Product details

Overview

NCV8535MN280R2G from onsemi is an automotive-grade, ultra-high-accuracy low-dropout linear regulator delivering 2.8 V fixed output at up to 500 mA. It features ±0.9% output accuracy over line/load/temperature, 260 mV typical dropout at full load, reverse bias protection, and stability with any 1.0 µF capacitor-including MLCCs-without minimum load requirement. It serves as a precision power source for DSP cores, display logic, and camera sensor rails in automotive infotainment systems.

For engineers reviewing the NCV8535MN280R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, ultra-low noise (36 µVrms w/10 nF C_NR), shutdown current of 70 nA, thermal shutdown at 160 °C, and DFNW10 (5 mm × 6 mm) package with exposed thermal pad.

Technical Context

The NCV8535MN280R2G employs a PMOS pass transistor architecture enabling ultra-low dropout and no minimum load requirement. Its internal reference is trimmed to ±0.9% at 25 °C and maintains ±1.5% accuracy across −40 °C to +125 °C, supported by integrated sense and noise reduction (NR) pins for enhanced regulation fidelity.

It integrates reverse bias protection (limiting reverse current to 10 µA when V_OUT − V_IN ≤ 7 V), thermal shutdown at 160 °C, and current limiting. The SD pin provides active-low enable control with 0.4 V turn-off threshold and 2.0 V turn-on threshold, while the NR pin accepts a 10 nF capacitor to reduce output noise by ~20 µVrms.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.8 V ±0.9% at 25 °C; ±1.5% over −40 °C to +125 °C - ensures stable core voltage for automotive microcontrollers.
Max Output Current	500 mA continuous - sufficient for powering multiple low-voltage logic blocks or sensor interfaces.
Dropout Voltage	340 mV typ. at 500 mA - enables operation from 3.2 V input down to 2.8 V output, critical for battery-powered systems.
Ground Current	9.0 mA at 500 mA load; 70 nA in shutdown - minimizes quiescent power loss in always-on automotive modules.
Output Noise	36 µVrms (with 10 nF C_NR) - meets stringent noise requirements for ADC reference supplies and RF front-end biasing.
Input Voltage Range	2.9 V to 12 V - compatible with 3.3 V, 5 V, and automotive 12 V supply rails after pre-regulation.
Thermal Shutdown	160 °C junction temperature - protects against sustained overload or poor PCB thermal design.

Pinout & Package

NCV8535MN280R2G uses the DFNW10 (Case 507AM) 5 mm × 6 mm wettable flank package with exposed thermal pad (EPAD) for enhanced thermal performance. The package is Pb-free and RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 2	Vout	Regulated 2.8 V output; requires ≥1.0 µF bypass capacitor to ground for stability.
3	SENSE	Feedback node for output voltage sensing; connects directly to pins 1 and 2 for accurate regulation.
4	GND	Power ground reference; must be connected to low-impedance system ground plane.
5, 6	NC	No internal connection; left unconnected per design.
7	NR	Noise reduction terminal; optional 10 nF capacitor to ground reduces output noise by ~20 µVrms.
8	SD	Active-low shutdown input; <0.4 V disables regulator, >2.0 V enables; float or tie to Vin if unused.
9, 10	Vin	Input supply (2.9–12 V); requires ≥1.0 µF input capacitor close to pins for transient immunity.
EPAD	Thermal Pad	Exposed copper pad; must be soldered to solid ground plane for thermal dissipation and EMI reduction.

Key Features

Feature	Design Value
Ultra-High Accuracy	±0.9% output tolerance at 25 °C enables direct replacement of higher-cost references in safety-critical subsystems.
No Minimum Load Requirement	Stable operation down to 0 mA load eliminates need for dummy loads-reducing BOM count and power waste.
MLCC-Compatible Stability	Guaranteed stability with any 1.0 µF capacitor type (including low-ESR MLCCs) simplifies layout and lowers cost.
Reverse Bias Protection	Limits reverse current to 10 µA when V_OUT > V_IN, preventing backfeed damage during hot-swap or battery disconnect events.
AEC-Q100 Qualified	Qualified to Grade 1 (−40 °C to +125 °C) with PPAP capability-meets automotive functional safety readiness requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV73328PDBVR	300 mA max output, 170 mV dropout at 300 mA, no NR pin, SOT-23-5 package.	Lower current capacity and no noise reduction option; suitable only for non-noise-sensitive digital logic.	Select when board space is constrained and noise sensitivity is low; not recommended for analog sensor or audio rails.
NCP1117ST28T3G	800 mA max output, 1.2 V dropout at 800 mA, no AEC-Q100 qualification, TO-220/SOT-223 packages.	Larger thermal footprint, higher dropout, and non-automotive qualification limit use to industrial/commercial designs.	Choose for cost-sensitive non-automotive applications requiring higher current; avoid where AEC-Q100 or compact DFNW is mandatory.

Compared with TLV73328PDBVR and NCP1117ST28T3G, the NCV8535MN280R2G uniquely combines AEC-Q100 Grade 1 qualification, 500 mA output, ultra-low noise (36 µVrms), and MLCC-compatible stability in a thermally enhanced DFNW10 package-making it the only choice for automotive DSP and camera sensor biasing where precision, noise, and reliability are co-constrained.

FAQ

What is the output voltage tolerance of the NCV8535MN280R2G over temperature?

The NCV8535MN280R2G maintains ±1.5% output voltage accuracy over the full automotive temperature range of −40 °C to +125 °C, with tighter ±0.9% tolerance specified at 25 °C. This is verified across line, load, and temperature per AEC-Q100 stress testing, ensuring reliable operation in engine bay and cabin environments where thermal cycling is severe.

Does the NCV8535MN280R2G require an external capacitor on the NR pin?

The NR pin on the NCV8535MN280R2G is optional: connecting a 10 nF capacitor between NR and GND reduces output noise from 52 µVrms to 36 µVrms. If noise performance is not critical, the NR pin may be left unconnected or tied to GND. The regulator remains fully functional and stable without it.

Can the NCV8535MN280R2G operate with ceramic capacitors smaller than 1.0 µF?

No-the NCV8535MN280R2G is guaranteed stable only with ≥1.0 µF output capacitance, regardless of capacitor type (MLCC, tantalum, or aluminum polymer). Using smaller values risks instability and oscillation, especially under dynamic load conditions. The 1.0 µF minimum applies to both input and output capacitors.

What is the maximum input voltage rating for the NCV8535MN280R2G?

The absolute maximum input voltage for the NCV8535MN280R2G is +16 V, but the recommended operating range is 2.9 V to 12 V. Exceeding 12 V continuously increases thermal stress and may trigger thermal shutdown; operation above 16 V risks permanent damage per the Absolute Maximum Ratings table.

How does reverse bias protection work on the NCV8535MN280R2G?

The NCV8535MN280R2G limits reverse current to ≤10 µA when V_OUT exceeds V_IN by up to 7 V (i.e., V_OUT − V_IN ≤ 7 V). This prevents backfeed into upstream supplies during hot-swap or battery disconnect events. If V_OUT − V_IN > 7 V, reverse bias protection is not guaranteed, and external diode protection may be needed.
