Product details
Overview
NCV8154MW330330TBG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent input pins, delivering two stable 3.3 V outputs (±3% accuracy), ultra-low noise (75 µVRMS), and high PSRR (75 dB at 1 kHz). It features active output discharge, thermal shutdown, and current limiting - designed for RF-sensitive automotive infotainment power rails.
For engineers reviewing the NCV8154MW330330TBG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel independent enable control, wettable-flank DFN10 package for optical solder inspection, AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), and compatibility with 1 µF ceramic output capacitors.
Technical Context
The NCV8154MW330330TBG integrates two independent PMOS LDO regulators in a single DFN10 3×3 mm package, each with dedicated IN, EN, and OUT pins - enabling asymmetric input sourcing and channel-level power sequencing. Its bandgap reference and MOSFET driver architecture deliver tight load/line regulation (≤45 mV) and fast transient response under 300 mA step loads.
Each channel operates across 1.9 V–5.25 V input, supports 0.9 V enable threshold and 0.4 V disable threshold, and incorporates active discharge via a 50 Ω internal resistor. Thermal shutdown triggers at 160 °C with 20 °C hysteresis, and current limit is set to 400 mA (typ.) per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V / 3.3 V ±3% (for VOUT > 2 V); enables dual-rail powering of same-voltage RF ICs without external resistive dividers. |
| Max Output Current | 300 mA per channel; sufficient to power multiple RF transceivers or MCU cores with margin for peak burst loads. |
| Dropout Voltage | 140 mV typical at 300 mA (VOUT = 3.3 V); allows operation from 3.44 V input, supporting wide battery voltage range down to ~3.5 V. |
| Quiescent Current | 55 µA per channel (typ.); enables >10-year battery life in always-on automotive modules with periodic wake-up. |
| PSRR | 75 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters feeding RF front-ends. |
| Output Noise | 75 µVRMS (10 Hz–100 kHz); meets stringent spectral purity requirements for LTE/Wi-Fi/BT coexistence. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V; compatible with 1.8 V/3.3 V GPIOs and supports robust noise-immune sequencing. |
Pinout & Package
NCV8154MW330330TBG uses the wettable-flank DFN10 3×3 mm package (Case 485C), with exposed thermal pad tied to GND for enhanced heat dissipation. Pin numbering follows top-view orientation; pins 5 and 6 are NC and may be grounded for thermal improvement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Power ground; soldered to PCB copper plane for thermal conduction and low-impedance return path. |
| 2 | OUT1 | Regulated 3.3 V output; requires 1 µF ceramic capacitor to GND for stability and transient response. |
| 3 | OUT2 | Regulated 3.3 V output; independently regulated and discharged; decoupled with separate 1 µF capacitor. |
| 5, 6 | N/C | No-connect; recommended to tie to GND plane to improve thermal performance and reduce EMI coupling. |
| 7 | EN2 | Enable for OUT2; logic-high >0.9 V activates regulator; logic-low <0.4 V disables and engages active discharge. |
| 8 | IN2 | Independent input for second channel; accepts 1.9–5.25 V; requires local 1 µF ceramic bypass capacitor. |
| 9 | IN1 | Independent input for first channel; supports separate power domain routing (e.g., isolated buck converter output). |
| 10 | EN1 | Enable for OUT1; identical threshold and discharge behavior as EN2; enables independent channel sequencing. |
| EP | Exposed Pad | Thermal pad; must be soldered to GND plane for junction-to-ambient thermal resistance of 109 °C/W (JA). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs | Enables separate power domains (e.g., IN1 from main 5 V rail, IN2 from isolated 3.3 V supply), preventing cross-talk and fault propagation. |
| Active output discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND within microseconds when disabled - critical for safe power-down in multi-rail systems. |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation; validated for automotive infotainment, telematics, and ADAS camera modules. |
| Wettable flank package | DFN10 with solderable side walls enables automated optical inspection (AOI) of solder joints - essential for zero-defect automotive manufacturing. |
| Stable with 1 µF ceramic COUT | Eliminates need for large tantalum or electrolytic capacitors; reduces board area and improves reliability over temperature and lifetime. |
Applications
| Automotive Infotainment Power | Wireless Coexistence Module |
|---|---|

Use Value: AEC-Q100 Grade 1 rating ensures operation up to +125 °C ambient; 140 mV dropout enables use with aging 12 V battery-derived 3.6 V input. |
Use Scenario: Powering cellular modem and GNSS receiver in TCU, where both subsystems demand stable 3.3 V with fast turn-on/off for power cycling. IC Role / Device Role / Timing Role: Sequenced dual LDO enabling modem sleep/wake while keeping GNSS always-on; EN1/EN2 support independent control. Use Value: 55 µA quiescent current per channel minimizes standby drain; active discharge prevents back-powering during modem reset sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A8300RTJT | Single-input dual-output LDO (no independent IN pins); higher IQ (120 µA); 3.3 V/3.3 V fixed; WQFN20 package. | Lacks independent input routing; unsuitable for split-domain architectures; no wettable flanks. | Select when board space permits larger WQFN20 and dual-input separation is unnecessary. |
| MAX25210ATPA/V+T | Automotive dual LDO with 3.3 V/3.3 V outputs; 250 µA IQ; 200 mV dropout; TDFN12 package; no wettable flanks. | Higher dropout and IQ reduce efficiency in battery-backed systems; lacks AOI-compatible packaging. | Choose only if existing MAX25210 design reuse is required and wettable flank inspection is not mandated. |
Compared with TPS7A8300RTJT and MAX25210ATPA/V+T, the NCV8154MW330330TBG uniquely combines independent inputs, wettable-flank DFN10, AEC-Q100 Grade 1, and 55 µA IQ - making it optimal for new automotive designs requiring manufacturability, thermal robustness, and ultra-low standby power.
