Product details

Overview

NCV33375D-5.0R2G from onsemi is an automotive-grade, 5.0 V fixed-output, low-dropout linear voltage regulator in SOIC-8 package, delivering up to 300 mA output current with 260 mV dropout at full load, 2% output voltage tolerance over −40 °C to +125 °C, and logic-level ON/OFF control - deployed in engine control units, body electronics, and ADAS power rails where battery life extension and thermal robustness are critical.

For engineers reviewing the NCV33375D-5.0R2G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 qualification, thermal shutdown at 150 °C, quiescent current of 125 µA (ON) / 0.3 µA (OFF), stability with only 0.22 µF output capacitance, and SOIC-8 footprint compatibility for space-constrained automotive PCBs.

Technical Context

The NCV33375D-5.0R2G employs a PNP pass transistor architecture enabling ultra-low dropout and micropower operation. Its internal control block integrates logic-level ON/OFF functionality with defined high/low thresholds (V_CTRL ≥ 2.4 V for ON; ≤ 0.5 V for OFF), while thermal shutdown and current limiting (450 mA typical) operate independently without hysteresis.

Designed for automotive environments, it features AEC-Q100 Grade 1 qualification (−40 °C to +125 °C ambient), Pb-free packaging, and tight line/load regulation (≤10 mV and ≤25 mV respectively). Output noise is specified at 46 µV_RMS (10 Hz–100 kHz, C_L = 200 µF), supporting noise-sensitive analog and MCU subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	5.0 V ±2% over −40 °C to +125 °C - ensures stable MCU core or sensor bias under wide temperature and load variation.
Max Output Current	300 mA - sufficient for powering microcontrollers, CAN transceivers, or small display drivers in automotive modules.
Dropout Voltage	260 mV at 300 mA - enables regulation down to VIN = 5.26 V, extending usable battery range in 12 V systems.
Quiescent Current	125 µA (ON), 0.3 µA (OFF) - minimizes standby drain in always-on vehicle networks (e.g., door modules, telematics).
Ripple Rejection	65 dB at 120 Hz - suppresses alternator ripple and switching noise from upstream DC/DC converters.
Thermal Shutdown	150 °C junction - protects against sustained overload or poor heatsinking without external circuitry.
Package	SOIC-8 (Case 751), Pb-free - standard surface-mount footprint compatible with automated assembly and IPC-compliant reflow profiles.

Pinout & Package

NCV33375D-5.0R2G uses the SOIC-8 (Case 751) package with exposed pad for enhanced thermal performance. Pin assignments follow Style 10 per onsemi mechanical documentation: Pin 1 = GND, Pin 2 = VIN, Pin 3 = VOUT, Pin 4 = GND, Pin 5 = GND, Pin 6 = ON/OFF, Pin 7 = GND, Pin 8 = VIN.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 5, 7	Ground (GND)	Four dedicated ground pins minimize ground impedance and improve PSRR/stability in noisy automotive environments.
2, 8	Input Voltage (VIN)	Dual VIN pins reduce trace resistance and power dissipation; required for 300 mA operation with <260 mV dropout.
3	Regulated Output (VOUT)	5.0 V fixed output; stable with ≥0.22 µF ceramic capacitor - enables compact layout near load ICs.
6	ON/OFF Control	Logic-compatible enable input; pulled high internally - must be actively driven low (≤0.5 V) to disable output and reduce IQ to 0.3 µA.

Key Features

Feature	Design Value
AEC-Q100 Qualified	Grade 1 (−40 °C to +125 °C) - validated for under-hood and cabin applications without derating.
Low Dropout Architecture	25 mV @ 10 mA, 260 mV @ 300 mA - maintains regulation during cold-crank (VIN ≥ 5.26 V) and battery sag.
Ultra-Low Quiescent Current	0.3 µA in OFF mode - extends battery life in parked-state modules (e.g., remote keyless entry receivers).
Stable with Minimal Capacitance	0.22 µF output cap for 5.0 V version - reduces BOM cost and board area vs. traditional LDOs requiring ≥1 µF.
Integrated Protection	Current limit (450 mA typ.) + thermal shutdown (150 °C) - eliminates need for external foldback or thermal sensors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NCV8664CDT50RKG	Higher IQ (35 µA ON), lower dropout (190 mV @ 300 mA), same SOIC-8 package and AEC-Q100 Grade 1 rating.	Better suited for ultra-low-IQ systems where 35 µA ON current is acceptable and tighter dropout is prioritized.	Select when minimizing dropout is more critical than minimizing ON-mode IQ; verify ON/OFF threshold compatibility (2.0 V logic high).
TLV73350PDBVR	Lower IQ (45 µA ON), smaller SOT-23-5 package, non-automotive grade (−40 °C to +125 °C but not AEC-Q100 qualified).	Applicable only in non-safety-critical consumer or industrial designs lacking automotive qualification requirements.	Choose only for cost- or size-sensitive non-automotive designs; avoid where PPAP, AEC-Q100, or thermal robustness are mandatory.

Compared with NCV33375D-5.0R2G, NCV8664CDT50RKG offers superior dropout performance but higher ON-mode quiescent current, while TLV73350PDBVR provides smaller footprint and lower IQ but lacks AEC-Q100 validation - making NCV33375D-5.0R2G the optimal balance of automotive compliance, thermal resilience, and micropower operation.

FAQ

What is the maximum input voltage rating for NCV33375D-5.0R2G?

The NCV33375D-5.0R2G has a maximum input voltage rating of 13 V DC. This allows safe operation across the full automotive battery range, including load-dump transients up to 13 V when used with appropriate external clamping. Exceeding this voltage may damage the internal PNP pass transistor and protection circuitry.

Does NCV33375D-5.0R2G require an external output capacitor, and what value is recommended?

Yes, NCV33375D-5.0R2G requires an external output capacitor for stability. For the 5.0 V version, a minimum of 0.22 µF ceramic capacitor is specified. Larger values (e.g., 1.0 µF) further improve transient response and noise suppression. The capacitor must be placed as close as possible to Pins 3 (VOUT) and 1/4/5/7 (GND) to maintain loop stability.

How does the ON/OFF control pin function on NCV33375D-5.0R2G?

The ON/OFF pin (Pin 6) enables logic-level control: applying ≥2.4 V turns the regulator ON; pulling ≤0.5 V disables the output and reduces quiescent current to 0.3 µA. The pin must never be left floating - tie to VIN via a pull-up resistor or drive actively. Internal weak pull-up is not present.

Is NCV33375D-5.0R2G thermally protected, and how does it behave during overtemperature events?

Yes, NCV33375D-5.0R2G includes an internal thermal shutdown circuit that activates at ~150 °C junction temperature. It has no hysteresis: output disables when TJ exceeds 150 °C and re-enables once TJ falls below threshold, potentially causing oscillation if heat removal is insufficient. Proper PCB copper area (per Figure 26) is essential for sustained 300 mA operation.

What is the output voltage tolerance of NCV33375D-5.0R2G over temperature and load?

The NCV33375D-5.0R2G guarantees ±2% output voltage tolerance over the full operating junction temperature range (−40 °C to +125 °C) and load current range (0–250 mA). At 25 °C and 0–100 mA, typical tolerance is tighter (±1%), but system design must rely on the worst-case ±2% specification for robustness.
