Product details
Overview
NCV8154MN330180TBG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent inputs and outputs (3.3 V / 1.8 V), ultra-low quiescent current (55 µA per channel), 75 dB PSRR at 1 kHz, and 140 mV typical dropout at 300 mA - designed for RF-sensitive automotive infotainment systems requiring stable, low-noise power.
For engineers reviewing the NCV8154MN330180TBG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel enable control, wettable-flank compatibility (not applicable to this non-wettable flank variant), AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), and stability with 1 µF ceramic output capacitors.
Technical Context
The NCV8154MN330180TBG implements two independent PMOS-based LDO channels, each with dedicated input (IN1/IN2), enable (EN1/EN2), and output (OUT1/OUT2) pins - enabling asymmetric supply sequencing and independent shutdown. Its architecture integrates active discharge (50 Ω), thermal shutdown (160 °C), and current limiting (400 mA typ.) per channel.
It operates across 1.9 V to 5.25 V input range, delivers ±3% output accuracy for VOUT > 2 V, supports fast load transient response (e.g., 300 mA step in <500 ns), and maintains stability with minimal 0.33 µF effective output capacitance - validated for DFN10 3×3 mm package with exposed thermal pad tied to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3 V (OUT1) and 1.8 V (OUT2) - fixed, factory-trimmed, enabling direct powering of MCU cores and I/O rails without external feedback. |
| Max Output Current | 300 mA per channel - sufficient for RF transceivers, audio codecs, and sensor interfaces without derating at 125 °C ambient. |
| Quiescent Current | 55 µA per channel (typ.) - enables multi-week battery life in always-on automotive modules with periodic wake-up. |
| PSRR @ 1 kHz | 75 dB - suppresses switching noise from DC-DC converters upstream, critical for RF front-end signal integrity. |
| Dropout Voltage | 140 mV (typ.) at 300 mA, VOUT = 3.3 V - allows operation from 3.44 V input, supporting wide VIN tolerance in 5 V rail systems. |
| Thermal Protection | 160 °C shutdown with 20 °C hysteresis - prevents latch-up during sustained overload while permitting automatic recovery after cooling. |
| Enable Thresholds | EN high ≥0.9 V, EN low ≤0.4 V - compatible with 1.8 V/3.3 V GPIO logic without level-shifting. |
Pinout & Package
NCV8154MN330180TBG is packaged in DFN10 3×3 mm (Case 485C) with wettable-flank option excluded ('N' suffix), featuring an exposed thermal pad (EP) soldered to GND for optimal heat dissipation. Pin count: 10. Pin pitch: 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Power ground reference; both pins must be connected to PCB ground plane for EMI suppression and thermal conduction. |
| 2 | OUT1 | 3.3 V regulated output; requires 1 µF ceramic capacitor to GND for stability and transient response. |
| 3 | OUT2 | 1.8 V regulated output; independently regulated, decoupled, and sequenced via EN2. |
| 5, 6 | N/C | No-connect pins; may be tied to GND to enhance thermal performance but not electrically required. |
| 7 | EN2 | Enable for OUT2; <0.4 V disables OUT2 and activates 50 Ω active discharge to GND. |
| 8 | IN2 | Dedicated 1.8 V channel input; accepts 1.9–5.25 V; requires local 1 µF ceramic bypass capacitor. |
| 9 | IN1 | Dedicated 3.3 V channel input; independent of IN2, enabling separate power domain sourcing. |
| 10 | EN1 | Enable for OUT1; logic-compatible with microcontroller GPIO; internal 300 nA pull-down ensures safe default-off state. |
| EP | Exposed Pad | Thermal and electrical connection to GND; mandatory for thermal compliance and junction temperature control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs | Enables separate sourcing of 3.3 V and 1.8 V rails - e.g., IN1 from main 5 V bus, IN2 from low-noise 3.3 V pre-regulator - eliminating cross-talk. |
| Active output discharge | 50 Ω internal discharge path per output ensures rapid VOUT ramp-down (<200 µs for 1 µF load), preventing back-powering of downstream circuitry. |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation - meets automotive infotainment system reliability requirements without derating. |
| Stable with 1 µF ceramic COUT | Eliminates need for larger or higher-ESR capacitors, reducing BOM cost and PCB area while maintaining phase margin >45°. |
| Ultra-low noise (75 µVRMS) | Minimizes jitter in clock generators and SNR degradation in ADCs/DACs powered by either output channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8154MW330180TBG | Same silicon, wettable flank DFN10 package - improves automated optical inspection (AOI) yield in high-volume SMT lines. | Required where IPC-A-610 Class 3 visual solder joint inspection is mandated. | Select MW variant if AOI capability is needed; MN variant remains valid for functional qualification and lower-cost assembly. |
| TPS7A83A01RTJT | Single-output, 2 A LDO with 5 µVRMS noise and 45 dB PSRR at 100 kHz - no dual-channel or independent enable support. | Suitable only when one rail is needed or when external sequencing logic is acceptable. | Use only if dual-rail independence is unnecessary; NCV8154MN330180TBG provides integrated dual-channel control unavailable in TPS7A83A01RTJT. |
Compared with NCV8154MW330180TBG, the MN variant trades AOI compatibility for lower cost and identical electrical performance; compared with TPS7A83A01RTJT, it offers true dual-rail integration and automotive qualification - making it the sole drop-in solution for AEC-Q100-compliant dual-supply systems.

FAQ
What is the output voltage configuration of the NCV8154MN330180TBG?
The NCV8154MN330180TBG delivers fixed output voltages of 3.3 V on OUT1 and 1.8 V on OUT2, as indicated by the '330180' suffix in the part number. These values are factory-trimmed and do not require external resistors. Both outputs maintain ±3% accuracy over −40 °C to +125 °C ambient temperature, supporting precision analog and digital loads without recalibration.
Is the NCV8154MN330180TBG still in production?
No - the NCV8154MN330180TBG is officially marked as discontinued per onsemi's datasheet revision 12 (February 2026). However, Aetrix Electronics maintains legacy inventory and supports design continuity through last-time-buy programs, cross-reference guidance, and alternative sourcing strategies for active production ramps.
Does the NCV8154MN330180TBG support independent enable control for each output?
Yes - the NCV8154MN330180TBG features dedicated EN1 and EN2 pins, allowing full independent control of OUT1 and OUT2. Driving EN1 ≥0.9 V enables the 3.3 V rail; driving EN2 <0.4 V disables the 1.8 V rail and activates its 50 Ω active discharge path. This enables flexible power sequencing and dynamic rail gating in complex systems.
What package type does the NCV8154MN330180TBG use, and is it wettable flank?
The NCV8154MN330180TBG uses the DFN10 3×3 mm package (Case 485C) with exposed thermal pad. The 'N' in the part number denotes non-wettable flank construction, distinguishing it from the 'W' (wettable flank) variants like NCV8154MW330180TBG. This affects AOI capability but not electrical or thermal performance.
What protection features are integrated into the NCV8154MN330180TBG?
The NCV8154MN330180TBG integrates per-channel thermal shutdown (160 °C trip, 20 °C hysteresis), output current limiting (400 mA typ.), short-circuit protection (520 mA typ.), and active discharge (50 Ω). Each channel operates independently - a fault on OUT1 does not affect OUT2 regulation or enable functionality.
