Product details
Overview
NCV8160BMX300TBG from onsemi is an automotive-grade ultra-low-noise, high-PSRR LDO regulator delivering 250 mA output current with 3.0 V fixed output voltage, ±2% accuracy over −40°C to +125°C, 90 mV dropout at full load, and 10 µVRMS output noise - designed for RF and analog power rails in ADAS and infotainment systems.
For engineers reviewing the NCV8160BMX300TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 Grade 1 qualification, XDFN4 1 mm × 1 mm package, active-discharge exclusion (Version B), 18 µA quiescent current, and compatibility with 1 µF ceramic input/output capacitors.
Technical Context
The NCV8160BMX300TBG employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-current protection, with integrated bandgap reference, thermal shutdown (160°C trip), and current limiting (700 mA typ.). Its enable logic uses a precise 1.2 V high-threshold and 0.4 V low-threshold to control regulation and disable state.
Unlike Version A, this B variant omits active output discharge - confirmed by "Non-Active Discharge" in the ordering table and absence of RDIS specification in electrical characteristics. It achieves 98 dB PSRR at 1 kHz and maintains stability with 0.7 µF minimum COUT, supporting fast load transients (±40 mV deviation at 200 mA step) without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40°C to +125°C - ensures stable biasing for 3.0 V analog/RF ICs without external feedback. |
| Max Output Current | 250 mA continuous - sufficient for powering multiple low-power RF receivers or sensor signal chains. |
| Dropout Voltage | 90 mV at 250 mA - enables operation from 3.1 V input, critical for battery-supplied automotive modules near EOL. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on vehicle subsystems such as telematics wake-up circuits. |
| PSRR | 98 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding sensitive ADCs or PLLs. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent spectral purity requirements for RF front-end LNA and mixer bias rails. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard 3.3 V GPIOs and supports clean sequencing in multi-rail systems. |
| Thermal Shutdown | 160°C trip / 140°C reset - protects against sustained overload in sealed enclosures without requiring external thermal monitoring. |
Pinout & Package
XDFN4 1.0 mm × 1.0 mm × 0.4 mm package with exposed thermal pad (EPAD); optimized for high-density automotive PCBs and thermal performance via GND-connected EPAD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 3.0 V; requires local 1 µF ceramic capacitor to minimize impedance and ensure transient response. |
| 2 - GND | Power ground | Reference node for regulation and thermal path; must be connected to large copper pour and EPAD for thermal relief. |
| 3 - EN | Enable control input | Logic-level interface: >1.2 V enables regulation; <0.4 V disables output and reduces IQ to 0.01 µA (no active discharge). |
| 4 - IN | Input supply | Accepts 1.9–5.5 V; internal PMOS structure prevents reverse current when VOUT > VIN. |
| EPAD | Thermal & electrical ground | Exposed pad must be soldered to PCB GND plane to achieve RJA = 198.1°C/W and sustain full 250 mA load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS output noise enables direct powering of RF LNAs and high-resolution SAR ADC references without added filtering. |
| High PSRR | 98 dB at 1 kHz and 82 dB at 10 kHz suppresses ripple from buck converters, reducing need for additional LC stages in compact modules. |
| AEC-Q100 Grade 1 | Qualified for −40°C to +125°C ambient operation - certified for under-hood and dashboard-mounted automotive electronics. |
| Low-IQ with shutdown | 18 µA operating / 0.01 µA shutdown current supports energy-efficient sleep modes in always-on telematics gateways. |
| Stable with 1 µF ceramics | No ESR requirement on COUT; eliminates need for tantalum or polymer capacitors, lowering BOM cost and improving reliability. |
| Robust protection | Integrated current limit (700 mA), short-circuit tolerance (unlimited duration), and thermal shutdown prevent field failures in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8160AMX300TBG | Includes active output discharge (280 Ω pull-down); otherwise identical specs and pinout. | Required where rapid VOUT discharge is needed after shutdown (e.g., to meet ISO 11898 bus idle timing). | Select NCV8160AMX300TBG only if active discharge is mandated; NCV8160BMX300TBG saves board space by omitting discharge circuitry. |
| TLD1120-33ES | 3.3 V output, 200 mA, higher dropout (150 mV), lower PSRR (85 dB @ 1 kHz), no enable pin. | Targeted at non-critical digital rails; lacks EN control and automotive thermal grade. | Use TLD1120-33ES only for cost-sensitive non-AEC-Q100 applications where 3.3 V and no enable are acceptable. |
Compared with NCV8160AMX300TBG, the NCV8160BMX300TBG saves power in shutdown but lacks active discharge; versus TLD1120-33ES, it delivers superior noise, PSRR, and automotive qualification - making it the only choice for safety-critical RF/analog rails.

FAQ
What is the output voltage tolerance of the NCV8160BMX300TBG over temperature?
The NCV8160BMX300TBG maintains ±2% output voltage accuracy across the full operating junction temperature range of −40°C to +125°C. This is verified per the Electrical Characteristics table and confirmed in Figure 4 (Output Voltage vs. Temperature for 3.3 V variant), with proportional behavior expected for the 3.0 V version. The NCV8160BMX300TBG achieves this using a precision bandgap reference and curvature-compensated design.
Does the NCV8160BMX300TBG include active output discharge?
No, the NCV8160BMX300TBG does not include active output discharge. As specified in the Ordering Information table, it is labeled "Non-Active Discharge" (Version B), and the Electrical Characteristics section omits RDIS parameters. Only Version A (e.g., NCV8160AMX300TBG) provides the 280 Ω discharge path when EN is low. The NCV8160BMX300TBG relies on natural discharge through load leakage.
What is the minimum output capacitance required for stability with the NCV8160BMX300TBG?
The NCV8160BMX300TBG is stable with a minimum effective output capacitance of 0.7 µF, as stated in the Applications Information section. This accounts for capacitance loss due to DC bias, temperature, and package size - especially relevant for small-case 0201/0402 MLCCs. For guaranteed performance, a 1 µF X7R/X5R ceramic capacitor placed close to the OUT pin is recommended. The NCV8160BMX300TBG imposes no ESR requirement on COUT.
Can the NCV8160BMX300TBG operate from a 3.3 V input while delivering 3.0 V at 250 mA?
Yes, the NCV8160BMX300TBG can operate from a 3.3 V input to deliver 3.0 V at 250 mA. Its typical dropout voltage is 90 mV at 250 mA (for 3.0 V output), meaning it requires only 3.09 V minimum input. At 3.3 V input, the device operates well within its 1.9–5.5 V input range and delivers full rated current with margin for line regulation (0.02%/V) and thermal rise. The NCV8160BMX300TBG's PMOS architecture ensures efficient operation in this configuration.
Is the NCV8160BMX300TBG qualified for automotive applications?
Yes, the NCV8160BMX300TBG is AEC-Q100 Grade 1 qualified and PPAP capable, as explicitly stated in the Features section and Ordering Information. It is rated for operation from −40°C to +125°C ambient temperature and designed for automotive subsystems including ADAS, infotainment, cluster, and telematics. The "NCV" prefix denotes automotive-specific process, testing, and change control - confirming its suitability for production vehicle applications. The NCV8160BMX300TBG meets all requirements for under-hood and cabin-mounted electronics.
