Product details
Overview
NCV8154MW180250TBG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent inputs (IN1/IN2) and outputs (1.8 V / 2.5 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 NCV8154MW180250TBG datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFN10 3×3 mm), validated dual-channel enable control logic, confirmed wettable flank feature, and AEC-Q100 Grade 1 thermal performance (−40 °C to +125 °C).
Technical Context
The NCV8154MW180250TBG integrates two independent PMOS LDO regulators sharing a common ground but featuring separate input pins (IN1, IN2), enable pins (EN1, EN2), and output pins (OUT1, OUT2), enabling asynchronous power sequencing and isolation between 1.8 V and 2.5 V domains. Each channel includes dedicated active discharge (50 Ω), thermal shutdown (160 °C), and current limit (400 mA typ).
Its architecture supports stable operation with only 1 µF ceramic output capacitors per rail and achieves 75 dB PSRR at 1 kHz due to high-gain error amplifiers and optimized internal compensation - critical for noise-sensitive RF blocks like Bluetooth® and ZigBee® transceivers in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.8 V (OUT1) and 2.5 V (OUT2) - fixed, factory-trimmed outputs with ±3% accuracy over −40 °C to +125 °C. |
| Max Output Current | 300 mA per channel - sustained delivery with <140 mV dropout at full load ensures minimal headroom loss in low-voltage systems. |
| Quiescent Current | 55 µA per channel (typ.) - enables multi-week battery life in always-on automotive modules without compromising regulation. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters, preserving signal integrity in RF receivers. |
| Dropout Voltage | 140 mV (typ.) at 300 mA for 1.8 V output - allows operation from 2.0 V input, supporting wide VIN range (1.9 V–5.25 V). |
| Enable Threshold | EN high = 0.9 V, EN low = 0.4 V - compatible with 1.8 V and 3.3 V logic families for flexible microcontroller control. |
| Thermal Protection | 160 °C shutdown with 20 °C hysteresis - prevents latch-up during transient overload while maintaining second-channel operation. |
Pinout & Package
NCV8154MW180250TBG uses the DFN10 3×3 mm wettable flank package (Case 485C), with exposed thermal pad (EP) soldered to GND for enhanced heat dissipation. Pin functions are validated per Table 1 of the official datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Power ground terminals - must be connected to large copper pour for thermal and EMI performance. |
| 2 | OUT1 | 1.8 V regulated output - requires 1 µF X7R/X5R ceramic capacitor to GND for stability. |
| 3 | OUT2 | 2.5 V regulated output - independently regulated; decoupling capacitor must be placed adjacent to pin. |
| 5, 6 | N/C | No-connect pins - may be tied to GND plane to improve thermal conduction. |
| 7 | EN2 | Enable for OUT2 - drives high (>0.9 V) to activate; pulls low (<0.4 V) to disable with active discharge. |
| 8 | IN2 | Input for 2.5 V channel - requires local 1 µF ceramic capacitor to minimize input impedance. |
| 9 | IN1 | Input for 1.8 V channel - electrically isolated from IN2 to prevent cross-coupling in mixed-rail systems. |
| 10 | EN1 | Enable for OUT1 - independent control enables staggered power-up sequences. |
| EP | Exposed Pad | Thermal pad - must be soldered to GND plane; accounts for >70% of total thermal resistance reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs | IN1 and IN2 allow separate power domains (e.g., 1.8 V rail from LDO, 2.5 V rail from DC-DC), eliminating coupling-induced noise. |
| Active output discharge | 50 Ω internal discharge path per output - ensures fast, controlled turn-off (<100 µs for 1 µF load), preventing floating voltages in safety-critical systems. |
| Wettable flank package | DFN10 with solderable side walls - enables automated optical inspection (AOI) of solder joints, improving manufacturing yield in automotive PCB assembly. |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation - meets automotive infotainment thermal requirements without derating. |
| Stable with 1 µF output cap | No ESR requirement - simplifies BOM by eliminating need for specialized low-ESR tantalum or polymer capacitors. |
Applications
| Automotive Infotainment Power | Wireless Coexistence Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A202818PDBVR | Single-input dual-output (shared IN), no wettable flank, lower PSRR (65 dB @ 1 kHz), 200 mA per channel. | Lacks independent inputs and automotive qualification - suitable for consumer portable devices only. | Choose only if board space is constrained and AEC-Q100 is not required; verify thermal margin with 207 °C/W JA (WDFN6). |
| NCP1117ST18T3G | Single-output, 1 A, TO-220/SOT-223, no enable, no active discharge, 1.2 V dropout at 800 mA. | Requires two discrete parts to match dual-rail function; lacks sequencing, wettable flank, and PSRR performance. | Use only for cost-sensitive non-automotive designs where size and noise immunity are secondary to BOM simplicity. |
Compared with TPS7A202818PDBVR and NCP1117ST18T3G, the NCV8154MW180250TBG uniquely delivers independent input rails, AEC-Q100 Grade 1 qualification, wettable flank inspection capability, and 75 dB PSRR - making it the only option qualified for automotive RF power domains requiring simultaneous 1.8 V/2.5 V regulation with fault isolation.

FAQ
What output voltages does the NCV8154MW180250TBG provide?
The NCV8154MW180250TBG provides fixed, factory-trimmed output voltages of 1.8 V on OUT1 and 2.5 V on OUT2. These values are specified in the Ordering Information table (Page 16) and confirmed in electrical characteristics testing across −40 °C to +125 °C. Output accuracy is ±3% for VOUT > 2 V, ensuring reliable operation for modern low-voltage logic and RF ICs.
Does the NCV8154MW180250TBG support independent enable control for each output?
Yes, the NCV8154MW180250TBG features dedicated EN1 and EN2 pins that independently control OUT1 and OUT2. Driving EN1 > 0.9 V enables the 1.8 V output; driving EN2 > 0.9 V enables the 2.5 V output. Each channel also activates active discharge when its respective EN pin falls below 0.4 V - a key feature for safe power-down sequencing in automotive systems.
What package type and thermal characteristics apply to the NCV8154MW180250TBG?
The NCV8154MW180250TBG uses the DFN10 3×3 mm wettable flank package (Case 485C) with an exposed thermal pad. Its junction-to-air thermal resistance (θJA) is 109 °C/W on a 1 oz FR4 board with 645 mm² copper area. This package enables AOI-compatible solder joints and supports continuous 300 mA operation within AEC-Q100 Grade 1 ambient limits when properly mounted.
Is the NCV8154MW180250TBG qualified for automotive applications?
Yes, the NCV8154MW180250TBG carries the NCV prefix indicating automotive qualification. It is AEC-Q100 Grade 1 certified (−40 °C to +125 °C ambient), PPAP-capable, and manufactured in onsemi's IATF 16949-certified facilities. The device includes thermal shutdown, current limiting, and robust ESD protection (2 kV HBM) required for automotive infotainment deployment.
Can the NCV8154MW180250TBG operate with ceramic output capacitors smaller than 1 µF?
The NCV8154MW180250TBG is characterized for stability with ≥1 µF X7R/X5R ceramic capacitors. While the datasheet notes minimum effective capacitance of 0.33 µF (accounting for DC bias and temperature effects), using smaller values risks instability and degraded transient response. For 0201-size capacitors, derating due to DC bias must be verified - the recommended 1 µF value ensures guaranteed stability across all operating conditions.
