Product details
Overview
NCV8535MN150R2G from onsemi is an automotive-grade, ultra-high-accuracy low-dropout linear regulator delivering 500 mA output with ±0.9% initial accuracy at 25 °C, 260 mV typical dropout at full load, and reverse bias protection. It operates from 2.9 V to 12 V input and provides a fixed 1.5 V output - ideal for powering DSP cores, FPGA I/O banks, and automotive infotainment SoCs requiring stable, low-noise, low-quiescent-current regulation.
For engineers reviewing the NCV8535MN150R2G datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for AEC-Q100-compliant power design in safety-critical embedded systems.
Technical Context
The NCV8535MN150R2G integrates a precision bandgap reference, error amplifier, and PMOS pass transistor in a DFN10 (4.0 × 4.0 mm) package with exposed thermal pad. Its architecture enables stability with any capacitor ≥1.0 µF - including MLCCs - without minimum load current requirements.
It features dedicated SENSE (for remote voltage sensing), NR (noise reduction via external 10 nF capacitor), SD (active-low shutdown), and reverse-bias protection that limits reverse current to 10 µA when Vin = 0 V and Vout = 1.5 V - critical for battery-backed subsystems and hot-swap applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±0.9% at 25 °C; ±1.5% over −40 °C to +125 °C - ensures core logic compliance across automotive temperature range. |
| Max Output Current | 500 mA continuous; 860 mA peak - supports burst-mode digital loads like microcontroller wake-up events. |
| Dropout Voltage | 940 mV typ. at 500 mA (Vin ≥ 2.9 V); enables operation down to 2.44 V input - suitable for 3.3 V rail derivation in degraded supply conditions. |
| Quiescent Current | 0.07 µA in shutdown; 0.8–9.0 mA in regulation - extends battery life in always-on vehicle modules. |
| Output Noise | 31 µVRMS (with 10 nF CNR); 51 µVRMS (no CNR) - meets noise-sensitive analog/RF supply requirements. |
| Input Voltage Range | 2.9 V to 12 V - compatible with 12 V automotive battery systems after pre-regulation or LDO cascading. |
| Thermal Protection | 160 °C junction shutdown with hysteresis - prevents thermal runaway during sustained overload or poor PCB heatsinking. |
Pinout & Package
NCV8535MN150R2G uses the DFN10 (Case 485C, 4.0 × 4.0 × 0.9 mm) package with exposed EPAD for thermal dissipation. The device is pin-compatible with other NCV8535 fixed-output variants in the same footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Vout | Regulated 1.5 V output; bypassed to GND with ≥1.0 µF capacitor - low-ESR MLCC recommended for transient response. |
| 3 | SENSE | Remote sense input; connect directly to load-side Vout to compensate for PCB trace IR drop - improves regulation accuracy under dynamic load. |
| 4 | GND | Power ground; tie to system ground plane and EPAD - mandatory for thermal and electrical stability. |
| 5, 6 | NC | No-connect pins; must remain unconnected - no internal circuitry or test functions attached. |
| 7 | NR | Noise reduction node; connect 10 nF capacitor to GND to reduce output noise by ~35% - optional but recommended for RF/analog supplies. |
| 8 | SD | Active-low shutdown control; pulled high internally; drive ≤0.4 V to disable output - enables system-level power sequencing. |
| 9, 10 | Vin | Input supply (2.9–12 V); decouple with ≥1.0 µF ceramic capacitor near pins - minimizes input ripple and EMI susceptibility. |
| EPAD | Thermal Pad | Exposed copper pad; must be soldered to solid GND plane - reduces θJA from 215 °C/W to 66 °C/W per JEDEC 51 standards. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-high accuracy | ±0.9% initial tolerance at 25 °C - eliminates need for post-production calibration in ADAS sensor power rails. |
| No minimum load requirement | Stable down to 0 mA output - enables use in standby modes where downstream circuits draw sub-µA current. |
| Capacitor flexibility | Stable with any ≥1.0 µF capacitor type (MLCC, tantalum, polymer) - simplifies BOM and avoids costly low-ESR constraints. |
| Reverse bias protection | Blocks >99.9% reverse current (≤10 µA) when Vin = 0 V and Vout = 1.5 V - prevents backfeeding into failed upstream regulators. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C) qualification with PPAP capability - meets functional safety requirements for ASIL-B systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8535MN150R2 | Same silicon, non-Pb-free packaging (SnPb plating); identical electrical specs and pinout. | Not compliant with RoHS or ELV directives - restricted to legacy automotive repair or non-EU production. | Select only if Pb-free compliance is waived and legacy board assembly is required. |
| TLV73315PDBVR | Lower max current (300 mA), higher dropout (300 mV @ 300 mA), no SENSE/NR pins, no reverse bias protection. | Lacks AEC-Q100 qualification and automotive temp range - limited to consumer-grade portable electronics. | Use only in cost-sensitive, non-automotive designs where 1.5 V/300 mA and −40 °C to +85 °C suffice. |
Compared with NCV8535MN150R2G, the NCV8535MN150R2 offers identical performance but fails modern environmental compliance, while TLV73315PDBVR sacrifices automotive reliability, reverse protection, and 200 mA output headroom - making NCV8535MN150R2G the sole choice for AEC-Q100-compliant 1.5 V/500 mA power delivery.

FAQ
What is the maximum input voltage rating for NCV8535MN150R2G?
The NCV8535MN150R2G has an absolute maximum input voltage rating of +16 V, but its specified operating range is 2.9 V to 12 V. Operation above 12 V may compromise regulation accuracy and thermal performance, and is not guaranteed per the datasheet. For automotive 12 V battery systems with load-dump transients, external clamping or pre-regulation is recommended before the NCV8535MN150R2G input.
Does NCV8535MN150R2G require an external capacitor on the SENSE pin?
No, the SENSE pin of NCV8535MN150R2G is a high-impedance input and does not require an external capacitor. It must be connected directly to the load-side Vout node (not the regulator's Vout pin) using a dedicated trace to enable remote voltage sensing and compensate for PCB trace resistance - improving regulation accuracy under varying load currents.
Can NCV8535MN150R2G be used without the NR capacitor?
Yes, NCV8535MN150R2G operates fully functional without the NR (noise reduction) capacitor. The NR pin is optional: connecting a 10 nF capacitor to GND reduces output noise from 51 µVRMS to 31 µVRMS, but omission incurs no stability or functionality penalty - making it suitable for space-constrained layouts where noise margin permits.
Is NCV8535MN150R2G pin-compatible with other NCV8535 fixed-output variants?
Yes, all NCV8535 fixed-output versions - including NCV8535MN150R2G (1.5 V), NCV8535MN180R2G (1.8 V), and NCV8535MN250R2G (2.5 V) - share identical DFN10 (4.0 × 4.0 mm) pinout and package dimensions. This enables single-footprint board design with output voltage selection via BOM change only - reducing validation effort across vehicle platforms.
What thermal derating applies to NCV8535MN150R2G at 125 °C ambient?
At 125 °C ambient, NCV8535MN150R2G's maximum continuous output current is thermally limited to approximately 220 mA (assuming standard 2 oz copper on FR4 with 35 × 35 mm pad). This is derived from its 66 °C/W θJA (JEDEC 51), 160 °C thermal shutdown threshold, and 1.5 V × 220 mA = 330 mW power dissipation - ensuring safe operation below 135 °C junction temperature with margin.
