Product details
Overview
NCP59151MN28TYG from onsemi is a fixed-output, 2.8 V, 1.5 A very low-dropout (VLDO) linear regulator in DFN8-4×4 package, featuring 300 mV typical dropout at full load, ±2% output voltage accuracy over temperature and load, and logic-compatible enable/flag pins for system-level power sequencing and fault monitoring in FPGA/DSP point-of-load applications.
For engineers reviewing the NCP59151MN28TYG datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, confirmed automotive-grade alternatives, and supply-chain-ready availability details - all grounded in onsemi's official NCP59150 series documentation.
Technical Context
The NCP59151MN28TYG implements a high-precision bandgap reference with internal error amplifier and PMOS pass transistor, enabling stable regulation with ceramic output capacitors ≥47 µF. Its fast transient response stems from optimized loop compensation and low output impedance across 10 Hz–1 MHz.
It integrates CMOS/TTL-compatible enable input (1.8 V threshold), open-collector error flag (active-low, 95% VOUT trip point), reverse output current protection, thermal shutdown, and foldback current limiting - all operating within −40°C to +125°C junction range and up to 13.5 V input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2% over −40°C to +125°C and 10 mA–1.5 A load - ensures stable core voltage for 2.8 V I/O rails in FPGAs and microcontrollers. |
| Dropout Voltage | 300 mV typical at 1.5 A - enables operation with only 3.1 V input for 2.8 V output, critical for battery-powered or post-regulation systems. |
| Ground Current | 40–80 mA at 1.5 A load - directly impacts total system efficiency; lower than legacy MIC29150 (120 mA typical). |
| PSRR | ≥60 dB at 1 kHz (IOUT = 0.5 A) - suppresses switching noise from upstream DC-DC converters in mixed-signal designs. |
| Enable Threshold | 1.8 V (enable), 0.8 V (shutdown) - compatible with 1.8 V/3.3 V logic without level-shifting. |
| Error Flag Trip | 95% of nominal VOUT (2.66 V), 2% hysteresis - provides reliable undervoltage detection before downstream logic fails. |
| Thermal Shutdown | Activates at TJ ≥ +125°C - protects against sustained overload or poor PCB heatsinking in enclosed industrial enclosures. |
Pinout & Package
Package: DFN8-4×4 mm, exposed thermal pad (EP), RoHS-compliant Pb-free. Thermal resistance RJA = 75°C/W with 500 mm² 2 oz copper spread area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | EN | CMOS/TTL-compatible enable input; pull high ≥1.8 V to activate regulator; draws ≤40 µA in shutdown. |
| 2 | VIN | Main input supply (2.24–13.5 V); connects to upstream DC-DC or battery; requires ≥1 µF local bypass. |
| 3 | GND | Power ground reference; ties to EP; must be low-impedance connection to minimize noise coupling. |
| 4 | VOUT | Regulated 2.8 V output; drives load up to 1.5 A; requires ≥47 µF ceramic capacitor for stability. |
| 5 | FLG | Open-collector error flag; sinks up to 5 mA when VOUT < 2.66 V; requires external pull-up to VIN or logic rail. |
| 6–7 | NC | No internal connection; electrically isolated; may be left floating or tied to GND for mechanical stability. |
| 8 | EP | Exposed thermal pad; must be soldered to solid GND plane for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with ceramic capacitors | Eliminates need for costly tantalum or aluminum electrolytics; supports compact, high-reliability layouts with 47 µF X7R/X5R MLCCs. |
| Fast transient response | Delivers <500 µs startup time and minimal undershoot/overshoot during 100 mA–1.5 A load steps - essential for FPGA core voltage recovery. |
| Reverse output current protection | Blocks >6.5 V reverse bias (VOUT–VIN) during shutdown - prevents backup battery discharge through regulator in hot-swap or dual-rail systems. |
| AEC-Q100 qualified variant available | NCV59151MN28TYG meets automotive stress testing (Grade 1: −40°C to +125°C), enabling use in ADAS camera modules and infotainment power rails. |
| Low ground current at full load | 60 mA typical IGND at 1.5 A - reduces total input power by ~90 mW vs. older LDOs, lowering thermal load in dense PCBs. |
Applications
| Industrial PLC I/O Module | FPGA Core Power Supply |

FAQ
What is the maximum input voltage rating for NCP59151MN28TYG?
The absolute maximum input voltage for NCP59151MN28TYG is 18 V, but the recommended operating range is 2.24 V to 13.5 V. Exceeding 13.5 V risks violating safe operating area limits and may trigger thermal shutdown prematurely. The 18 V rating applies only under short-duration transient conditions per the Absolute Maximum Ratings table.
Does NCP59151MN28TYG require an external resistor divider for output voltage setting?
No, NCP59151MN28TYG is a fixed-output 2.8 V regulator and does not require an external resistor divider. It uses an internal feedback network; the ADJ pin is absent in this variant. Only adjustable versions like NCP59152 use external resistors - NCP59151MN28TYG connects directly to load with no configuration needed.
Can NCP59151MN28TYG operate with a 3.0 V input supply?
Yes, NCP59151MN28TYG can operate with a 3.0 V input because its typical dropout voltage is 300 mV at 1.5 A, leaving 2.7 V at VOUT - within the ±2% tolerance (2.744–2.856 V). At lighter loads, dropout drops further, ensuring reliable regulation even with tight input margins.
What is the purpose of the FLG pin on NCP59151MN28TYG?
The FLG pin on NCP59151MN28TYG is an open-collector error flag that pulls low when output voltage falls below 95% of nominal (2.66 V), indicating undervoltage or overload. It sinks up to 5 mA and requires an external pull-up resistor; this signal enables host MCU fault logging or graceful system shutdown before logic failure.
Is NCP59151MN28TYG pin-compatible with other devices in the NCP59150 series?
NCP59151MN28TYG shares the same DFN8-4×4 pinout with all fixed-voltage NCP59151 variants (e.g., NCP59151MN25TYG, NCP59151MN33TYG) and the adjustable NCP59152MNADJTYG - enabling footprint reuse across output voltages. However, it is not pin-compatible with D2PAK-5 versions due to differing pin count and layout.
