onsemi NCV8560MN280R2G

Overview

NCV8560MN280R2G from onsemi is a fixed-output 2.8 V, 150 mA low-dropout (LDO) regulator in DFN6 (3×3 mm) package, featuring 150 mV dropout at full load, ±2% output voltage tolerance over −40°C to +125°C, and AEC-Q100 qualification for automotive post-regulation of noise-sensitive RF and VCO circuits.

For engineers reviewing the NCV8560MN280R2G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low dropout under high ambient temperature, fast 15 µs enable turn-on time, low 50 µV_RMS output noise without bypass capacitor, and compatibility with low-ESR ceramic output capacitors down to 1.0 µF.

Technical Context

The NCV8560MN280R2G integrates a PMOS pass transistor enabling ultra-low dropout operation, thermal shutdown at 175°C typical with 10°C hysteresis, and internal current limiting protecting against short-circuit faults. Its enable input accepts logic-level control with 0.9 V rising threshold and 0.4 V falling threshold.

Designed for automotive-grade reliability, it operates across 1.75 V to 6.0 V input range, supports stable regulation at 125°C junction temperature, and maintains ≤15 mV load regulation (1–150 mA) and ≤10 mV line regulation (1.75–6.0 V), meeting stringent SMPS post-regulation requirements.

Key Specifications

Pinout & Package

NCV8560MN280R2G uses the DFN6 (3×3 mm, 0.65 mm pitch) package with exposed thermal pad (Case 488AE), optimized for PCB heat dissipation. Pin 1 is marked by chamfered corner; EPAD must be soldered to PCB ground plane for thermal performance.

FAQ

What is the maximum input voltage for NCV8560MN280R2G?

The absolute maximum input voltage for NCV8560MN280R2G is 6.0 V, per the Absolute Maximum Ratings table. Operation above this voltage risks permanent device damage. For reliable regulation, the minimum input must be at least V_OUT + V_DO = 2.8 V + 75 mV = 2.875 V, though the datasheet specifies 1.75 V as the lower bound for valid operation - meaning the part will only regulate correctly when VIN ≥ 2.875 V under 150 mA load.

Does NCV8560MN280R2G require an external bypass capacitor for noise reduction?

No, NCV8560MN280R2G does not require an external bypass capacitor for noise reduction. Its internal design achieves 50 µV_RMS output noise (10 Hz–100 kHz) without any additional capacitor, unlike many competing low-noise LDOs that mandate external 10 nF–100 nF bypass caps and suffer slower startup times. This simplifies layout and reduces BOM count.

Is NCV8560MN280R2G pin-compatible with other variants in the NCV8560 family?

Yes, all DFN6-packaged NCV8560 variants - including NCV8560MN280R2G, NCV8560MN330R2G, and NCV8560MNADJR2G - share identical pinout and footprint (Case 488AE). The only differences are output voltage (fixed or adjustable) and marking code; no PCB redesign is needed when substituting within the same package variant.

What is the thermal resistance (R_JA) of NCV8560MN280R2G in its DFN6 package?

The thermal resistance junction-to-ambient (R_JA) for NCV8560MN280R2G in the DFN6 (3×3 mm) package is 107°C/W, measured using a 650 mm² copper heat-spreading area with 1 oz copper thickness. This value assumes proper soldering of the exposed thermal pad (EPAD) to a large PCB ground plane - omitting EPAD connection degrades thermal performance significantly.

Can NCV8560MN280R2G be used in adjustable-output configurations?

No, NCV8560MN280R2G is a fixed-output variant and does not support adjustable operation. Its ADJ pin is internally disconnected (NC), as confirmed by the PIN FUNCTION DESCRIPTION table and ordering information. For adjustable output, select NCV8560MNADJR2G - which features the same DFN6 package but with functional ADJ pin and external resistor divider capability.
