Product details
Overview
NCP565MN15T2G from onsemi is a fixed-output, low-dropout linear regulator delivering 1.5 A at 1.5 V with 0.9 V reference voltage, 0.9 V dropout at full load, and ultra-fast transient response-ideal for post-regulation in ASIC power supplies and server point-of-load applications.
For engineers reviewing the NCP565MN15T2G datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DFN6, 3×3.3 mm), thermal resistance (RJA = 176 °C/W), ground current (1.5 mA at 1.5 A), ripple rejection (85 dB @ 120 Hz), and output noise (38 µVrms).
Technical Context
The NCP565MN15T2G implements a precision bandgap reference (0.9 V ±3% over −40°C to +125°C) driving a low-impedance output stage with integrated current-limit sense and thermal shutdown circuitry. Its fast loop compensation enables stable operation with 1.0 µF–150 µF output capacitors and ESR as low as 50 mΩ.
It operates across 3.1 V to 9.0 V input range, supports fixed 1.5 V output with ±3% tolerance over full temperature and load range, and features internal protection including 3.3 A typical current limit and 160°C thermal shutdown-no external components required for basic functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±3% from −40°C to +125°C; ensures stable core voltage for low-voltage logic under thermal stress. |
| Max Output Current | 1.5 A continuous; supports high-current FPGA/ASIC core rails without derating at TA ≤ 125°C with proper PCB copper. |
| Dropout Voltage | 0.9 V (typ) at 1.5 A; enables regulation from 2.4 V input, critical for multi-rail systems with tight input margins. |
| Ripple Rejection | 85 dB @ 120 Hz; suppresses switching noise from upstream DC-DC converters in hybrid power architectures. |
| Ground Current | 1.5 mA at 1.5 A load; minimizes quiescent power loss in always-on subsystems like management controllers. |
| Output Noise | 38 µVrms (100 Hz–100 kHz); meets low-noise requirements for analog sensor interfaces and RF bias rails. |
| Thermal Shutdown | 160°C junction threshold; provides fail-safe protection during sustained overload or inadequate heatsinking. |
Pinout & Package
Package: DFN6 (3 mm × 3.3 mm, 0.95 mm height, exposed thermal pad). Pin 1 = VIN, Pin 2 = GND, Pin 3 = VOUT, Pin 4 = NC, Pin 5 = NC, Pin 6 = GND (exposed pad electrically tied to Pin 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Positive input supply; must be ≥ 2.4 V (VOUT + VDO) and ≤ 9.0 V for safe operation. |
| 2 | GND | Power ground reference; connects directly to PCB ground plane and thermal pad for optimal heat dissipation. |
| 3 | VOUT | Regulated 1.5 V output; requires ≥1.0 µF ceramic capacitor placed adjacent to pin for stability. |
| 4 | NC | No connection; floating terminal-must not be bonded or routed to any net. |
| 5 | NC | No connection; floating terminal-must not be bonded or routed to any net. |
| 6 (Exposed Pad) | GND | Thermal and electrical ground; soldered to ≥50 mm² copper area for RJA = 176 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast transient response | Sub-400 ns recovery from 10 mA ↔ 1.5 A load steps-preserves voltage margin in burst-mode processor cores. |
| Low-noise regulation | 38 µVrms output noise enables direct powering of ADC references and PLL VCO bias without extra filtering. |
| Pb-free DFN6 package | RoHS-compliant 3×3.3 mm footprint with exposed thermal pad-reduces board space vs. SOT-223 by 62%. |
| Integrated protection | Current limit (3.3 A typ), thermal shutdown (160°C), and short-circuit robustness eliminate need for external fault management. |
| Wide input range | 2.5 V to 9.0 V operating input-supports single-supply designs using 3.3 V, 5 V, or 8.4 V battery/adapter inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-15CDCYR | 1.5 A max, 1.2 V dropout at 1.5 A, SO-8 package, no adjustable option, higher ground current (5 mA). | Larger footprint, lower thermal performance (RJA ≈ 210 °C/W), less suitable for space-constrained PCBs. | Choose when legacy SO-8 layout reuse is prioritized over thermal efficiency and board area. |
| MCP1703T-1502E/MB | 250 mA max, SOT-23 package, 600 mV dropout, 120 µVrms noise-lower current, higher noise, smaller size. | Not suitable for 1.5 A loads; limited to low-power microcontrollers or sensors. | Choose only for sub-300 mA applications where ultra-small size outweighs current capability. |
Compared with TLV1117-15CDCYR and MCP1703T-1502E/MB, the NCP565MN15T2G uniquely delivers 1.5 A in a 3×3.3 mm DFN while maintaining 38 µVrms noise and 0.9 V dropout-enabling higher-density, lower-noise, and thermally optimized designs.

FAQ
What is the maximum input voltage rating for the NCP565MN15T2G?
The NCP565MN15T2G has an absolute maximum input voltage of 18 V, but its recommended operating input range is 3.1 V to 9.0 V for reliable 1.5 V output regulation. Exceeding 9.0 V may degrade long-term reliability despite surviving short-term overstress conditions.
Does the NCP565MN15T2G require external capacitors for stability?
Yes-the NCP565MN15T2G requires a minimum 1.0 µF ceramic output capacitor with ESR between 50 mΩ and 2.5 Ω. A 150 µF OSCON-type capacitor is recommended for optimal transient response, and both input and output capacitors must be placed as close as possible to their respective pins.
Is the NCP565MN15T2G pin-compatible with other NCP565 variants in DFN6 package?
No-NCP565MN15T2G uses a 6-pin DFN6 with Pins 4 and 5 as NC, whereas adjustable versions (e.g., NCP565MNADJT2G) use Pin 5 as ADJ. The pinout differs between fixed and adjustable variants; PCB layout must match the specific variant's marking diagram.
What thermal performance can be expected from the NCP565MN15T2G in a standard PCB layout?
With a 50 mm² 1 oz copper thermal pad area, the NCP565MN15T2G achieves RJA = 176 °C/W. At 1.5 A load and 25°C ambient, junction temperature rises ~264°C above ambient-so practical operation requires ≥100 mm² copper or forced airflow to stay within −40°C to +150°C TJ limits.
How does the NCP565MN15T2G handle short-circuit conditions?
The NCP565MN15T2G incorporates foldback current limiting and thermal shutdown. Under short-circuit, it limits output current to ~3.3 A (typ), then cycles into thermal shutdown at 160°C junction temperature-automatically recovering once cooled below hysteresis threshold, protecting both itself and downstream circuitry.
