Product details
Overview
NCV8154MW330280TBG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent IN1/IN2 inputs and fixed 3.3 V / 2.8 V outputs. It delivers ultra-low noise (75 µVRMS), high PSRR (75 dB at 1 kHz), and very low dropout (140 mV typical at 300 mA for 3.3 V output), making it ideal for powering RF blocks in automotive infotainment systems.
For engineers reviewing the NCV8154MW330280TBG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel independent enable control, wettable flank DFN10 package for automated optical inspection, AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), and stable operation with only 1 µF ceramic output capacitors per channel.
Technical Context
The NCV8154MW330280TBG integrates two fully independent LDO channels-each with dedicated input (IN1/IN2), enable (EN1/EN2), and output (OUT1/OUT2) pins-enabling separate power domain control and sequencing. Its PMOS pass transistor architecture enables low dropout and reverse-current protection via inherent body diode management.
Each channel features active output discharge (50 Ω typical), thermal shutdown (160 °C trip, 20 °C hysteresis), current limiting (400 mA typ.), and operates across 1.9 V–5.25 V input range. Stability is guaranteed with ≥0.33 µF X5R/X7R ceramic output capacitors, and the device remains functional under indefinite short-circuit conditions per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3 V (OUT1) and 2.8 V (OUT2), fixed, ±3% accuracy over −40 °C to +125 °C |
| Max Output Current | 300 mA per channel, with 400 mA current limit and independent short-circuit protection |
| Dropout Voltage | 140 mV typical at 300 mA for 3.3 V output; 160 mV typical at 300 mA for 2.8 V output |
| PSRR | 75 dB at 1 kHz, enabling clean power delivery to noise-sensitive RF circuits |
| Quiescent Current | 55 µA per channel (typ.), supporting ultra-low-power battery operation |
| Noise | 75 µVRMS (10 Hz–100 kHz), critical for analog/RF signal integrity |
| Enable Thresholds | EN high threshold = 0.9 V, EN low threshold = 0.4 V; internal 300 nA pull-down ensures default-off state |
Pinout & Package
NCV8154MW330280TBG is housed in a wettable flank DFN10 3×3 mm package (Case 485C), optimized for automated optical inspection and thermal performance. The exposed pad (EP) must be soldered to ground for effective heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 4) | Power ground reference | Two dedicated GND pins improve current return path integrity and reduce ground bounce between channels |
| OUT1 (Pin 2) | Regulated 3.3 V output | Requires 1 µF ceramic capacitor to ground; stable down to 0.33 µF accounting for DC bias/temperature effects |
| OUT2 (Pin 3) | Regulated 2.8 V output | Independent from OUT1; supports separate load transient response and sequencing |
| N/C (Pins 5, 6) | No-connect terminals | May be tied to ground plane to enhance thermal conduction without electrical impact |
| EN2 (Pin 7) | Channel 2 enable input | Drives OUT2 ON/OFF; activates active discharge (50 Ω) when <0.4 V |
| IN2 (Pin 8) | Channel 2 input supply | Independent of IN1-supports dual-rail input architectures (e.g., separate 3.3 V and 5 V sources) |
| IN1 (Pin 9) | Channel 1 input supply | Enables independent input voltage optimization per channel (e.g., lower VIN for 3.3 V output) |
| EN1 (Pin 10) | Channel 1 enable input | Provides precise sequencing control; internal 300 nA pull-down ensures safe default-off state |
| EP | Exposed thermal pad | Mandatory connection to PCB ground plane; primary thermal path for junction-to-ambient dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs (IN1/IN2) | Enables flexible power architecture-e.g., sourcing OUT1 from a low-noise 3.3 V rail and OUT2 from a higher-efficiency 5 V rail |
| Active output discharge | 50 Ω typical discharge path pulls each output to GND within microseconds upon disable, preventing floating voltages in multi-rail systems |
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures (−40 °C to +125 °C), including thermal cycling, humidity, and ESD robustness |
| Wettable flank package | Facilitates 100% automated optical inspection (AOI) of solder joints-critical for automotive production traceability |
| Stable with 1 µF ceramic output caps | Reduces BOM count and board space vs. legacy LDOs requiring ≥10 µF tantalum; supports 0402/0201 footprints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7493328DRCT | Fixed 3.3 V / 2.8 V outputs; 300 mA per channel; 70 dB PSRR @ 1 kHz; no wettable flanks; WSON-10 package | Lacks AEC-Q100 qualification and automotive temperature range; not suitable for under-hood or infotainment front-end use | Select if non-automotive industrial application requires TI ecosystem compatibility and lower cost, but does not require AOI or Grade 1 temp range |
| NCP1117ST33T3G | Single-output 3.3 V LDO; 1 A rating; no 2.8 V option; no dual enable; SOT-223 package; no wettable flanks | Cannot replace dual-rail functionality; requires two devices plus external logic for sequencing-increasing size, cost, and failure points | Only consider for cost-sensitive, non-automotive designs where dual outputs are not required and board space is unconstrained |

These values are confirmed in Table 6 of the official datasheet under the "Voltage Option" column (3328 = 3.3 V / 2.8 V).
Does the NCV8154MW330280TBG support independent input supplies for each channel?
Yes, the NCV8154MW330280TBG features two independent input pins-IN1 for the 3.3 V channel and IN2 for the 2.8 V channel-allowing separate power source routing. This is explicitly documented in the "Features" section and Figure 1 (Typical Application Schematic), and confirmed in Table 1 (PIN FUNCTION DESCRIPTION − DFN10).
Is the NCV8154MW330280TBG qualified for automotive applications?
