Product details
Overview
NCV8152MX180180TCG from onsemi is a dual-output, 150 mA low-dropout linear voltage regulator with independent 1.8 V outputs per channel, ultra-low quiescent current (50 µA/channel), 75 dB PSRR at 1 kHz, and AEC-Q100 Grade 1 qualification for automotive infotainment power rails. It delivers stable, low-noise bias to RF-sensitive blocks such as Bluetooth® and parking camera modules.
For engineers reviewing the NCV8152MX180180TCG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-channel enable control, 150 mV typical dropout at 150 mA, stability with 0.22 µF ceramic output capacitors, and thermal shutdown with 160°C trip point.
Technical Context
The NCV8152MX180180TCG integrates two independent PMOS-based LDO regulators in a single XDFN6 package, each with dedicated EN pins enabling asynchronous channel control and active discharge. Its bandgap reference and MOSFET driver architecture support tight output accuracy (±2.8% for VOUT > 2 V) across −40°C to +125°C ambient.
Each channel features current limiting (280 mA typ), thermal shutdown (160°C trip, 20°C hysteresis), and operates from 1.9 V to 5.25 V input. The device maintains stability without ESR requirements on 0.22 µF X7R/X5R ceramic output capacitors and achieves 75 dB PSRR at 1 kHz with minimal layout sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.8 V per channel, ±2.8% accuracy over −40°C to +125°C ensures reliable logic-level compliance for MCU cores and RF ICs. |
| Max Output Current | 150 mA per channel, with 280 mA current limit protects against sustained overload while maintaining regulation under transient loads. |
| Dropout Voltage | 270–420 mV at 150 mA (VOUT = 1.8 V), enabling operation down to VIN = 2.07 V - critical for battery-powered systems near end-of-life. |
| Quiescent Current | 50 µA per enabled channel, reducing standby power in always-on automotive modules like telematics and camera wake-up circuits. |
| PSRR | 75 dB at 1 kHz, suppressing ripple from noisy switching supplies upstream - essential for powering RF transceivers without added filtering. |
| Operating Temp | −40°C to +125°C ambient (Grade 1), validated for under-hood and dashboard-mounted infotainment subsystems. |
| Package | XDFN6 1.2 × 1.2 mm, 0.4 mm pitch with exposed pad - supports high-density PCB layouts and efficient thermal dissipation via GND plane soldering. |
Pinout & Package
NCV8152MX180180TCG is housed in an XDFN6 (Case 711AT) 1.2 mm × 1.2 mm, 0.4 mm pitch package with exposed thermal pad. The pad must be soldered to a GND copper plane for effective heat dissipation and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Regulated 1.8 V output channel 1 | Requires 0.22 µF ceramic capacitor to GND; supplies power to primary RF block or MCU core. |
| 2 - OUT2 | Regulated 1.8 V output channel 2 | Independent of OUT1; enables separate power domains for peripherals like sensors or interface ICs. |
| 3 - GND | Power ground reference | Common return path; exposed pad must be connected to PCB GND plane for thermal and noise performance. |
| 4 - EN2 | Enable input for channel 2 | Logic-high (>0.9 V) enables OUT2; <0.4 V disables OUT2 and activates 50 Ω active discharge to GND. |
| 5 - IN | Common input supply | Accepts 1.9–5.25 V; requires 0.22 µF ceramic capacitor placed adjacent to pin to suppress high-frequency noise. |
| 6 - EN1 | Enable input for channel 1 | Independent control of OUT1; internal 300 nA pull-down ensures safe default-off state when unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable pins | EN1/EN2 allow staggered power sequencing, selective channel shutdown, and fast turn-off via active discharge (50 Ω path to GND). |
| Stable with 0.22 µF ceramic output caps | Eliminates need for large or high-ESR tantalum capacitors - reduces BOM cost and board area in space-constrained modules. |
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures (−40°C to +125°C) and PPAP-capable - meets OEM requirements for infotainment ECUs. |
| Ultra-low noise output | 75 µVrms RMS noise (10 Hz–100 kHz) preserves signal integrity in sensitive analog/RF circuitry without external filtering. |
| Thermal shutdown with hysteresis | 160°C trip and 140°C reset (20°C hysteresis) prevents thermal cycling damage during sustained overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A202828PDBVR | Single 2.8 V output; no dual-channel capability; 250 mA rating; 16 V max input. | Not suitable for dual 1.8 V rail requirement; lacks independent enable/discharge per channel. | Select only if application requires higher voltage or single-rail simplicity. |
| NCP1117ST18T3G | Single 1.8 V output; 1 A rating; TO-220/SOT-223; no enable pin or active discharge. | Cannot replace dual-channel functionality; larger footprint; no automotive qualification. | Use only for non-automotive, high-current, single-rail legacy designs where space and enable control are not constraints. |
Compared with TPS7A202828PDBVR and NCP1117ST18T3G, the NCV8152MX180180TCG uniquely delivers matched dual 1.8 V outputs with independent enable control, AEC-Q100 Grade 1 qualification, and active discharge - making it the only viable option for space-constrained, safety-aware automotive RF power domains.

FAQ
What are the exact output voltages of the NCV8152MX180180TCG?
The NCV8152MX180180TCG provides two independent, fixed 1.8 V outputs - one on OUT1 and one on OUT2 - with ±2.8% accuracy over the full −40°C to +125°C operating temperature range. This dual 1.8 V configuration is explicitly defined in the Ordering Information table for this specific part number.
Does the NCV8152MX180180TCG support independent enable control for each output?
Yes, the NCV8152MX180180TCG features dedicated EN1 and EN2 pins that allow fully independent control of each 1.8 V output. Driving EN1 >0.9 V enables OUT1; driving EN1 <0.4 V disables OUT1 and activates its internal 50 Ω active discharge path to GND. The same applies separately to EN2/OUT2.
What is the minimum output capacitance required for stability with the NCV8152MX180180TCG?
The NCV8152MX180180TCG is stable with a minimum 0.22 µF ceramic (X5R or X7R) capacitor on each output. The datasheet confirms stability down to 0.15 µF effective capacitance, accounting for DC bias and temperature derating - making 0201/0402 0.22 µF MLCCs fully compliant.
Is the NCV8152MX180180TCG qualified for automotive applications?
Yes, the NCV8152MX180180TCG carries the NCV prefix indicating automotive qualification. It is AEC-Q100 Grade 1 certified (−40°C to +125°C ambient), PPAP-capable, and manufactured in onsemi's qualified automotive sites - meeting OEM requirements for infotainment, telematics, and camera ECU power rails.
What thermal protection features does the NCV8152MX180180TCG include?
Each channel of the NCV8152MX180180TCG includes independent thermal shutdown with a 160°C trip point and 20°C hysteresis (reset at 140°C). Overtemperature events disable only the affected channel, allowing the other 1.8 V output to remain operational - enhancing system robustness in thermally constrained enclosures.
