Product details
Overview
NCV59151MN50TYG from onsemi is an automotive-grade, 5.0 V fixed-output, 1.5 A very low-dropout (VLDO) linear regulator in DFN8-4x4 package, featuring 300 mV typical dropout at full load, ±2% output voltage accuracy over temperature, and integrated error flag and enable pins - used for post-regulation of FPGA core supplies in automotive ADAS domain controllers.
For engineers reviewing the NCV59151MN50TYG datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, real-world thermal and transient performance data, and precise alternative selection guidance for AEC-Q100-compliant power design.
Technical Context
The NCV59151MN50TYG implements a high-precision bandgap reference with internal error amplifier and PMOS pass transistor, enabling stable 5.0 V regulation with fast transient response (<500 µs startup time) and minimal line/load regulation (0.5% max). Its architecture supports ceramic output capacitors ≥47 µF and tolerates input voltages up to 13.5 V.
It integrates logic-compatible enable (TTL/CMOS) and open-collector error flag (active-low at 95% VOUT), with built-in protections including current limiting (2.0–3.0 A), thermal shutdown (125°C TJ), and reverse output current blocking (up to 6.5 V reverse bias).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% over −40°C to +125°C - ensures stable core supply for automotive SoCs without external feedback components. |
| Max Output Current | 1.5 A continuous - sufficient for powering FPGA I/O banks or DSP peripherals in compact ECU designs. |
| Dropout Voltage | 300 mV typical at 1.5 A - enables operation from 5.3 V input when battery dips to 5.5 V, critical for cold-crank scenarios. |
| Ground Current | 40–80 mA at 1.5 A load - low quiescent consumption preserves system efficiency in always-on domains. |
| PSRR | ≥60 dB at 100 Hz, ≥40 dB at 10 kHz - suppresses switching noise from upstream DC-DC converters feeding ADAS sensors. |
| Error Flag Threshold | 95% VOUT with 2% hysteresis - provides clean fault signaling for MCU watchdog monitoring without chatter during marginal conditions. |
| Enable Logic Levels | Enable threshold 1.8 V, shutdown <0.8 V - compatible with 3.3 V and 5 V microcontroller GPIOs without level-shifting. |
Pinout & Package
NCV59151MN50TYG uses the DFN8-4x4 (Case 488AF) thermally enhanced package with exposed pad (EP) connected to GND. The 8-pin layout supports high-current routing and efficient heat dissipation via PCB copper area (RJA = 75°C/W with 500 mm² 2 oz Cu).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | EN | CMOS/TTL-compatible enable input - pull high ≥1.8 V to activate regulator; <0.8 V disables with <5 µA shutdown current. |
| 2 | VIN | Main input supply pin - accepts 2.24 V to 13.5 V; must be decoupled with ≥1 µF ceramic capacitor within 1 inch. |
| 3 | GND | Power ground reference - connects internally to exposed pad; requires low-impedance PCB plane for thermal and noise control. |
| 4 | VOUT | Regulated 5.0 V output - drives load directly; requires ≥47 µF ceramic capacitor for stability and transient response. |
| 5 | FLG | Open-collector error flag - sinks up to 5 mA when VOUT drops below 95% nominal; requires external pull-up to VIN or logic rail. |
| 6 | NC | No internal connection - left unconnected per datasheet; not to be tied to any net. |
| 7 | NC | No internal connection - left unconnected per datasheet; not to be tied to any net. |
| 8 (EP) | Exposed Pad | Thermal and electrical ground - must be soldered to ≥500 mm² 2 oz Cu PCB area for RJA ≤75°C/W and safe 1.5 A operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +125°C junction operation - meets automotive reliability requirements for engine bay and infotainment modules. |
| Stable with ceramic capacitors | Supports ≥47 µF X7R/X5R MLCCs only - eliminates need for bulk electrolytic, reducing board space and improving lifetime. |
| Fast transient response | Load step recovery <10 µs for 100 mA–1.5 A steps - maintains voltage integrity during FPGA configuration bursts. |
| Reverse output current protection | Blocks >99% reverse current when VOUT > VIN by ≤6.5 V - prevents backup battery discharge in dual-supply systems. |
| Low ground current | 60 mA typical at 1.5 A load - improves overall system efficiency vs. legacy LDOs drawing >100 mA quiescent. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8170ASN500T1G | 500 mA output, 200 mV dropout at 500 mA, no error flag - smaller footprint but lower current capability. | Suitable for low-power MCU cores or sensor interfaces, not FPGA or high-current peripherals. | Select when board space is constrained and load <500 mA; verify thermal margin with RJA = 120°C/W. |
| TLV73350PDBVR | 300 mA output, 170 mV dropout at 300 mA, no AEC-Q100 rating - optimized for consumer portables, not automotive. | Lacks automotive qualification and reverse current protection; unsuitable for safety-critical ECUs. | Consider only for non-automotive industrial prototypes; avoid in production vehicles due to missing PPAP support. |
Compared with NCV59151MN50TYG, NCV8170ASN500T1G trades current capacity for size and cost in sub-500 mA roles, while TLV73350PDBVR offers lower dropout but lacks automotive validation and protection features required for vehicle deployment.

FAQ
What is the maximum input voltage rating for NCV59151MN50TYG?
The NCV59151MN50TYG has an absolute maximum input voltage of 18 V, but its recommended operating range is 2.24 V to 13.5 V. Operation above 13.5 V risks exceeding safe power dissipation limits and may trigger thermal shutdown. For automotive cold-crank resilience, it reliably regulates down to 5.3 V input while maintaining 5.0 V output at 1.5 A load.
Does NCV59151MN50TYG require an external resistor divider for 5.0 V output?
No, the NCV59151MN50TYG is a fixed-output device - its 5.0 V regulation is achieved internally, eliminating the need for external feedback resistors. Unlike the adjustable NCV59152 variant, this part uses internal trimming to maintain ±2% output accuracy across temperature and load, simplifying layout and reducing BOM count.
How is the error flag (FLG) pin used in NCV59151MN50TYG circuits?
The FLG pin on NCV59151MN50TYG is an open-collector output that pulls low when VOUT falls below 95% of nominal (4.75 V), with 2% hysteresis to prevent chatter. It requires an external pull-up resistor (typically 10 kΩ to VIN or 3.3 V logic rail) and can sink up to 5 mA. This signal feeds directly into MCU interrupt or status monitoring pins for real-time fault detection.
Can NCV59151MN50TYG operate with a 10 µF ceramic output capacitor?
No - the NCV59151MN50TYG requires a minimum 47 µF ceramic output capacitor (X5R/X7R) for guaranteed stability and transient response. Using 10 µF violates the datasheet's stability condition and may cause oscillation or poor load-step recovery. The 47 µF value also ensures PSRR performance remains >40 dB at 10 kHz as specified.
Is NCV59151MN50TYG pin-compatible with NCP59151MN50TYG?
Yes - NCV59151MN50TYG and NCP59151MN50TYG share identical DFN8-4x4 pinout, electrical specifications, and thermal characteristics. The only difference is automotive qualification: NCV prefix indicates AEC-Q100 Grade 1 compliance, PPAP capability, and controlled manufacturing site, while NCP is for commercial/industrial use. PCB layout and firmware are fully interchangeable.
