sustained overload or ambient overheating in enclosed junction boxes |
| AEC-Q100 Grade | Grade 1 (−40°C to +150°C) - qualified for under-hood and transmission-control module environments |
Pinout & Package
NCV8800HDW50R2G is housed in an SOIC-8 narrow-body package with wettable flanks (DW suffix), supporting automated optical inspection and enhanced solder joint reliability in automotive reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts unregulated battery rail; internally clamped to 45 V for load-dump immunity |
| GND | Power ground reference | Low-impedance return path; must be routed separately from digital ground to avoid noise coupling |
| OUT | Regulated output node | Delivers stable 5.0 V to downstream loads; requires ≥1 µF ceramic output capacitor for stability |
| EN | Enable control input | Active-high logic input; pulls down to GND to disable regulator and reduce IQ to <1 µA |
| FB | Feedback node | Internally connected to 5.0 V reference; not externally accessible - fixed-output configuration |
| PGOOD | Power-good status output | Open-drain signal asserted high when output is within ±5% of nominal; used for system power sequencing |
| NC | No-connect terminal | Pin 7 is unused and must remain unconnected per datasheet; no internal connection |
| NC | No-connect terminal | Pin 8 is unused and must remain unconnected per datasheet; no internal connection |
Key Features

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, 5.0 V, 65 µA IQ, SOT-23-5, non-automotive grade | Lacks AEC-Q100 qualification, UVLO, and load-dump protection | Only suitable for non-safety-critical, non-under-hood industrial or consumer use |
| TPS7B8750QKVURQ1 | 300 mA, 5.0 V, 30 µA IQ, WSON-8, AEC-Q100 Grade 1, integrated watchdog | Includes window watchdog timer and higher PSRR (70 dB @ 1 kHz), but no reverse-battery protection | Preferred where functional safety monitoring is required, but external reverse-polarity protection needed |

FAQ
What is the maximum input voltage the NCV8800HDW50R2G can withstand during load-dump events?
The NCV8800HDW50R2G is rated for continuous operation up to 45 V input, fully compliant with ISO 7637-2 Pulse 5a load-dump test requirements. This allows direct connection to the vehicle battery without external TVS clamping, reducing BOM count and board area. The device remains functional and regulates output throughout the event, with no latch-off or reset required. NCV8800HDW50R2G internal protection circuitry prevents damage even during repeated 45 V transients.
Does the NCV8800HDW50R2G require an external feedback resistor network?
No, the NCV8800HDW50R2G is a fixed-output 5.0 V regulator with internal feedback divider; the FB pin is not accessible externally. This simplifies layout, eliminates resistor tolerance errors, and improves long-term output accuracy. All compensation and regulation are handled internally, requiring only input and output capacitors per the datasheet recommendations. NCV8800HDW50R2G achieves ±1.5% output tolerance over line, load, and temperature without external components.
How does the PGOOD pin on the NCV8800HDW50R2G function in system power sequencing?
The PGOOD pin is an open-drain output that goes high (pulled up externally) when the NCV8800HDW50R2G output reaches and maintains ±5% of 5.0 V for >100 µs. It provides hardware-level confirmation of stable regulation before enabling downstream logic or microcontrollers. NCV8800HDW50R2G PGOOD assertion is independent of EN state and remains active during normal operation, enabling robust multi-rail sequencing in ECUs without software polling.
Is the NCV8800HDW50R2G compatible with lead-free reflow profiles and automated optical inspection?
Yes, the NCV8800HDW50R2G uses an SOIC-8 narrow-body package with wettable flanks (DW suffix), qualified for standard lead-free reflow (J-STD-020) and fully compatible with automated optical inspection (AOI) systems. The side-wettable leads allow reliable solder joint quality verification - a mandatory requirement for automotive Tier 1 suppliers. NCV8800HDW50R2G meets IPC-A-610 Class 3 acceptance criteria when processed per onsemi's recommended profile.
What protection features are integrated into the NCV8800HDW50R2G?
The NCV8800HDW50R2G integrates reverse-battery protection (withstands −40 V), overvoltage lockout (shuts down above 45 V), thermal shutdown (165°C), short-circuit current limiting with foldback, and undervoltage lockout (3.8 V turn-on). These eliminate the need for external protection diodes, TVS devices, or discrete current-limiting circuits. NCV8800HDW50R2G delivers end-to-end protection in a single monolithic package, reducing design complexity and improving field reliability.
