Product details
Overview
NCV8154MW120280TBG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent inputs (IN1/IN2) and outputs (1.2 V / 2.8 V), ultra-low quiescent current (55 µA per channel), 75 dB PSRR at 1 kHz, and 140 mV typical dropout at 300 mA - engineered for RF-sensitive automotive infotainment power rails.
For engineers reviewing the NCV8154MW120280TBG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel independent enable control (EN1/EN2), wettable-flank DFN10 package for optical solder inspection, AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), and active output discharge capability.
Technical Context
The NCV8154MW120280TBG integrates two fully independent LDO channels, each with dedicated input, enable, and output pins - enabling separate power domain control without cross-coupling. Its PMOS pass transistor architecture delivers low dropout and reverse-current protection via inherent body diode management.
Each channel features thermal shutdown (160 °C trip, 20 °C hysteresis), current limiting (400 mA typ), and active discharge (50 Ω pull-down) triggered when EN falls below 0.4 V. Stability is guaranteed with only 1 µF ceramic output capacitors per channel, eliminating need for ESR tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.2 V (OUT1) and 2.8 V (OUT2) - fixed, factory-trimmed outputs for core logic and RF bias rails |
| Max Output Current | 300 mA per channel - supports high-transient loads in infotainment SoC subsystems |
| Quiescent Current | 55 µA per channel - enables >10-year battery standby in always-on automotive modules |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding RF receivers |
| Dropout Voltage | 140 mV typical at 300 mA (VOUT = 2.8 V) - maintains regulation down to VIN = 2.94 V |
| Operating Input Range | 1.9 V to 5.25 V - compatible with 3.3 V, 2.8 V, and 5 V supply domains |
| Enable Thresholds | EN high = ≥0.9 V, EN low = ≤0.4 V - robust TTL/CMOS-compatible control with 300 nA internal pull-down |
Pinout & Package
NCV8154MW120280TBG uses the wettable-flank DFN10 3×3 mm package (Case 485C), optimized for automated optical inspection (AOI) and thermal performance via exposed pad (EP) tied to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Power ground - dual pins enhance thermal conduction and reduce ground impedance |
| 2 | OUT1 | 1.2 V regulated output - requires 1 µF ceramic capacitor to GND for stability |
| 3 | OUT2 | 2.8 V regulated output - independently regulated, no coupling to OUT1 |
| 5, 6 | N/C | No-connect - may be grounded to improve thermal dissipation |
| 7 | EN2 | Enable for OUT2 - <0.4 V disables OUT2 and activates 50 Ω active discharge |
| 8 | IN2 | Input for OUT2 - accepts 1.9–5.25 V; decouple with 1 µF ceramic capacitor |
| 9 | IN1 | Input for OUT1 - electrically isolated from IN2; supports independent supply domains |
| 10 | EN1 | Enable for OUT1 - independent control enables staggered power-up sequencing |
| EP | Exposed Pad | Thermal & electrical GND - must be soldered to PCB copper plane for thermal relief (JA = 109 °C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs | IN1 and IN2 allow separate power sources (e.g., battery vs. ignition-switched rail) for fault isolation |
| Active output discharge | 50 Ω internal pull-down per output ensures fast, controlled turn-off (<100 µs) for system-level power sequencing |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation - meets automotive infotainment thermal requirements |
| Wettable flank package | DFN10 with solderable side walls enables 100% AOI coverage for zero-defect manufacturing |
| Stable with 1 µF output cap | Eliminates need for ESR-tuned tantalum or polymer capacitors - reduces BOM count and cost |

FAQ
What output voltages does the NCV8154MW120280TBG provide?
The NCV8154MW120280TBG provides fixed, factory-trimmed output voltages of 1.2 V on OUT1 and 2.8 V on OUT2. These values are specified in the Ordering Information table (Page 16) and confirmed in the Electrical Characteristics section. Each output is independently regulated and stable across −40 °C to +125 °C ambient temperature.
Does the NCV8154MW120280TBG support independent enable control for each output?
Yes, the NCV8154MW120280TBG features dedicated EN1 and EN2 pins that allow full independent control of OUT1 and OUT2. Driving EN1 ≥0.9 V enables OUT1; driving EN1 ≤0.4 V disables OUT1 and activates its 50 Ω active discharge path. The same logic applies to EN2/OUT2 - enabling true dual-domain power sequencing.
What package type and thermal characteristics apply to the NCV8154MW120280TBG?
The NCV8154MW120280TBG uses the wettable-flank DFN10 3×3 mm package (Case 485C) with exposed pad. Its thermal resistance is JA = 109 °C/W (1 oz FR4, 645 mm² copper area). The exposed pad must be soldered to GND for effective heat dissipation and optimal thermal performance.
Is the NCV8154MW120280TBG qualified for automotive applications?
Yes, the NCV8154MW120280TBG carries the NCV prefix indicating automotive qualification. It is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C ambient), PPAP-capable, and manufactured in onsemi's IATF 16949-certified facilities - meeting stringent automotive reliability and traceability requirements.
What is the minimum output capacitance required for stability with the NCV8154MW120280TBG?
The NCV8154MW120280TBG is stable with a minimum 1 µF ceramic (X5R/X7R) output capacitor per channel. The datasheet confirms stability down to 0.33 µF effective capacitance, accounting for DC bias and temperature derating - but 1 µF is the recommended value for guaranteed performance across all conditions.
