Product details
Overview
NCV571MN09TBG from onsemi is an automotive-grade, fixed-output low-dropout linear regulator delivering 0.9 V at up to 150 mA with ultra-low 4.0 µA typical quiescent current, ±3% output voltage accuracy over 25°C, and operation across −40°C to +125°C ambient. It uses a PMOS pass transistor, supports ceramic output capacitors as low as 0.1 µF, and integrates thermal shutdown and current limiting for battery-powered instrumentation and camera modules.
For engineers reviewing the NCV571MN09TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 0.9 V output, DFN6 package with exposed pad, enable-controlled standby mode, and dropout voltage of 650 mV (typ) at 10 mA load.
Technical Context
The NCV571MN09TBG implements a PMOS-based LDO architecture with internal voltage reference, error amplifier, and protection circuits including thermal shutdown and current limit. Its enable input allows logic-level control (VTH(HI) = 1.3 V, VTH(LO) = 0.3 V), and it operates with input voltages from 0 V to 12 V.
Designed for automotive and industrial applications, the device maintains ±4% output voltage tolerance over its full −40°C to +125°C operating range and achieves stable regulation with no minimum ESR requirement-supporting ceramic, tantalum, or polymer capacitors starting at 0.1 µF.

Pinout & Package
NCV571MN09TBG is housed in a Pb-free 6-pin DFN package (Case 506BA), 2.0 mm × 2.2 mm × 0.65 mm pitch, with exposed thermal pad (EP) recommended for grounding to enhance thermal performance (RJA = 190°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Regulated 0.9 V output; requires ≥0.1 µF ceramic capacitor to ground |
| 2 | NC | No internal connection; recommended to connect to GND for noise immunity and thermal relief |
| 3 | GND | Power ground reference; must be low-impedance path to minimize noise and ensure stability |
| 4 | Enable | Active-high logic control; pulls low to disable regulator (IQ ≤ 0.1 µA); tie to VIN if unused |
| 5 | NC | No internal connection; recommended to connect to GND |
| 6 | VIN | Positive supply input (0–12 V); requires local 0.1 µF decoupling capacitor |
| EP | Exposed Pad | Thermal and electrical connection; must be soldered to PCB GND plane for optimal thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Automotive-grade reliability with PPAP capability and unique site/control change requirements |
| Ultra-Low IQ | 4.0 µA typical enables multi-year battery life in always-on sensor nodes and telematics modules |
| Stable with Ceramic Capacitors | No ESR requirement allows use of compact, low-cost 0.1 µF X5R/X7R MLCCs without risk of oscillation |
| Wide Input Range | Supports direct connection to 12 V automotive rails or multi-cell Li-ion batteries without pre-regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8170ASN090T1G | Higher IQ (25 µA typ), same 0.9 V output, TSOP-5 package, lower max IOUT (100 mA) | Limited to lower-current applications; lacks AEC-Q100 Grade 0 qualification | Choose when board space permits TSOP-5 and 100 mA suffices; not suitable for Grade 0 automotive |
| TPS7A0509PDBVR | Lower IQ (250 nA typ), same 0.9 V, SOT-23-5 package, higher dropout (750 mV @ 100 mA) | Optimized for ultra-low-power IoT; not AEC-Q100 qualified or automotive-graded | Prefer for battery life-critical consumer wearables; avoid where automotive qualification or thermal performance is mandatory |
Compared with NCV571MN09TBG, NCV8170ASN090T1G offers simpler layout but sacrifices current capability and automotive compliance, while TPS7A0509PDBVR delivers nanoscale quiescent current at the cost of dropout voltage and qualification-making NCV571MN09TBG the only option meeting AEC-Q100 Grade 0, 150 mA, and 0.9 V simultaneously in DFN6.

FAQ
Is NCV571MN09TBG still in active production?
No, NCV571MN09TBG has been officially marked as discontinued by onsemi per Revision 6 of the datasheet (November 2025). However, Aetrix Electronics maintains secured inventory and provides lifecycle coordination support-including last-time buy planning and cross-reference guidance-for customers sustaining legacy designs that depend on this part.
What is the correct pin configuration for NCV571MN09TBG in the DFN6 package?
The NCV571MN09TBG DFN6 pinout is: Pin 1 = VOUT, Pin 2 = NC (connect to GND), Pin 3 = GND, Pin 4 = Enable, Pin 5 = NC (connect to GND), Pin 6 = VIN, with EP = exposed thermal pad (connect to GND). This matches Case 506BA mechanical drawing and is confirmed in the "PIN CONNECTIONS" section of the onsemi datasheet.
Can NCV571MN09TBG be used with a 0.1 µF output capacitor?
Yes, NCV571MN09TBG is explicitly characterized and guaranteed stable with a minimum 0.1 µF ceramic output capacitor-no ESR requirement applies. This is verified in the datasheet's "APPLICATIONS INFORMATION" section and enables compact, low-cost decoupling in space-constrained automotive and portable designs.
Does NCV571MN09TBG support enable functionality, and what are the threshold voltages?
Yes, NCV571MN09TBG features an active-high Enable pin with VTH(HI) = 1.3 V (output turns on) and VTH(LO) = 0.3 V (output turns off), as specified in the Electrical Characteristics table. When unused, the Enable pin must be tied to VIN; floating is not permitted.
What is the maximum power dissipation of NCV571MN09TBG at 25°C ambient?
At 25°C ambient and using the DFN6 package on a standard 1 oz copper PCB (100 mm²), NCV571MN09TBG has RJA = 190°C/W. With a maximum junction temperature of +150°C, the theoretical maximum power dissipation is (150 − 25)/190 ≈ 658 mW-though practical limits are governed by dropout voltage, load current, and thermal layout integrity.
