Product details
Overview
NCV8702MX28TCG from onsemi is an automotive-grade ultra-low-noise, ultra-low-quiescent-current LDO linear voltage regulator delivering 200 mA output with 2.8 V fixed output voltage, 140 mV typical dropout at full load, ±2% output accuracy, and 11 µVRMS integrated noise (100 Hz–100 kHz). It powers noise-sensitive analog circuits in rear-view cameras and satellite radio receivers.
For engineers reviewing the NCV8702MX28TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 10 µA quiescent current at no load, active output discharge, thermal shutdown, and compatibility with 1 µF ceramic output capacitors without external bypass.
Technical Context
The NCV8702MX28TCG employs a PMOS pass transistor architecture with adaptive ground current control to maintain ultra-low IQ across light-load conditions. Its internal bandgap reference and soft-start circuit ensure monotonic turn-on and suppress inrush current.
It integrates undervoltage lockout (UVLO) with 1.6 V enable threshold and 100 mV hysteresis, plus active discharge via a 1 kΩ internal pull-down when disabled - critical for fast system power sequencing in automotive infotainment modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2% over −40°C to +125°C, enabling direct replacement of 2.8 V rail in camera sensor power domains. |
| Quiescent Current | Typ. 10 µA at no load - sustains battery life in always-on automotive modules like lane-change detectors. |
| Output Noise | 11 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitor in RF receiver front-ends. |
| Dropout Voltage | 140 mV typical at 200 mA - supports operation down to 3.0 V input in 3.3 V Li-ion systems with aging cells. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding imaging sensors. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V/3.3 V logic without level-shifting in multi-rail ECUs. |
| Thermal Shutdown | 160°C trip with 20°C hysteresis - protects against sustained overload in enclosed rear-camera housings. |
Pinout & Package
NCV8702MX28TCG is housed in a 6-pin XDFN 1.5 × 1.5 mm package (Case 711AE), optimized for space-constrained automotive camera modules and requiring minimal PCB real estate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply | Accepts 2.0–5.5 V; requires local 1 µF ceramic capacitor to suppress trace inductance during load transients. |
| 2 (EN) | Enable control | Logic-compatible input: >0.9 V enables regulation; <0.4 V disables with active discharge; internal 110 nA pull-down ensures safe default-off state. |
| 3 (N/C) | No-connect | Thermally isolated pad; may be tied to GND to improve thermal dissipation in high-power-density layouts. |
| 4 (OUT) | Regulated output | Delivers stable 2.8 V; stable with ≥1 µF X5R/X7R ceramic capacitor; ESR < 700 mΩ required. |
| 5 (GND) | Power ground | Primary return path; must be low-impedance connection to minimize ground bounce in high-speed imaging interfaces. |
| 6 (N/C) | No-connect | Thermally isolated pad; optional GND tie improves thermal resistance (JB = 81°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | Enables compact 2.8 V power for CMOS image sensors without adding noise-filtering components or board area. |
| Active output discharge | Pulls OUT to GND via 1 kΩ resistor when disabled - prevents floating bias in downstream ADCs or serializers during power-down sequencing. |
| Adaptive ground current | Reduces IQ to 10 µA at zero load while maintaining regulation - extends battery runtime in parked-mode camera systems. |
| AEC-Q100 qualified | Rated Grade 1 (−40°C to +125°C) with PPAP capability - meets functional safety requirements for ASIL-B automotive subsystems. |
| Stable with 1 µF ceramic COUT | Eliminates need for large bulk capacitance - reduces BOM cost and simplifies layout in tight 0402/0603 footprint designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0528PDBVR | Lower IQ (2.5 µA), but higher noise (20 µVRMS) and no active discharge; SOT-23-5 package. | Not AEC-Q100 qualified; suitable for non-automotive portable electronics only. | Select only if ultra-low IQ outweighs noise and automotive compliance requirements. |
| NCP163AMX28TBG | Same 2.8 V output and AEC-Q100 Grade 1, but higher dropout (250 mV @ 200 mA) and no active discharge. | Lacks fast turn-off capability needed for synchronized power sequencing in camera modules. | Use where thermal margin permits higher dropout and active discharge is not required. |
Compared with TPS7A0528PDBVR and NCP163AMX28TBG, the NCV8702MX28TCG uniquely combines automotive qualification, 11 µVRMS noise, active discharge, and 140 mV dropout - making it the only option meeting full design requirements for ASIL-B camera power rails.

FAQ
What is the output voltage tolerance of the NCV8702MX28TCG over temperature and load?
The NCV8702MX28TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, full 0–200 mA load range, and input voltage from VOUT + 0.3 V to 5.5 V. This is verified per Table 4 in the official datasheet and ensures stable 2.8 V bias for precision analog blocks in automotive camera ISPs without external trimming.
Does the NCV8702MX28TCG require an external noise-bypass capacitor?
No, the NCV8702MX28TCG achieves 11 µVRMS output noise (100 Hz–100 kHz) without any external bypass capacitor. Its internal architecture eliminates the need for a dedicated noise-reduction pin or external 10 nF capacitor - reducing BOM count and PCB area in space-constrained camera modules.
How does the active discharge function operate in the NCV8702MX28TCG?
When the EN pin is driven below 0.4 V, the NCV8702MX28TCG activates an internal 1 kΩ pull-down between OUT and GND, discharging the output capacitor rapidly. This ensures fast, controlled rail collapse - critical for deterministic power-down sequencing in MIPI CSI-2 camera interfaces and preventing latch-up in downstream SerDes devices.
What is the maximum input voltage the NCV8702MX28TCG can withstand?
The NCV8702MX28TCG has an absolute maximum input voltage rating of 6 V (per Table 2), but its recommended operating range is 2.0 V to 5.5 V. Exceeding 6 V risks permanent damage; for 12 V automotive systems, it must be fed from a pre-regulated 5 V domain - not directly from the battery rail.
Is the NCV8702MX28TCG compatible with 1 µF ceramic output capacitors?
Yes, the NCV8702MX28TCG is explicitly designed to be stable with a minimum 1 µF X5R or X7R ceramic capacitor (0402 or larger), as confirmed in the Applications Information section and Figure 61. Capacitor ESR must remain below 700 mΩ; tantalum types are prohibited due to high ESR and temperature sensitivity.
