Product details
Overview
NCV8623MN-33R2G from onsemi is an automotive-grade, ultra-low-noise, low-dropout linear regulator delivering 150 mA output current with a typical dropout voltage of 137 mV at 100 mA and output noise of 25 µVRMS (100 Hz–100 kHz, with 10 nF bypass capacitor). It features logic-level ON/OFF control, thermal shutdown, short-circuit protection, and operates across −40°C to +125°C - ideal for battery-powered infotainment modules and ADAS sensor power rails.
For engineers reviewing the NCV8623MN-33R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 3.3 V fixed output, DFN6 3×3 mm package, 170 µA quiescent current in ON mode, and −90 dB line regulation - all critical for noise-sensitive automotive subsystems requiring stable, low-power biasing.
Technical Context
The NCV8623MN-33R2G employs a bandgap reference-based error amplifier with internal current limiting and thermal shutdown circuitry. Its architecture supports ceramic output capacitors with ESR from 0 to 3.0 Ω and enables stable operation without external compensation.
It integrates TTL/CMOS-compatible ON/OFF control with 0.3 V logic-low threshold and 2.2 V logic-high threshold, and achieves −70 dB ripple rejection at 1.0 kHz while maintaining 20 mV load regulation over 150 mA full-load range - confirming suitability for dynamic load environments like camera ISP power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2.5% (ensures compatibility with 3.3 V logic I/O and microcontroller core rails) |
| Max Output Current | 150 mA (supports moderate-power sensors, RF transceivers, and display drivers) |
| Dropout Voltage | 137 mV typ. at 100 mA (enables >3.43 V input operation down to near-end-of-battery life) |
| Output Noise | 25 µVRMS (100 Hz–100 kHz, with 10 nF bypass) - meets stringent analog/RF supply requirements |
| Quiescent Current | 170 µA typ. in ON mode, 100 nA in OFF mode (extends battery runtime in always-on vehicle modules) |
| Operating Temp Range | −40°C to +125°C (AEC-Q100 Grade 1 qualified for under-hood and cabin applications) |
| Ripple Rejection | −70 dB @ 1.0 kHz (suppresses switching noise from upstream DC-DC converters) |
| Line Regulation | 2.0 mV typ. (Vin = Vout+1.0 V to 12 V) - ensures stable output despite battery voltage sag or surge |
Pinout & Package
NCV8623MN-33R2G uses the DFN6 3×3 mm package (Case 488AE, MN suffix), featuring an exposed thermal pad for enhanced heat dissipation. Pin 1 is VIN; Pin 2 and Pin 5 are GND; Pin 3 is VOUT; Pin 4 is ON/OFF; Pin 6 is Bypass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input Power Supply | Accepts 3.43 V to 12 V input; must be decoupled with ≥1.0 µF ceramic capacitor near pin |
| GND (Pins 2 & 5) | Ground Reference | Dual ground pins reduce impedance path; both must connect to low-impedance PCB ground plane |
| VOUT (Pin 3) | Regulated Output | Delivers stable 3.3 V; requires ≥1.0 µF output capacitor with ESR ≤3.0 Ω |
| ON/OFF (Pin 4) | Enable Control Input | TTL/CMOS-compatible; <0.3 V = OFF, >2.2 V = ON; high-impedance input draws ≤2.5 µA |
| BYPASS (Pin 6) | Noise Filtering Node | Connects to 10 nF capacitor to reduce output noise to 25 µVRMS; optional for faster startup |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 25 µVRMS (100 Hz–100 kHz) with 10 nF bypass - enables clean power for ADCs, PLLs, and RF receivers |
| Automotive qualification | AEC-Q100 Grade 1 compliant with PPAP capability - validated for production automotive use |
| Low-quiescent-current enable | 100 nA OFF-state current - preserves battery charge in parked-vehicle monitoring circuits |
| Wide-input, low-dropout operation | 12 V max input, 137 mV dropout at 100 mA - supports 12 V battery systems with minimal headroom loss |
| Robust protection suite | Thermal shutdown (150°C) and short-circuit current limit (175 mA min) - prevents failure under fault conditions |
| Ceramic capacitor compatible | Stable with 0–3.0 Ω ESR output caps - eliminates need for costly tantalum or polymer capacitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2033PDQNR | Lower IQ (6.5 µA), higher PSRR (−80 dB @ 100 kHz), but only −40°C to +125°C industrial grade (not AEC-Q100) | Lacks automotive qualification and fails PPAP requirements for OEM programs | Select only for non-automotive portable or industrial designs where qualification is not mandated |
| MCP1703T-3302E/MB | Higher dropout (500 mV @ 250 mA), lower PSRR (−55 dB @ 1 kHz), no bypass pin for noise optimization | Insufficient noise performance for RF/analog loads; limited thermal margin at 150 mA | Consider only for cost-sensitive, non-noise-critical 3.3 V rails with ample input headroom |
Compared with TPS7A2033PDQNR and MCP1703T-3302E/MB, the NCV8623MN-33R2G uniquely combines AEC-Q100 qualification, 25 µVRMS noise with bypass, and 137 mV dropout - making it the only drop-in solution for automotive infotainment and ADAS power domains requiring both reliability and spectral purity.

FAQ
What is the maximum input voltage rating for the NCV8623MN-33R2G?
The NCV8623MN-33R2G has a maximum input voltage rating of 12 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable long-term use, design input rails to remain ≤12 V under all conditions including load dump transients - external clamping may be required in 12 V automotive systems.
Does the NCV8623MN-33R2G require an external bypass capacitor to meet its 25 µVRMS noise specification?
Yes - the 25 µVRMS output noise specification for the NCV8623MN-33R2G is measured with a 10 nF capacitor connected to the BYPASS pin. Without it, noise rises to 65 µVRMS. The bypass capacitor directly filters reference noise; omitting it degrades noise performance but does not affect regulation stability or basic functionality.
Is the NCV8623MN-33R2G pin-compatible with other variants in the NCV8623 family?
Yes - all NCV8623 variants (e.g., NCV8623MN-28R2G, NCV8623MN-50R2G) share identical DFN6 3×3 mm packaging and pinout. Only the marked output voltage differs; electrical behavior (dropout, noise, protection) remains consistent across the family, enabling board-level voltage scaling without layout changes.
What thermal derating applies to the NCV8623MN-33R2G at 125°C ambient?
At TA = 125°C, the NCV8623MN-33R2G's maximum sustainable output current drops due to thermal limits. With RθJA = 161°C/W and TJmax = 150°C, usable power dissipation falls to ~155 mW - limiting practical IOUT to ~45 mA at 12 V input. Use PCB copper pour under the exposed pad to improve thermal performance in high-temp zones.
Can the NCV8623MN-33R2G operate without an output capacitor?
No - the NCV8623MN-33R2G requires a minimum 1.0 µF output capacitor for stability, as confirmed in the Application Hints section. Omitting it risks oscillation and unregulated output. Ceramic capacitors with ESR between 0 and 3.0 Ω are supported; tantalum types are also acceptable if ESR falls within that range.
