Product details
Overview
NCV8570MN275R2G from onsemi is a 200 mA ultra-low-noise, high-PSRR BiCMOS LDO regulator delivering a precise 2.75 V output with 15 µVrms noise (typ), 80 dB PSRR (typ at 1 kHz), and 105 mV dropout at 150 mA - engineered for RF power amplifier biasing in automotive satellite radios and precision analog instrumentation.
For engineers reviewing the NCV8570MN275R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, DFN6 2×2.2 mm package, active discharge circuit, 1 µA max disable current, and stable operation with ≥1 µF ceramic output capacitors.
Technical Context
The NCV8570MN275R2G integrates a bipolar-based error amplifier and bandgap reference with CMOS pass transistor control to simultaneously achieve ultra-low noise and low ground current (70–220 µA across load). Its Cnoise pin provides direct access to the internal reference node, enabling external 10–100 nF capacitor filtering to reduce output noise from 20 µVrms to 15 µVrms.
It features logic-controlled enable (CE) with 0.4–1.2 V threshold, thermal shutdown at 150 °C (20 °C hysteresis), and current limiting set to 200 mA (min) - all implemented in an AEC-Q100 qualified BiCMOS process optimized for automotive-grade reliability and RF-sensitive supply integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.75 V ±2% (1 mA load); ±3% (1–200 mA load) - ensures stable bias for RF PA stages under varying current demand. |
| Output Current | 200 mA (min current limit) - supports mid-power RF amplifiers and analog signal chains without thermal derating at 85 °C. |
| Noise (10 Hz–100 kHz) | 15 µVrms (with 100 nF Cnoise) - suppresses phase noise degradation in VCOs and LNAs. |
| PSRR | 80 dB (1 kHz), 65 dB (10 kHz) - rejects switching noise from adjacent DC/DC converters in infotainment systems. |
| Dropout Voltage | 105 mV (150 mA, 2.75 V out); 150 mV (200 mA) - enables operation from 3.0 V input in battery-powered HD radio modules. |
| Enable Threshold | 0.4 V (max low), 1.2 V (min high) - compatible with 1.8 V/3.3 V GPIO without level-shifting. |
| Quiescent Current | 70 µA (1 mA load), 220 µA (200 mA load); ≤1 µA in disable - extends battery life in always-on GPS receivers. |
Pinout & Package
NCV8570MN275R2G uses the DFN6 2×2.2 mm, 0.65 mm pitch package (Case 506BA) with exposed thermal pad (EPAD) fused to GND pins 2, 5, and EPAD for enhanced thermal dissipation (RθJA = 120 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CE | Chip Enable: Active-high logic input; internal 5 MΩ pull-down; tie to Vin for always-on operation. |
| 2, 5, EPAD | GND | Power ground with fused connection - EPAD must be soldered to PCB thermal plane for thermal compliance. |
| 3 | Vin | Input voltage (2.5–5.5 V); requires 0.1 µF ceramic bypass close to pin. |
| 4 | Vout | Regulated 2.75 V output; stable with ≥1 µF ceramic capacitor (low ESR not required). |
| 6 | Cnoise | Noise reduction pin: connect 10–100 nF capacitor to GND to filter reference node and reduce output noise by 5 µVrms. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Rated for −40 °C to +125 °C junction temperature - validated for automotive infotainment and telematics ECUs. |
| Active discharge circuit | Forces rapid Vout discharge when CE is pulled low - eliminates residual voltage that could disrupt downstream RF IC sequencing. |
| Stable with low-ESR ceramics | No minimum ESR requirement for 1 µF output capacitor - simplifies layout and avoids tantalum or polymer capacitor cost/size penalties. |
| Thermal shutdown with hysteresis | Triggers at 150 °C (typ), releases at 130 °C (typ) - prevents thermal cycling damage during sustained overload in enclosed modules. |
| Pb-free DFN6 package | RoHS-compliant 2×2.2 mm footprint - reduces board area by >50% vs. TSOP-5 while improving thermal performance (RθJA 120 vs. 220 °C/W). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS799275DRVR | 200 mA, 2.75 V, 10 µVrms noise, 70 dB PSRR (1 kHz), 6-pin WSON (2×2 mm) | Lower noise but reduced PSRR; no Cnoise pin - requires higher-value output cap for same noise floor | Preferred when absolute lowest noise dominates over PSRR; not AEC-Q100 qualified. |

FAQ
What is the maximum input voltage rating for the NCV8570MN275R2G?
The NCV8570MN275R2G has an absolute maximum input voltage rating of 6 V. Operation above this level risks permanent damage. For reliable continuous operation, the recommended input range is 2.5 V to 5.5 V - ensuring proper regulation at 2.75 V output while maintaining dropout margin across temperature and load conditions. Exceeding 5.5 V may degrade PSRR and increase ground current nonlinearly.
Does the NCV8570MN275R2G require an external capacitor on the Cnoise pin?
Yes, the NCV8570MN275R2G requires an external capacitor (10 nF to 100 nF) connected between the Cnoise pin and GND to achieve its specified 15 µVrms output noise. Without this capacitor, noise rises to 20 µVrms. The capacitor directly filters the internal bandgap reference node; using 100 nF yields optimal noise reduction, while 10 nF offers faster transient response with slightly higher noise.
Is the NCV8570MN275R2G pin-compatible with other variants in the NCV8570 family?
Yes, all DFN6-packaged NCV8570 variants (e.g., NCV8570MN180R2G, NCV8570MN330R2G) share identical pinout, package dimensions, and thermal pad configuration. The only differences are output voltage and top-marking code (MV for 2.75 V). This allows drop-in replacement across voltage options without PCB redesign - provided input voltage and load requirements remain within specification.
What thermal performance can be expected from the NCV8570MN275R2G in a standard 2-layer PCB?
In a standard 2-layer PCB with 1 oz copper and 100 mm² thermal pad copper area, the NCV8570MN275R2G achieves RθJA ≈ 150 °C/W. At 200 mA load with 3.0 V input (0.25 W dissipation), junction temperature rise is ~38 °C above ambient - well below the 150 °C thermal shutdown threshold. Full derating is required above 85 °C ambient unless additional copper or airflow is added.
How does the active discharge feature of the NCV8570MN275R2G operate during power-down?
When the CE pin is driven low, the NCV8570MN275R2G activates an internal NMOS transistor between Vout and GND, discharging the output capacitor rapidly. This circuit draws power solely from Vout - ensuring <1 µA quiescent current in sleep mode. Discharge time depends on Cout value and load; with 1 µF and no load, Vout falls from 2.75 V to 0.1 V in <1 ms, preventing latch-up in downstream RF ICs during system reset sequences.
