Product details
Overview
NCV59151MN28TYG from onsemi is an automotive-grade, fixed-output 2.8 V, 1.5 A very low-dropout (VLDO) linear regulator in a thermally enhanced DFN8-4×4 package. It delivers ≤300 mV typical dropout at full load, supports ceramic output capacitors ≥47 µF, and features logic-compatible enable and open-collector error flag pins. It is used for post-regulation of FPGA, DSP, and microcontroller core supplies in automotive infotainment and ADAS modules.
For engineers reviewing the NCV59151MN28TYG datasheet, pinout, applications, or equivalent options, this page provides verified technical context, validated pin functions, confirmed thermal and transient performance data, and AEC-Q100-compliant alternative options for automotive power rail design.
Technical Context
The NCV59151MN28TYG implements a high-precision bandgap reference with internal error amplifier and PMOS pass transistor to achieve stable 2.8 V output under load currents up to 1.5 A. Its fast transient response is enabled by optimized internal compensation and low output impedance, allowing it to maintain regulation during rapid load steps without external compensation.
It integrates reverse output current protection, thermal shutdown, and foldback current limiting - all active across the full −40°C to +125°C junction temperature range. The error flag asserts low when output voltage drops below 95% of nominal (2.66 V), with 2% hysteresis, and the enable input accepts TTL/CMOS logic levels with <40 µA leakage in shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2.5% over −40°C to +125°C; ensures stable core supply for 2.8 V I/O rails in automotive MCUs. |
| Max Output Current | 1.5 A continuous; supports high-current digital loads like FPGA I/O banks or camera sensor interfaces. |
| Dropout Voltage | 300 mV typical at 1.5 A; enables operation from 3.1 V input (e.g., buck converter output), minimizing power loss. |
| Ground Current | 60 mA typical at 1.5 A load; contributes directly to system efficiency and thermal budget in compact layouts. |
| PSRR | ≥60 dB at 1 kHz (IOUT = 0.5 A); suppresses switching noise from upstream DC-DC converters feeding sensitive analog subsystems. |
| Enable Threshold | 1.8 V min for enable; compatible with 1.8 V/3.3 V logic families without level-shifting circuitry. |
| Error Flag Threshold | 95% of VOUT (2.66 V) with 2% hysteresis; provides reliable undervoltage detection for system fault logging. |
Pinout & Package
NCV59151MN28TYG uses the DFN8-4×4 (Case 488AF) package with exposed thermal pad. Pin 1 is marked by a microdot or corner chamfer; the exposed pad must be soldered to a PCB ground plane for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | EN | CMOS/TTL-compatible enable input; logic high ≥1.8 V activates regulator; draws <40 µA in shutdown. |
| 2 | VIN | Main input supply pin; accepts 2.24 V to 13.5 V; connects to upstream DC-DC or battery rail. |
| 3 | GND | Analog/digital ground reference; ties internally to exposed thermal pad for low-impedance return path. |
| 4 | VOUT | Regulated 2.8 V output; requires ≥47 µF ceramic capacitor to ground for stability and transient response. |
| 5 | FLG | Open-collector error flag; sinks up to 5 mA when VOUT falls below 2.66 V; requires external pull-up resistor. |
| 6–7 | NC | No internal connection; electrically isolated; may be left unconnected or tied to GND for mechanical stability. |
| 8 | EP (Exposed Pad) | Thermal and electrical ground; must be soldered to ≥500 mm² 2 oz copper area for RJA = 75°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C TJ); certified for automotive power management in engine control, body electronics, and ADAS. |
| Ceramic capacitor stable | Stable with ≥47 µF X7R/X5R ceramic output cap; eliminates need for tantalum or electrolytic, reducing board area and failure risk. |
| Fault detection with hysteresis | Flag asserts at 95% VOUT (2.66 V) with 2% hysteresis; prevents chatter during marginal brownout conditions. |
| Reverse output current protection | Blocks reverse current flow when VIN = 0 V and VOUT > 0 V (e.g., backup battery scenarios); protects upstream sources. |
| Low ground current at full load | 60 mA typical IGND at 1.5 A output; improves overall system efficiency vs. legacy LDOs with >100 mA quiescent current. |

FAQ
What is the maximum input voltage rating for NCV59151MN28TYG?
The absolute maximum input voltage for NCV59151MN28TYG is 18 V, but its recommended operating range is 2.24 V to 13.5 V. Operation above 13.5 V is not guaranteed and may compromise reliability or parametric performance per the datasheet's Recommended Operating Conditions table.
Does NCV59151MN28TYG require an external output capacitor, and what type is recommended?
Yes, NCV59151MN28TYG requires a minimum 47 µF ceramic output capacitor (X5R or X7R dielectric) placed close to the VOUT and GND pins. This capacitor ensures stability, improves load transient response, and reduces high-frequency noise - electrolytic or tantalum capacitors are not required or recommended.
How does the error flag (FLG) pin function on NCV59151MN28TYG?
The FLG pin on NCV59151MN28TYG is an open-collector output that pulls low when VOUT drops below 95% of nominal (2.66 V), with 2% hysteresis. It can sink up to 5 mA and requires an external pull-up resistor (typically 10 kΩ to VIN or 3.3 V). It remains high during normal operation and startup.
Is NCV59151MN28TYG pin-compatible with MIC29150-2.8WT or MIC39150-2.8WS?
No, NCV59151MN28TYG is not pin-compatible with MIC29150-2.8WT (TO-263-3) or MIC39150-2.8WS (SO-8). It uses the DFN8-4×4 package with different pin count, layout, and terminal functions (e.g., dedicated EN and FLG pins). A PCB redesign is required for replacement.
What thermal performance can be expected from NCV59151MN28TYG in a standard PCB layout?
With a 500 mm² 2 oz copper thermal pad connected to the exposed EP, NCV59151MN28TYG achieves RJA = 75°C/W. At 1.5 A and 3.1 V input (0.3 V dropout), power dissipation is ~450 mW, resulting in ~34°C junction-to-ambient rise - well within the −40°C to +125°C operating range under typical ambient conditions.
