Product details
Overview
NCV8154MW150330TBG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent inputs (IN1/IN2) and outputs (1.5 V / 3.3 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 NCV8154MW150330TBG datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFN10 3×3 mm), validated dual-channel enable control logic, confirmed thermal shutdown (160 °C) and active discharge (50 Ω), and AEC-Q100 Grade 1 qualification for automotive deployment.
Technical Context
The NCV8154MW150330TBG integrates two independent LDO regulators sharing a common ground but with separate input pins (IN1, IN2), EN1/EN2 enable controls, and output pins (OUT1 = 1.5 V, OUT2 = 3.3 V). Each channel features PMOS pass transistors with internal current limiting (400 mA typ.), thermal shutdown (160 °C), and active discharge circuitry activated when EN < 0.4 V.
It operates across 1.9 V to 5.25 V input range, supports stable regulation with only 1 µF ceramic output capacitors, and achieves 75 dB PSRR at 1 kHz due to high-gain error amplifiers and optimized internal compensation - critical for noise-sensitive RF blocks in automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.5 V (OUT1) and 3.3 V (OUT2) - fixed, independent, ±3% accuracy over −40 °C to +125 °C ambient. |
| Max Output Current | 300 mA per channel - sustained delivery with ≤140 mV dropout at full load for 3.3 V output. |
| Quiescent Current | 55 µA per channel (typ.) - enables >10-year battery life in always-on automotive modules. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding RF receivers. |
| Dropout Voltage | 140 mV (typ.) at 300 mA, 3.3 V output - allows operation from 3.44 V input, maximizing usable battery range. |
| Enable Thresholds | EN high = ≥0.9 V, EN low = ≤0.4 V - compatible with 1.8 V/3.3 V GPIOs without level-shifting. |
| Thermal Protection | 160 °C shutdown with 20 °C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
NCV8154MW150330TBG uses the wettable flank DFN10 3×3 mm package (Case 485C), exposing pad soldered to GND for thermal and electrical integrity. Pin functions are validated per Table 1 of the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 | GND | Power ground terminals - must be connected to large copper pour for thermal dissipation and low-noise reference. |
| 2 | OUT1 | 1.5 V regulated output - requires 1 µF X7R/X5R ceramic capacitor to GND for stability and transient response. |
| 3 | OUT2 | 3.3 V regulated output - independent of OUT1; supports simultaneous dual-rail powering of SoC I/O and core logic. |
| 5, 6 | N/C | No-connect pins - may be tied to GND plane to enhance thermal conduction without electrical impact. |
| 7 | EN2 | Enable for OUT2 - drives OUT2 ON/OFF and activates 50 Ω active discharge when pulled ≤0.4 V. |
| 8 | IN2 | Input for 3.3 V channel - accepts 1.9–5.25 V; requires local 1 µF ceramic decoupling capacitor. |
| 9 | IN1 | Input for 1.5 V channel - electrically isolated from IN2; enables flexible power sequencing and source separation. |
| 10 | EN1 | Enable for OUT1 - identical logic to EN2; allows independent startup/shutdown of 1.5 V rail (e.g., for processor core). |
| EP | Exposed Pad | Internally connected to GND - must be soldered to PCB ground plane for thermal performance (θJA = 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), enabling robust fault isolation. |
| Active output discharge | 50 Ω internal discharge path pulls OUT1/OUT2 to GND within microseconds upon disable - prevents floating voltages in safety-critical systems. |
| AEC-Q100 Grade 1 | Qualified for −40 °C to +125 °C ambient operation - meets automotive infotainment thermal and reliability requirements. |
| Wettable flank package | DFN10 with solderable side walls - enables automated optical inspection (AOI) of solder joints for zero-defect manufacturing. |
| Stable with 1 µF output cap | Eliminates need for larger, costly tantalum or polymer capacitors - reduces BOM cost and board area by >50% vs. legacy LDOs. |
