Product details
Overview
NCV8170BMX300TCG from onsemi is an automotive-grade CMOS low-dropout (LDO) regulator delivering 3.0 V at up to 150 mA, with ultra-low quiescent current (typ. 500 nA), 190 mV typical dropout at full load, ±1% output voltage accuracy, and AEC-Q100 qualification for use in ADAS camera modules and telematics systems.
For engineers reviewing the NCV8170BMX300TCG datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (xDFN4), confirmed EN/IN/GND/OUT pin functions, thermal shutdown behavior (175°C trip), ceramic-capacitor stability (≥1 µF), and automotive-grade reliability data per AEC-Q100 Rev G.
Technical Context
The NCV8170BMX300TCG implements a CMOS-based LDO architecture with dynamic quiescent current adjustment, enabling ultra-low IQ during standby while maintaining fast transient response via internal boost circuitry. It operates across 2.2 V–5.5 V input and delivers tightly regulated 3.0 V output over −40°C to +125°C junction temperature.
It integrates active high-enable logic (EN threshold: 1.2 V min "H", 0.4 V max "L"), thermal shutdown with 25°C hysteresis, over-current protection, and stable operation with 1 µF–10 µF X5R/X7R ceramic output capacitors-no minimum ESR required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±1% (guaranteed over −40°C to +125°C; supports precision MCU core and sensor bias rails) |
| Max Output Current | 150 mA (supports single-core microcontrollers, CAN transceivers, and image sensors without derating at TJ ≤ 125°C) |
| Quiescent Current | Typ. 500 nA (enables >10-year battery life in always-on vehicle modules like keyless entry) |
| Dropout Voltage | 190 mV typ. at 150 mA (allows regulation from 3.19 V input; critical for LiFePO₄ or dual-cell alkaline systems) |
| PSRR @ 1 kHz | 47 dB (suppresses switching noise from DC-DC converters feeding the LDO input rail) |
| Thermal Shutdown | 175°C trip with 25°C hysteresis (prevents permanent damage during sustained overload or ambient overheating) |
| Input Voltage Range | 2.2 V to 5.5 V (compatible with wide-input automotive domains including cold-crank and load-dump conditions) |
Pinout & Package
NCV8170BMX300TCG is packaged in a 1 × 1 mm xDFN4 (Case 711AJ) with wettable flank terminations, optimized for automated optical inspection (AOI) and high-density automotive PCBs. The exposed pad (EPAD) is internally connected to GND for enhanced thermal performance (RJA = 250°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Power supply input | Accepts 2.2–5.5 V; requires ≥1 µF X5R/X7R ceramic decoupling close to pin |
| 2 (GND) | Ground reference | Primary return path; connects internally to EPAD for thermal conduction |
| 3 (EN) | Enable control input | Active-high logic: ≥1.2 V enables regulator; ≤0.4 V disables and activates discharge (if A-option) |
| 4 (OUT) | Regulated output | Delivers 3.0 V ±1%; stable with 1–10 µF ceramic output capacitor (no ESR requirement) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C TJ), PPAP-capable - meets automotive functional safety baseline requirements |
| Ultra-low IQ | 500 nA typical (not µA); reduces standby power loss by >95% vs. standard LDOs in always-on domains |
| Ceramic-capacitor stable | No minimum ESR required; supports compact 0402/0603 1 µF X5R/X7R caps - eliminates tantalum dependency |
| Dynamic transient boost | Improves load-step recovery (e.g., 1 mA → 50 mA) without external compensation - critical for wireless comms bursts |
| Thermal & over-current protection | Auto-recovery shutdown at 175°C with 25°C hysteresis; short-circuit limit ~195 mA - prevents field failures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73330PDBVR | 3.0 V, 300 mA, IQ = 35 µA, SOT-23-5, no AEC-Q100 | Higher IQ limits battery life; lacks automotive qualification and thermal hysteresis spec | Acceptable for non-automotive portable designs where cost > qualification |
| TPS7A0530PDQNR | 3.0 V, 200 mA, IQ = 25 µA, X2SON-4, AEC-Q100 Grade 2 (−40°C to +105°C) | Lower temp grade; 25 µA IQ is 50× higher than NCV8170BMX300TCG's 500 nA | Use when higher current or smaller footprint needed, but not for extended-temp or ultra-low-power domains |
Compared with TLV73330PDBVR and TPS7A0530PDQNR, the NCV8170BMX300TCG uniquely combines AEC-Q100 Grade 1 qualification, sub-µA quiescent current, and xDFN4 automotive packaging - making it irreplaceable for long-life, high-reliability vehicle subsystems operating continuously at 125°C junction.

FAQ
What is the output voltage tolerance of the NCV8170BMX300TCG over temperature?
The NCV8170BMX300TCG delivers 3.0 V output with ±1% accuracy across the full operating junction temperature range of −40°C to +125°C. At +25°C, the tolerance tightens to ±0.25% (2.97 V to 3.03 V), and the device maintains ±0.6% (2.94 V to 3.06 V) under worst-case automotive thermal stress - verified per AEC-Q100 test conditions.
Does the NCV8170BMX300TCG require an external resistor network for output voltage setting?
No, the NCV8170BMX300TCG is a fixed-output LDO with factory-trimmed 3.0 V regulation. It contains no feedback pins or external resistor connections; the output voltage is laser-trimmed during wafer sort and guaranteed by design and characterization testing per datasheet Section 8 (ELECTRICAL CHARACTERISTICS − VOLTAGE VERSION 3.0 V).
Can the NCV8170BMX300TCG be used with aluminum polymer or tantalum output capacitors?
The NCV8170BMX300TCG is explicitly characterized and guaranteed stable with ceramic capacitors ≥1 µF (X5R/X7R). While aluminum polymer or tantalum caps may function in some layouts, they are not validated per datasheet - and their higher ESR can degrade transient response and PSRR. Ceramic remains the only recommended type.
What is the maximum allowable input voltage for the NCV8170BMX300TCG?
The absolute maximum input voltage for the NCV8170BMX300TCG is 6.0 V, as specified in the Absolute Maximum Ratings table. However, the recommended operating input voltage range is 2.2 V to 5.5 V. Operation above 5.5 V risks permanent damage even for brief transients, and no functional guarantee is provided beyond that limit.
Is the EN pin of the NCV8170BMX300TCG 5 V tolerant?
Yes, the EN pin of the NCV8170BMX300TCG is rated for up to 6.0 V (absolute maximum), making it 5 V tolerant. The enable threshold is defined as VENH ≥ 1.2 V (for enable) and VENL ≤ 0.4 V (for disable), with leakage current limited to 10 nA across the full 0–5.5 V input range - ensuring robust interfacing with 3.3 V or 5 V GPIOs.
