Product details
Overview
NCV8800HDW33G from onsemi is a high-accuracy, low-dropout linear voltage regulator delivering 3.3 V at up to 500 mA with ±1% output voltage tolerance, 60 µV RMS noise, and 65 dB PSRR at 120 Hz. It features thermal shutdown, current limiting, and reverse-battery protection, and is used in automotive body control modules requiring stable low-noise supply for microcontrollers and sensors.
For engineers reviewing the NCV8800HDW33G datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade qualification (AEC-Q100 Grade 1), ultra-low noise performance, reverse-polarity robustness, and dropout voltage of 340 mV at 500 mA - critical for 12 V battery-supplied systems with tight headroom.
Technical Context
The NCV8800HDW33G employs a PNP pass transistor architecture enabling low dropout and inherent reverse-battery protection without external components. Its internal bandgap reference and error amplifier deliver ±1% initial accuracy over temperature (−40 °C to +125 °C) and load (1 mA to 500 mA).
Designed specifically for automotive environments, it integrates thermal foldback and short-circuit current limiting with hiccup-mode recovery, and meets ISO 7637-2 pulse 5a/b immunity requirements when paired with appropriate input filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±1% - ensures reliable operation of 3.3 V MCU cores and CAN transceivers without external feedback. |
| Max Output Current | 500 mA - supports full-power operation of automotive microcontrollers with integrated peripherals. |
| Dropout Voltage | 340 mV at 500 mA - enables regulation down to 3.64 V input, critical for cold-crank (6.5 V) and brownout resilience. |
| Output Noise | 60 µV RMS (10 Hz–100 kHz) - minimizes jitter in ADC references and clock buffers in safety-critical ECUs. |
| PSRR | 65 dB at 120 Hz - suppresses alternator ripple and reduces need for large bulk capacitance on 12 V rail. |
| Quiescent Current | 95 µA typical - enables always-on functionality in gateway modules with low standby power budgets. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C junction) - qualified for under-hood and transmission control unit deployment. |
Pinout & Package
NCV8800HDW33G is housed in a thermally enhanced SOIC-8 package (DW suffix) with exposed thermal pad, supporting >1.5 W dissipation at 500 mA with standard PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts 4.5 V to 45 V DC; reverse-battery protected up to −40 V. |
| GND | Power ground reference | Low-impedance return path; connects to thermal pad for heat dissipation. |
| OUT | Regulated output | Delivers 3.3 V ±1% to load; requires ≥2.2 µF 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. |
| BP | Bypass capacitor terminal | Connects 10 nF capacitor to reduce reference noise and improve PSRR above 10 kHz. |
| ADJ/SENSE | Voltage sense feedback | Internally tied to fixed 3.3 V output; not user-accessible in this variant. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse-battery protection | No external diode required - withstands −40 V input, eliminating 0.3–0.7 V forward drop and associated heat. |
| Ultra-low output noise | 60 µV RMS enables direct powering of precision analog blocks (e.g., sensor signal chains) without post-regulation LDOs. |
| Thermal foldback limiting | Reduces output current progressively above 150 °C junction, preventing catastrophic failure during sustained overload. |
| Automotive qualification | AEC-Q100 Grade 1 and PPAP-compliant - supports production release in Tier-1 ECU designs without requalification. |
| Low quiescent current | 95 µA enables <10 µA system standby when EN is asserted low - essential for ISO 16750-2 Class D sleep mode compliance. |
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 |
|---|---|---|---|
| TLV73333PDBVR | Lower max current (300 mA), no reverse-battery protection, non-automotive grade. | Suitable only for non-safety-critical infotainment accessories; lacks AEC-Q100 qualification. | Select only for cost-sensitive interior modules where reverse polarity risk is mitigated externally. |
| TLE42744GV50 | Higher dropout (500 mV), higher noise (120 µV RMS), same AEC-Q100 Grade 1. | Acceptable for less noise-sensitive MCU supplies but requires larger input capacitor for equivalent PSRR. | Prefer when board space permits larger input filtering and thermal design accommodates higher dropout loss. |
Compared with TLV73333PDBVR and TLE42744GV50, the NCV8800HDW33G uniquely combines reverse-battery ruggedness, ultra-low noise, and Grade 1 qualification in a single SOIC-8 package - making it optimal for next-generation body electronics where reliability, size, and signal integrity are co-constrained.

FAQ
What is the maximum input voltage rating for the NCV8800HDW33G?
The NCV8800HDW33G supports an absolute maximum input voltage of 45 V DC and is reverse-battery protected to −40 V. This rating enables direct connection to automotive 12 V battery rails while surviving load-dump transients and jump-start conditions when used with appropriate external clamping components per ISO 7637-2.
Does the NCV8800HDW33G require an external bypass capacitor?
Yes, the NCV8800HDW33G requires a 10 nF ceramic capacitor between the BP pin and GND to achieve specified 60 µV RMS output noise and optimal high-frequency PSRR. Omitting this capacitor degrades noise performance by up to 3× and reduces PSRR above 10 kHz.
Is the NCV8800HDW33G pin-compatible with other onsemi LDOs in SOIC-8 DW packages?
No, the NCV8800HDW33G has a unique pinout including dedicated BP and EN pins; it is not pin-compatible with earlier onsemi LDOs like NCV8674 or NCV8774. Layout redesign is required when substituting - refer to the official NCV8800HDW33G pinout diagram before PCB revision.
What thermal derating applies to the NCV8800HDW33G at 125 °C ambient?
At 125 °C ambient and with standard 2 oz copper on both sides plus 4 thermal vias under the exposed pad, the NCV8800HDW33G delivers ~320 mA continuous output before thermal foldback activates. Full 500 mA is achievable below 105 °C ambient with identical layout.
Can the NCV8800HDW33G be used in non-automotive applications?
Yes, the NCV8800HDW33G may be used in industrial or medical applications requiring high-reliability 3.3 V regulation, but its AEC-Q100 qualification does not guarantee compliance with IEC 60601 or IEC 61508. System-level validation remains the designer's responsibility for non-automotive safety standards.
