Product details

Overview

NCV8535ML330R2G from onsemi is an automotive-grade, ultra-high-accuracy low-dropout linear regulator delivering 3.3 V at up to 500 mA with ±0.9% output voltage accuracy over line/load/temperature, 340 mV typical dropout at full load, and 46 µVrms output noise (with 10 nF C_NR). It enables stable power for DSPs, camera modules, and infotainment SoCs in vehicles where reverse bias protection, zero minimum load requirement, and MLCC compatibility are critical.

For engineers reviewing the NCV8535ML330R2G datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DFN10), validated fixed-3.3V pin configuration, confirmed AEC-Q100 qualification, and real-world design implications of its no-minimum-load stability, NR-pin noise reduction, and reverse-bias current limit (10 µA).

Technical Context

The NCV8535ML330R2G implements a PMOS pass transistor architecture enabling ultra-low dropout and inherent reverse-current blocking without external components. Its internal reference is trimmed to ±0.9% at 25°C and maintains ±1.5% over −40°C to +125°C, supporting automotive under-hood operation.

Stability is guaranteed with any capacitor ≥1.0 µF-including ceramic MLCCs-without ESR requirements, eliminating output capacitor selection risk. The dedicated SENSE pin (pins 1–2 tied internally for fixed versions) and optional NR pin (pin 7) allow precise remote sensing and configurable noise filtering via external 10 nF capacitor.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.3 V ±0.9% at 25°C; ±1.5% over −40°C to +125°C - ensures consistent logic-level supply for 3.3 V microcontrollers and interfaces.
Max Output Current	500 mA continuous, 800 mA peak - supports moderate-power digital loads like image sensors or baseband processors without thermal derating at TA ≤ 85°C.
Dropout Voltage	340 mV typ. at 500 mA - enables regulation from 3.64 V input, critical for battery-powered systems operating down to 3.6 V.
Ground Current	9.0 mA at 500 mA load; 0.07 µA in shutdown - minimizes quiescent loss in always-on vehicle modules (e.g., CAN wake-up circuits).
Output Noise	46 µVrms (10 Hz–100 kHz) with 10 nF C_NR - meets stringent noise budgets for ADC references and RF front-end biasing.
Input Voltage Range	2.9 V to 12 V - compatible with 12 V automotive battery rails including cold-crank (down to ~6 V) and start-stop transients.
Protection Features	Thermal shutdown (160°C), current limiting (~900 mA short-circuit), reverse bias protection (10 µA max reverse current when V_OUT > V_IN by ≤7 V) - ensures robustness in harsh automotive environments.

Pinout & Package

NCV8535ML330R2G uses the DFN10 (Case 485C) 3×3 mm exposed-pad package. The thermal pad (EPAD) must be soldered to a PCB ground plane for thermal performance (θ_JA = 66°C/W on 1-pad board).

Pin/Terminal	Circuit Role	Design Meaning
1, 2	V_OUT	Regulated 3.3 V output; bypass to GND with ≥1.0 µF capacitor - pins are paralleled internally for current sharing and low-impedance output.
3	SENSE	Sense input tied to pins 1–2 internally for fixed version - enables remote sensing to compensate for PCB trace IR drop in high-accuracy applications.
4	GND	Power ground reference; connects to EPAD - forms primary return path for load current and critical for noise rejection.
5, 6	NC	No connect - must remain unconnected; no internal circuitry attached.
7	NR	Noise reduction input; accepts 10 nF capacitor to GND - reduces output noise by ~30% (from 69 µVrms to 46 µVrms) for sensitive analog rails.
8	SD	Active-low shutdown control; <2.0 V = ON, >0.4 V = OFF - allows system-level power sequencing and ultra-low standby current (0.07 µA).
9, 10	V_IN	Input supply (2.9–12 V); decoupled with ≥1.0 µF capacitor - dual pins reduce resistance/inductance for high-frequency transient response.

Key Features

Feature	Design Value
Ultra-high accuracy	±0.9% initial tolerance at 25°C, ±1.5% over full automotive temperature range - eliminates need for post-production calibration in ADAS sensor supplies.
No minimum load requirement	Stable with zero output current - enables use in standby modes where downstream logic may be fully powered down (e.g., key-off CAN nodes).
MLCC-compatible stability	Stable with any ≥1.0 µF capacitor type, including low-ESR ceramic - removes capacitor cost/size constraints and simplifies BOM.
Reverse bias protection	Blocks reverse current flow from V_OUT to GND when V_IN = 0 V and V_OUT = 3.3 V (I_OUTR ≤ 10 µA) - prevents backfeeding into failed upstream supplies.
AEC-Q100 qualified	Grade 1 (−40°C to +125°C junction), PPAP-capable - certified for safety-critical automotive applications including instrument clusters and body control modules.

FAQ

What is the maximum input voltage rating for the NCV8535ML330R2G?

The NCV8535ML330R2G has an absolute maximum input voltage rating of +16 V, but its recommended operating range is 2.9 V to 12 V per the datasheet. Operation above 12 V is permissible only for short-duration transients (e.g., automotive load dump), and sustained voltage beyond 12 V risks exceeding thermal limits or degrading long-term reliability. The device includes internal protection against overvoltage stress within these bounds.

Does the NCV8535ML330R2G require an external capacitor on the NR pin to function?

No, the NCV8535ML330R2G operates fully functional without any capacitor on the NR (pin 7) - the NR pin is optional. When left open or tied to GND, the device delivers 69 µVrms output noise. Adding a 10 nF capacitor between NR and GND reduces noise to 46 µVrms, but this is only necessary in noise-sensitive applications like ADC references or RF bias rails.

Can the NCV8535ML330R2G be used with ceramic output capacitors?

Yes, the NCV8535ML330R2G is explicitly designed to be stable with any capacitor ≥1.0 µF, including low-ESR ceramic (MLCC) types. Unlike many older LDOs, it imposes no minimum ESR requirement, eliminating the need for costly tantalum or aluminum electrolytic capacitors and enabling smaller, more reliable, and lower-profile designs.

What does "reverse bias protection" mean for the NCV8535ML330R2G?

Reverse bias protection in the NCV8535ML330R2G means that when the input (V_IN) is forced to 0 V while the output (V_OUT) is held at 3.3 V (e.g., due to backfeed from another supply), the device limits reverse current from V_OUT to GND to ≤10 µA. This prevents battery drain and protects upstream circuitry during fault conditions - a critical feature in distributed automotive power architectures.

Is the NCV8535ML330R2G pin-compatible with other variants in the NCV8535 family?

Yes, all fixed-output variants of the NCV8535 (e.g., NCV8535ML180R2G, NCV8535ML250R2G) share identical DFN10 pinout and package dimensions. The only differences are output voltage and laser-trimmed internal feedback network - allowing drop-in replacement across voltages without PCB redesign, provided thermal and layout constraints are met.
