Product details
Overview
NCV59151MN30TYG from onsemi is an automotive-grade, 3.0 V fixed-output, 1.5 A very low-dropout (VLDO) linear regulator in a DFN8-4×4 package. It delivers ≤300 mV typical dropout at 1.5 A load, supports 2.24–13.5 V input range, features logic-compatible enable and open-collector error flag, and is AEC-Q100 qualified for use in FPGA/DSP power rails and automotive infotainment subsystems.
For engineers reviewing the NCV59151MN30TYG datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, thermal design guidance, automotive qualification status, ceramic-capacitor stability data, and validated alternative parts for functional replacement of MIC29150/MIC39150 in safety-critical point-of-load designs.
Technical Context
The NCV59151MN30TYG implements a high-precision bandgap reference with internal error amplifier and PMOS pass transistor to achieve fast transient response and stable regulation under dynamic load conditions. Its architecture includes integrated reverse output current protection and thermal shutdown triggered at +125°C junction temperature.
It operates with ceramic output capacitors ≥47 µF and requires no minimum load beyond 5 mA. The device uses a dedicated FLG pin to signal output faults when VOUT drops below 95% of nominal (2.85 V), with 2% hysteresis and guaranteed sink capability up to 5 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2.5% over −40°C to +125°C; enables direct replacement of legacy 3.0 V LDOs without resistor network redesign. |
| Dropout Voltage | 300 mV typical at 1.5 A load; allows operation with VIN as low as 3.3 V while maintaining regulation - critical for battery-backed systems. |
| Ground Current | 40–80 mA at 1.5 A load; low quiescent current preserves efficiency in always-on automotive modules. |
| Enable Threshold | 1.8 V min enable / 0.8 V max shutdown; compatible with 1.8 V/3.3 V logic without level-shifting circuitry. |
| Error Flag Threshold | 95% VOUT nominal (2.85 V) with 2% hysteresis; provides reliable undervoltage detection for system-level fault logging. |
| Thermal Shutdown | Activates at TJ = +125°C; protects against sustained overload or poor PCB heatsinking in enclosed automotive enclosures. |
| Input Voltage Range | 2.24 V to 13.5 V; supports wide-input automotive supply rails including cold-crank (≥6 V) and stop-start (≥9 V) conditions. |
Pinout & Package
NCV59151MN30TYG is housed in a thermally enhanced DFN8-4×4 mm package (Case 488AF) with exposed thermal pad connected to GND. The 8-pin layout supports compact PCB placement and efficient heat dissipation via soldered thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | EN | CMOS/TTL-compatible enable input; logic high ≥1.8 V enables regulation, logic low ≤0.8 V places device in ultra-low-IQ shutdown (≤5 µA). |
| 2 | VIN | Main input supply pin; accepts 2.24–13.5 V; must be decoupled with ≥1 µF ceramic capacitor within 1 inch of pin. |
| 3 | GND | Power ground reference; connects internally to exposed thermal pad; must be solidly tied to PCB ground plane. |
| 4 | VOUT | Regulated 3.0 V output; requires ≥47 µF ceramic capacitor at pin for stability and transient response. |
| 5 | FLG | Open-collector error flag; sinks up to 5 mA when VOUT < 2.85 V; requires external pull-up to compatible logic rail. |
| 6–7 | NC | No internal connection; electrically isolated; may be left floating or tied to GND for mechanical stability. |
| 8 | EP (Exposed Pad) | Thermal interface; must be soldered to ≥500 mm² 2 oz copper area for RJA = 75°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation with PPAP documentation support - required for ADAS and body control modules. |
| Ceramic-capacitor stability | Stable with ≥47 µF X7R/X5R ceramic output capacitor; eliminates need for tantalum or electrolytic caps and reduces board area by >50%. |
| Reverse output current protection | Withstands VOUT–VIN ≤ 6.5 V during shutdown; prevents backup battery discharge through regulator in automotive keep-alive circuits. |
| Fast transient response | Load step recovery time < 500 µs (10 mA ↔ 1.5 A); maintains tight regulation during FPGA core voltage transients. |
| Low ground current at full load | 60 mA typical IGND at 1.5 A output; improves system efficiency vs. competitors with >100 mA quiescent draw. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC29152-3.0WT | 3.0 V fixed, 1.5 A, TO-263-5 package; higher RJA (65°C/W), no error flag, non-automotive grade. | Lacks AEC-Q100 qualification and FLG pin; unsuitable for safety-critical automotive use but lower cost for industrial prototypes. | Select only for non-automotive designs where thermal margin exceeds 20°C and fault reporting is not required. |
| TPS7A4701RGWR | 3.0 V fixed, 1 A, WQFN-20; ultra-low noise (4.7 µVRMS), no enable/flag, higher cost. | Rated for 1 A only; insufficient for 1.5 A FPGA loads; optimized for RF/analog supply, not digital POL. | Choose only when sub-5 µV noise is mandatory and load current remains ≤1 A; verify thermal derating on 4-layer board. |
Compared with MIC29152-3.0WT and TPS7A4701RGWR, the NCV59151MN30TYG uniquely combines automotive qualification, 1.5 A capability, integrated fault flag, and DFN8 thermal performance - making it the sole option meeting full ASIL-B subsystem requirements for 3.0 V POL in modern vehicle ECUs.

FAQ
What is the maximum input voltage rating for NCV59151MN30TYG?
The NCV59151MN30TYG 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 even at light loads, especially in high-temperature environments. The 13.5 V upper limit ensures reliable thermal performance across the full −40°C to +125°C junction temperature range specified in the NCV59151MN30TYG datasheet.
Does NCV59151MN30TYG require an external resistor network for output voltage setting?
No, the NCV59151MN30TYG is a fixed-output 3.0 V regulator and does not require external resistors. Unlike the adjustable NCV59152 variant, this part integrates the feedback divider internally. The ADJ pin is absent - the DFN8 package contains only EN, VIN, GND, VOUT, and FLG pins plus two NC terminals and the exposed thermal pad. This simplifies layout and eliminates resistor tolerance errors affecting output accuracy in the NCV59151MN30TYG.
How does the error flag (FLG) pin function on NCV59151MN30TYG?
The FLG pin on NCV59151MN30TYG is an open-collector output that pulls low (<400 mV at 1 mA) when VOUT falls below 95% of nominal (2.85 V), with 2% hysteresis to prevent chatter. It can sink up to 5 mA and requires an external pull-up resistor to a logic-compatible voltage (e.g., 3.3 V). This flag enables real-time monitoring of regulator health in automotive ECUs, allowing host microcontrollers to log faults or initiate safe shutdown sequences before downstream ICs malfunction due to undervoltage.
Is NCV59151MN30TYG compatible with ceramic output capacitors?
Yes, the NCV59151MN30TYG is explicitly designed for stability with ceramic output capacitors ≥47 µF, as confirmed in the Applications Information section of its datasheet. It does not require ESR damping networks or tantalum/electrolytic alternatives. Using X7R or X5R 47 µF ceramics placed within 5 mm of the VOUT and GND pins ensures optimal transient response and avoids oscillation - a key advantage over older LDOs that mandate minimum ESR capacitors.
What thermal design considerations apply to NCV59151MN30TYG in DFN8 package?
For the NCV59151MN30TYG in DFN8-4×4 mm (Case 488AF), the exposed thermal pad must be soldered to ≥500 mm² of 2 oz copper for RJA = 75°C/W. Without this, junction temperature rise exceeds safe limits under 1.5 A load at ambient >70°C. Thermal vias (≥6 × 0.3 mm) should connect the pad to inner ground planes. The datasheet specifies RJC = 2.1°C/W for D2PAK variants but does not publish RJC for DFN8 - thus PCB-level heatsinking is the primary thermal path for the NCV59151MN30TYG.
