Product details
Overview
NCV8154MW150180TBG from onsemi is a dual-output, low-noise, low-IQ linear voltage regulator delivering 300 mA per channel with independent inputs (IN1/IN2) and outputs (1.5 V / 1.8 V). It features ultra-low dropout (335 mV typ. at 300 mA for 1.8 V), 75 dB PSRR at 1 kHz, and active output discharge - optimized for RF-sensitive automotive infotainment and battery-powered wireless modules.
For engineers reviewing the NCV8154MW150180TBG datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFN10 3×3 mm), confirmed dual-channel enable control, thermal shutdown behavior, wettable flank compatibility for optical inspection, and AEC-Q100 Grade 1 qualification for automotive deployment.
Technical Context
The NCV8154MW150180TBG integrates two independent PMOS LDO regulators in a single DFN10 package, each with dedicated input, enable, and output pins - enabling asymmetric supply sequencing and fault isolation. Its bandgap reference, current-limited MOSFET drivers, and active discharge circuitry support fast turn-off and robust transient response under load steps up to 300 mA.
Designed for automotive-grade reliability, it operates across −40 °C to +125 °C ambient, incorporates thermal shutdown (160 °C trip, 20 °C hysteresis), overcurrent protection (400 mA typ. limit), and ESD immunity (2 kV HBM). The device remains stable with only 1 µF ceramic output capacitance per rail and requires no minimum ESR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.5 V (OUT1) and 1.8 V (OUT2) - fixed, factory-trimmed outputs enabling direct power to mixed-voltage SoC domains. |
| Max Output Current | 300 mA per channel - supports high-current digital cores or RF transceivers without external boost stages. |
| Dropout Voltage | 335 mV typical at 300 mA for 1.8 V output - enables operation from 2.135 V input, critical for Li-ion battery discharge tails. |
| Quiescent Current | 55 µA per channel (typ.) - extends battery life in always-on automotive modules like Bluetooth gateways or telematics. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters, preserving signal integrity in RF receivers. |
| Operating Input Range | 1.9 V to 5.25 V - accommodates wide-input automotive systems and multi-cell battery configurations. |
| Thermal Shutdown | 160 °C junction trip with 20 °C hysteresis - protects against sustained overload while allowing recovery without system reset. |
Pinout & Package
NCV8154MW150180TBG uses the DFN10 3×3 mm package (Case 485C) with wettable flanks for automated optical inspection. The exposed pad (EP) must be soldered to GND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Power ground terminals - both must be connected to PCB ground plane; primary thermal path via EP. |
| 2 | OUT1 | 1.5 V regulated output - requires 1 µF ceramic capacitor to GND for stability; supplies core logic or I/O rails. |
| 3 | OUT2 | 1.8 V regulated output - independently regulated; supports memory interfaces or RF front-end biasing. |
| 5, 6 | N/C | No-connect pins - may be tied to GND to enhance thermal dissipation but carry no electrical function. |
| 7 | EN2 | Enable for OUT2 - logic-high (>0.9 V) enables 1.8 V output; <0.4 V disables with active discharge (50 Ω). |
| 8 | IN2 | Input for OUT2 - accepts 1.9–5.25 V; decoupling capacitor required close to pin for noise rejection. |
| 9 | IN1 | Input for OUT1 - independent of IN2; allows separate power domains (e.g., battery vs. ignition-supplied rail). |
| 10 | EN1 | Enable for OUT1 - identical threshold behavior to EN2; enables precise sequencing of 1.5 V domain. |
| EP | Exposed Pad | Thermal and electrical GND connection - mandatory for thermal performance; soldered to inner/outer GND planes. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs | Enables separate sourcing (e.g., IN1 from main battery, IN2 from always-on rail), preventing cross-regulation during transients. |
| Active output discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND within microseconds when disabled - prevents floating voltages in hot-swap scenarios. |
| Wettable flank package | DFN10 with solderable side walls - supports automated X-ray and AOI inspection for zero-defect automotive manufacturing. |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation - meets automotive infotainment and ADAS subsystem requirements. |
| Stable with 1 µF ceramic COUT | Eliminates need for large or high-ESR capacitors - reduces BOM cost and board area while maintaining phase margin >60°. |
Applications
| Automotive Infotainment Power | Wireless Connectivity Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7491518PWR | 1.5 V / 1.8 V outputs; 200 mA per channel; 60 dB PSRR at 1 kHz; WSON-10 package (no wettable flanks). | Lacks AEC-Q100 qualification and active discharge; lower current rating limits use in high-power RF stages. | Select when automotive qualification is not required and thermal budget permits higher dropout (220 mV @ 200 mA). |
| NCP1117ST15T3G | Single 1.5 V output; 1 A rating; TO-220/TO-263 package; no enable or active discharge; 70 dB PSRR at 120 Hz only. | Cannot replace dual-rail functionality; requires two devices plus external sequencing logic for 1.5 V/1.8 V. | Consider only for non-automotive, cost-sensitive designs where board space and sequencing complexity are secondary concerns. |
Compared with TPS7491518PWR and NCP1117ST15T3G, the NCV8154MW150180TBG uniquely combines AEC-Q100 Grade 1 compliance, wettable flank inspection support, independent dual enable control, and active discharge - making it the only drop-in solution for safety-critical automotive dual-rail LDO applications requiring zero-defect manufacturing and fast rail collapse.
