Product details
Overview
NCV8535MN250R2G from onsemi is an automotive-grade, ultra-high-accuracy low-dropout linear regulator delivering 5.0 V fixed output at up to 500 mA. It features ±0.9% output voltage accuracy over line/load/temperature, 260 mV typical dropout at full load, and reverse bias protection. Designed for DSP supply and display power rails in automotive infotainment systems.
For engineers reviewing the NCV8535MN250R2G datasheet, pinout, applications, or equivalent options, this page provides verified pin functions, thermal performance data, noise-reduction implementation guidance, and AEC-Q100-compliant selection criteria for safety-critical embedded power domains.
Technical Context
The NCV8535MN250R2G integrates a precision bandgap reference, error amplifier, and PMOS pass transistor in a single-stage LDO architecture. Its sense pin enables remote output voltage monitoring for improved regulation under PCB trace resistance, while the NR pin accepts a 10 nF capacitor to reduce output noise by up to 40% (from 93 µVrms to 58 µVrms).
It operates across −40 °C to +125 °C junction temperature with thermal shutdown at 160 °C and current limiting at 930 mA. Stability requires only 1.0 µF output capacitance-compatible with MLCCs-and no minimum load current is needed, simplifying low-power sleep-mode design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±0.9% at 25 °C; ±1.5% over −40 °C to +125 °C - ensures stable core logic supply under automotive thermal cycling. |
| Dropout Voltage | 340 mV max at 500 mA load - enables operation from 5.4 V input down to 5.0 V output, critical for battery-sag conditions. |
| Quiescent Current | 9.0 mA typical in regulation; 0.07 µA in shutdown - supports <1 µA system standby current when paired with enable control. |
| Output Noise | 58 µVrms with 10 nF NR capacitor (10 Hz–100 kHz) - meets low-noise requirements for analog sensor interfaces and ADC references. |
| Input Voltage Range | 2.9 V to 12 V - compatible with 5 V rail and automotive 12 V battery systems with transient suppression. |
| Thermal Protection | 160 °C junction shutdown with automatic recovery - prevents permanent damage during sustained overload or poor heatsinking. |
| Reverse Bias Current | 10 µA max when VOUT = 5.0 V and VIN = 0 V - blocks backfeed from downstream circuits into the regulator input. |
Pinout & Package
NCV8535MN250R2G uses the DFNW10 (Case 507AM) 3×3 mm thermally enhanced package with exposed EPAD. The 10-pin layout supports high-current routing and low thermal resistance (θJL2 = 17 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Vout | Main regulated 5.0 V output; bypassed to GND with ≥1.0 µF capacitor for stability and transient response. |
| 3 | SENSE | Remote sensing input; connects directly to load-side Vout to compensate for PCB trace IR drop. |
| 4 | GND | Power ground reference; must be connected to low-impedance ground plane and tied to EPAD. |
| 5, 6 | NC | No-connect pins; left unconnected per datasheet - no internal function or test access. |
| 7 | NR | Noise reduction node; accepts 10 nF capacitor to ground to suppress high-frequency output ripple. |
| 8 | SD | Active-low shutdown input; pulled high to Vin for normal operation; driven low to disable output and reduce IQ to 0.07 µA. |
| 9, 10 | Vin | Input power supply (2.9–12 V); requires ≥1.0 µF input capacitor close to pins for EMI filtering and transient immunity. |
| EPAD | Thermal Pad | Exposed copper pad; must be soldered to solid GND plane for thermal dissipation and electrical grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 260 mV typ. at 500 mA enables use in tight voltage-margin applications like post-buck LDO stages. |
| No minimum load requirement | Stable with zero output current - eliminates need for wasteful bleed resistors in always-on monitoring circuits. |
| MLCC-compatible stability | Works with ceramic capacitors as small as 1.0 µF - reduces BOM cost and board area vs. tantalum alternatives. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C) qualification with PPAP capability - meets automotive functional safety baseline for power ICs. |
| Reverse bias protection | Blocks >99% of reverse current flow when Vin = 0 V and Vout = 5.0 V - prevents backfeeding into upstream supplies. |
Applications
| Automotive Infotainment Display Power | DSP Core Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A4700RGWR | 20 V input, 1 A output, 4 µVrms noise, but requires 2.2 µF min. output cap and has no SENSE pin. | Lacks remote sensing and reverse bias protection - unsuitable for hot-swap or high-precision remote load regulation. | Choose for higher current or lower noise where SENSE and reverse protection are not required. |
| MCP1825-5002E/DB | 500 mA, ±2% accuracy, 350 mV dropout, no NR or SENSE pins, non-automotive grade. | Not AEC-Q100 qualified; wider accuracy tolerance limits use in safety-critical automotive domains. | Acceptable for cost-sensitive consumer electronics where automotive qualification and ±0.9% accuracy are unnecessary. |
Compared with TPS7A4700RGWR and MCP1825-5002E/DB, the NCV8535MN250R2G uniquely combines AEC-Q100 Grade 1 qualification, ±0.9% accuracy, SENSE pin for remote regulation, and integrated reverse bias protection - making it the only option qualified for ASIL-B–aligned power domains in modern infotainment ECUs.

FAQ
What is the maximum input voltage rating for NCV8535MN250R2G?
The NCV8535MN250R2G supports an absolute maximum input voltage of +16 V, with recommended operating range from 2.9 V to 12 V. Operation above 12 V is permissible only for short-duration transients (e.g., automotive load dump), provided thermal limits are maintained and external clamping is used.
Does NCV8535MN250R2G require an external capacitor on the SENSE pin?
No, the NCV8535MN250R2G does not require an external capacitor on the SENSE pin. Pin 3 (SENSE) is a high-impedance input that connects directly to the load-side Vout node to compensate for PCB trace resistance; adding capacitance here would degrade transient response and stability.
Can NCV8535MN250R2G operate without the NR capacitor?
Yes, the NCV8535MN250R2G operates fully functional without the NR capacitor. The NR pin is optional: omitting the 10 nF capacitor results in higher output noise (93 µVrms vs. 58 µVrms), but all regulation, protection, and enable functions remain active and specified.
What is the thermal resistance (θJA) of NCV8535MN250R2G on a standard PCB?
On a 35 × 35 × 1.5 mm FR4 board with 2 oz copper, the NCV8535MN250R2G achieves θJA = 66 °C/W. This value assumes proper EPAD soldering to a solid GND plane; inadequate thermal land design can increase θJA beyond 100 °C/W, risking thermal shutdown at full load.
Is NCV8535MN250R2G pin-compatible with other NCV8535 variants?
Yes, all NCV8535 fixed-output versions-including NCV8535MN250R2G (5.0 V), NCV8535MN330R2G (3.3 V), and NCV8535MN280R2G (2.8 V)-share identical DFNW10 pinout, package dimensions, and terminal functions. Only the output voltage and marking differ.
