Product details
Overview
NCV8154MN300300TBG from onsemi is a dual-output, 300 mA low-dropout linear voltage regulator with independent input pins, delivering precisely regulated 3.0 V / 3.0 V outputs. It features ultra-low quiescent current (55 µA per channel), high PSRR (75 dB at 1 kHz), and very low dropout (140 mV typical at 300 mA), making it ideal for powering RF-sensitive blocks in automotive infotainment systems.
For engineers reviewing the NCV8154MN300300TBG datasheet, pinout, applications, or equivalent options, key selection considerations include dual-channel enable control, wettable-flank–free DFN10 packaging, AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), and stability with 1 µF ceramic output capacitors.
Technical Context
The NCV8154MN300300TBG integrates two independent PMOS LDO regulators sharing a common ground but with separate IN1/IN2 and EN1/EN2 pins-enabling asymmetric input sourcing and independent channel sequencing. Each channel includes active discharge (50 Ω typical), thermal shutdown (160 °C trip), and current limiting (400 mA typ).
Its architecture delivers high PSRR across frequency (75 dB @ 1 kHz, >60 dB up to 100 kHz) and low RMS noise (75 µVrms, 10 Hz–100 kHz), supported by internal bandgap reference and MOSFET drivers with current-limit protection. The device operates within 1.9 V–5.25 V input range and maintains ±3% output accuracy over full temperature range for VOUT > 2 V.

|---|---|---|
| 1, 4 | GND | Power ground terminals-soldered to PCB copper plane for optimal heat dissipation and low-impedance return path |
| 2 | OUT1 | Regulated 3.0 V output; requires 1 µF ceramic capacitor to ground for stability |
| 3 | OUT2 | Regulated 3.0 V output; independently stabilized with dedicated 1 µF ceramic capacitor |
| 5, 6 | N/C | No-connect pins-may be tied to ground plane to improve thermal conduction |
| 7 | EN2 | Enable input for OUT2; >0.9 V enables, <0.4 V disables with active discharge (50 Ω) |
| 8 | IN2 | Independent input for second channel; decoupling capacitor required adjacent to pin |
| 9 | IN1 | Independent input for first channel; supports separate power domain routing |
| 10 | EN1 | Enable input for OUT1; logic-controlled turn-on/off with fast discharge capability |
| EP | Exposed Pad | Thermal and electrical ground connection-must be soldered to large GND copper area |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent inputs | Enables flexible power domain partitioning-e.g., IN1 from main 5 V rail, IN2 from isolated 3.3 V supply |
| Active output discharge | 50 Ω internal pull-down ensures rapid VOUT ramp-down (<100 µs for 1 µF load), preventing floating states during disable |
| Wettable-flank–free packaging | DFN10 variant NCV8154MN300300TBG omits wettable flanks-suitable for standard optical solder inspection without specialized AOI setup |
| AEC-Q100 Grade 1 | Qualified for automotive ambient operation from −40 °C to +125 °C-validates reliability in engine bay and infotainment head units |
| Stable with 1 µF ceramic output caps | Eliminates need for larger or higher-ESR capacitors-reduces BOM count and board space vs. legacy LDOs requiring ≥4.7 µF |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8154MW300300TBG | Identical electrical specs and pinout, but features wettable flanks for enhanced automated optical inspection (AOI) of solder joints. | Required in manufacturing lines using AOI systems calibrated for wettable-flank detection; not needed for standard X-ray or functional test. | Select MW300300TBG if AOI process mandates wettable flanks; otherwise MN300300TBG reduces process complexity. |
| TLD6512-2ES | Single-channel 500 mA automotive LDO (Infineon); no dual output, no independent enables, higher IQ (80 µA), lower PSRR (65 dB @ 1 kHz). | Suitable only when dual independent rails are not required-e.g., single-sensor modules or non-RF applications. | Choose TLD6512-2ES only for cost-sensitive single-rail designs where PSRR >70 dB and dual enable are unnecessary. |
Compared with NCV8154MW300300TBG, the NCV8154MN300300TBG offers identical regulation performance but eliminates wettable flanks-reducing manufacturing inspection overhead. Against TLD6512-2ES, it provides true dual-channel independence, superior PSRR, and lower quiescent current, justifying its use in RF-critical dual-rail systems.

FAQ
What output voltages does the NCV8154MN300300TBG provide?
The NCV8154MN300300TBG provides two fixed, independent 3.0 V outputs-OUT1 and OUT2-with ±3% accuracy over −40 °C to +125 °C ambient temperature. This dual 3.0 V configuration is factory-trimmed and not adjustable; each output is stabilized with its own 1 µF ceramic capacitor and supports up to 300 mA continuous load.
Does the NCV8154MN300300TBG support independent enable control for each output?
Yes, the NCV8154MN300300TBG features dedicated EN1 and EN2 pins that allow fully independent turn-on and turn-off sequencing of OUT1 and OUT2. Driving EN1 > 0.9 V enables OUT1; driving EN1 < 0.4 V disables it and activates active discharge. The same logic applies to EN2 and OUT2-enabling precise power-state control in multi-rail systems.
What is the thermal performance of the NCV8154MN300300TBG in its DFN10 package?
The NCV8154MN300300TBG in DFN10 (3×3 mm) has a junction-to-ambient thermal resistance (θJA) of 109 °C/W on a 1 oz FR4 PCB with 645 mm² copper area. With a maximum junction temperature of 150 °C and ambient up to +125 °C, this allows ~225 mW max power dissipation-sufficient for 300 mA at 140 mV dropout (42 mW per channel) under typical conditions.
Is the NCV8154MN300300TBG qualified for automotive applications?
Yes, the NCV8154MN300300TBG is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C ambient), PPAP-capable, and carries the NCV prefix denoting automotive-specific change control and site qualification. It includes thermal shutdown (160 °C trip), current limiting, and robust ESD protection (2 kV HBM)-meeting critical automotive reliability requirements.
Can the NCV8154MN300300TBG operate with input voltage below 2.0 V?
Yes-the NCV8154MN300300TBG supports an operating input voltage range of 1.9 V to 5.25 V. At 1.9 V input, it can still regulate 3.0 V outputs as long as the dropout condition is met (i.e., VIN ≥ VOUT + VDO). However, with VOUT = 3.0 V and typical VDO = 140 mV, minimum functional VIN is ~3.14 V; thus, 1.9 V input is only valid for lower-output variants-not the NCV8154MN300300TBG.
