Product details

Overview

NCV8535ML300R2G from onsemi is a fixed-output, 3.0 V, 500 mA ultra-high-accuracy low-dropout linear regulator with ±0.9% output voltage accuracy at 25 °C, 260 mV typical dropout at full load, and 37 µV_RMS output noise (with 10 nF C_NR). It features reverse bias protection, thermal shutdown, current limiting, and stable operation with only 1.0 µF MLCC output capacitance - used in automotive infotainment power rails and DSP core supplies.

For engineers reviewing the NCV8535ML300R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, no-minimum-load stability, NR pin for noise reduction, SD pin for enable control, and DFN10 (485C) package compatibility with high-density PCB layouts.

Technical Context

The NCV8535ML300R2G implements a PMOS pass transistor architecture enabling ultra-low dropout and reverse bias protection without external components. Its internal reference is trimmed to ±0.9% over line/load/temperature, and the integrated noise reduction (NR) pin allows optional 10 nF capacitor connection to reduce output noise by ~30%.

Stability is guaranteed across all ceramic capacitor types (including X5R/X7R MLCCs) down to 1.0 µF, eliminating ESR requirements. The shutdown (SD) pin provides logic-level enable/disable with 0.07 µA quiescent current in shutdown mode and 2.0 V/0.4 V threshold levels.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0 V ±0.9% at 25 °C; ensures precise core voltage for 3.3 V I/O-tolerant microcontrollers.
Max Output Current	500 mA continuous; supports mid-power DSPs and FPGA I/O banks without derating at +85 °C.
Dropout Voltage	340 mV typ. at 500 mA; enables regulation from 3.4 V input - critical for battery-powered systems near end-of-discharge.
Ground Current	9.0 mA at 500 mA load; low quiescent consumption preserves battery life in always-on automotive modules.
Output Noise	37 µV_RMS (10 Hz–100 kHz, with 10 nF C_NR); meets stringent analog supply requirements for ADC references and audio codecs.
Operating Input Range	2.9 V to 12 V; compatible with 5 V rail, 12 V automotive battery (with pre-regulation), and wide-input industrial SMPS outputs.
Thermal Shutdown	160 °C junction limit; protects against sustained overload or poor heatsinking in sealed enclosures.

Pinout & Package

NCV8535ML300R2G uses the DFN10 (Case 485C) 3×3 mm thermally enhanced package with exposed EPAD. Pin 1–2 are paralleled VOUT; Pin 3 is SENSE (tied to VOUT for fixed version); Pin 4 is GND; Pins 5–6 are NC; Pin 7 is NR; Pin 8 is SD; Pins 9–10 are paralleled VIN; EPAD must be soldered to PCB ground plane for thermal and electrical performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2	VOUT	Regulated 3.0 V output; paralleled pins reduce IR drop and improve current sharing in high-current paths.
3	SENSE	Feedback node tied directly to VOUT pins; enables remote sensing to compensate for PCB trace resistance.
4	GND	Power ground reference; connects to EPAD for lowest thermal resistance (θ_JL2 = 17 °C/W).
7	NR	Noise reduction terminal; adding 10 nF capacitor reduces output noise by ~30% - essential for RF-sensitive applications.
8	SD	Active-high shutdown control; pulls VOUT to near-zero when driven low; requires pull-up if unused.
9, 10	VIN	Input supply (2.9–12 V); paralleled pins minimize inductance and support high di/dt transients from digital loads.

Key Features

Feature	Design Value
AEC-Q100 qualified	Rated for automotive Grade 1 (−40 °C to +125 °C ambient), PPAP-capable - suitable for front-end ADAS camera modules.
No minimum load required	Stable down to 0 mA output current; eliminates need for dummy loads in low-power sleep modes.
Reverse bias protection	Blocks >10 µA reverse current when V_OUT > V_IN (ΔV ≤ 7 V); prevents backfeed in multi-rail systems during power sequencing.
Stable with any 1.0 µF capacitor	Validated with X5R/X7R MLCCs; avoids tantalum or electrolytic dependencies - reduces BOM count and board area.
Ultra-low shutdown current	0.07 µA max; enables <1 µW system standby power - critical for ISO 26262 ASIL-B functional safety domains.

FAQ

What is the maximum input voltage rating for the NCV8535ML300R2G?

The NCV8535ML300R2G has an absolute maximum input voltage rating of +16 V. Operation above 12 V is not recommended for continuous use due to thermal constraints; the device is specified for 2.9 V to 12 V normal operation per datasheet Section 4. Exceeding 16 V risks permanent damage to the internal PMOS pass element.

Does the NCV8535ML300R2G require an external capacitor on the NR pin?

No - the NR pin on the NCV8535ML300R2G is optional. When left unconnected, the device operates with baseline 56 µV_RMS noise (no C_NR). Adding a 10 nF capacitor between NR and GND reduces output noise to 37 µV_RMS, as verified in Electrical Characteristics Table for 3.0 V version. This configuration is recommended for analog-sensitive circuits.

Can the NCV8535ML300R2G be used without connecting the SENSE pin?

Yes - for the NCV8535ML300R2G (fixed 3.0 V version), the SENSE pin must be connected directly to the VOUT pins (1 and 2) per datasheet Pin Function Description. It is not optional; leaving it floating violates the internal feedback path and causes output regulation failure. This differs from adjustable versions where SENSE is replaced by ADJ.

Is the NCV8535ML300R2G pin-compatible with other NCV8535 variants?

Yes - all NCV8535 fixed-output variants (e.g., NCV8535ML180R2G, NCV8535ML330R2G) share identical DFN10 (Case 485C) pinout and package dimensions. Only the output voltage and marking differ; no PCB redesign is needed when migrating between 1.5 V–5.0 V fixed versions, provided thermal and input voltage constraints remain valid.

What is the thermal resistance (θ_JA) of the NCV8535ML300R2G in standard layout?

The NCV8535ML300R2G has a junction-to-air thermal resistance (θ_JA) of 215 °C/W on a minimal-pad board (1-layer 2 oz copper, 35 × 35 mm FR4), and 66 °C/W on a full-pad board (JEDEC-standard high-conductivity test board). For production designs, thermal performance depends heavily on EPAD soldering quality and copper pour area - achieving <100 °C/W typically requires ≥200 mm² of 2 oz copper connected to the EPAD.
