Product details
Overview
NCV8703MX30TCG from onsemi is an automotive-grade ultra-low-noise, ultra-low-quiescent-current LDO voltage regulator delivering 300 mA output at fixed 3.0 V with 12 µA typical IQ, 13 µVRMS noise (100 Hz–100 kHz), and 180 mV typical dropout at full load. It powers noise-sensitive RF receivers, imaging sensors, and automotive camera modules where clean, stable bias is critical.
For engineers reviewing the NCV8703MX30TCG datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 qualification, XDFN6 1.5×1.5 mm package thermal performance (θJA = 146 °C/W), active output discharge, and compatibility with 1 µF ceramic output capacitors.
Technical Context
The NCV8703MX30TCG implements a PMOS pass transistor architecture with adaptive ground current control to maintain 12 µA quiescent current across light-load conditions. Its internal soft-start limits inrush current during enable, while integrated thermal shutdown (160 °C) and current limiting (490 mA typ.) ensure robust operation under fault conditions.
It features an enable input with 0.9 V turn-on threshold and 0.4 V shutdown threshold, plus built-in undervoltage lockout (UVLO) activating below 1.6 V input. The device achieves ±2% output accuracy over load, line, and temperature (−40 °C to +125 °C) without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% - ensures precise bias for 3.0 V logic, analog sensors, and RF front-ends without external feedback. |
| Max Output Current | 300 mA continuous - supports moderate-power imaging sensors and audio processors in compact automotive modules. |
| Quiescent Current | 12 µA typ. at no load - enables multi-year battery life in always-on vehicle systems like rear-view cameras. |
| Output Noise | 13 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitors in GPS and satellite radio receivers. |
| Dropout Voltage | 180 mV typ. at 300 mA - allows operation down to 3.18 V input, compatible with aging Li-ion or 3.3 V rail droop in infotainment systems. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from adjacent DC/DC converters powering digital subsystems. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - provides noise-immune digital control using standard 3.3 V GPIO with 2 mV hysteresis. |
Pinout & Package
NCV8703MX30TCG is packaged in a 6-pin XDFN 1.5 × 1.5 mm, 0.5 mm pitch, thermally enhanced leadless package (Case 711AE) with exposed thermal pad. Pin 1 is IN; Pin 2 is EN; Pin 3 is N/C; Pin 4 is OUT; Pin 5 is GND; Pin 6 is N/C (tied to GND recommended for thermal improvement).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.0–5.5 V input; requires ≥1 µF ceramic capacitor close to pin for stability and transient immunity. |
| 2 (EN) | Logic enable control | Active-high enable: >0.9 V turns regulator on; <0.4 V forces shutdown with 120 nA supply current and active output discharge. |
| 3 (N/C) | No connection | Internally unconnected; leave floating or tie to GND per layout best practice for thermal relief. |
| 4 (OUT) | Regulated output | Delivers stable 3.0 V; requires ≥1 µF X7R/X5R ceramic capacitor placed adjacent to pin for loop stability. |
| 5 (GND) | Power ground reference | Die ground connected via lead frame; soldered to PCB copper pour for optimal thermal dissipation (θJB = 77 °C/W). |
| 6 (N/C) | No connection | Internally unconnected; tie to GND to improve thermal conduction from exposed pad to PCB plane. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 13 µVRMS (100 Hz–100 kHz) - enables direct powering of RF LNAs and high-resolution image sensors without post-regulation filtering. |
| Adaptive ground current | 12 µA IQ at zero load, rising only modestly with output current - preserves battery runtime in intermittent-sensing automotive applications. |
| Active output discharge | 320 Ω internal pull-down activated during shutdown - ensures fast, controlled VOUT decay (<1 ms for 1 µF), preventing latch-up in downstream logic. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C) with PPAP capability - meets functional safety requirements for ADAS camera and electronic mirror systems. |
| Stable with 1 µF ceramic COUT | No ESR requirement; supports 0402/0603 MLCCs - reduces BOM count and PCB area vs. legacy LDOs requiring 10–22 µF tantalum. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0530PDBVR | Lower IQ (250 nA), but higher noise (25 µVRMS) and no AEC-Q100 qualification; 300 mA output same. | Targeted at ultra-low-power portable electronics, not automotive; lacks active discharge and thermal shutdown hysteresis. | Select only for non-automotive, battery-constrained designs where lowest possible IQ outweighs noise and qualification needs. |
| NCP114AMX30T2G | Same 3.0 V output, 300 mA rating, and AEC-Q100 Grade 1, but higher IQ (45 µA) and noise (22 µVRMS); no active discharge. | Valid for cost-sensitive automotive modules where 13 µVRMS noise and fast turn-off are non-critical. | Choose when NCV8703MX30TCG's ultra-low noise and active discharge are unnecessary, and BOM cost is primary constraint. |
Compared with TPS7A0530PDBVR and NCP114AMX30T2G, the NCV8703MX30TCG uniquely combines automotive qualification, 13 µVRMS noise, 12 µA IQ, and active output discharge-making it the only option for AEC-Q100-compliant, noise-sensitive camera and radar subsystems requiring fast, controlled power sequencing.

FAQ
What is the output voltage tolerance of the NCV8703MX30TCG over temperature and load?
The NCV8703MX30TCG maintains ±2% output voltage accuracy across the full operating junction temperature range (−40 °C to +125 °C), input voltage (2.0 V to 5.5 V), and load current (0 mA to 300 mA). This is verified per Table 4 in the datasheet and ensures reliable operation in automotive environments where voltage drift must be tightly bounded for sensor and RF ICs.
Does the NCV8703MX30TCG require an external noise-bypass capacitor?
No, the NCV8703MX30TCG does not require an external noise-bypass capacitor. Its 13 µVRMS output noise (100 Hz–100 kHz) is achieved through internal design, eliminating the need for a CNR capacitor. This simplifies layout and reduces BOM count compared to legacy LDOs that mandate 10–100 nF bypass caps for noise reduction.
What is the thermal performance of the NCV8703MX30TCG in its XDFN6 package?
In the XDFN6 1.5 × 1.5 mm package, the NCV8703MX30TCG has a junction-to-board thermal resistance (θJB) of 77 °C/W and junction-to-air (θJA) of 146 °C/W on a 1 oz FR4 PCB with 645 mm² copper area. This enables sustained 300 mA operation at +85 °C ambient with proper thermal pad soldering and PCB copper pour.
How does the enable pin function on the NCV8703MX30TCG?
The EN pin on the NCV8703MX30TCG is active-high: asserting >0.9 V enables regulation and disables active discharge; pulling <0.4 V disables the LDO and activates a 320 Ω internal pull-down on OUT. An internal 110 nA pull-down ensures default-off behavior if EN is left floating, and 2 mV hysteresis prevents noise-induced oscillation.
Is the NCV8703MX30TCG compatible with 1 µF ceramic output capacitors?
Yes, the NCV8703MX30TCG is fully stable with a minimum 1 µF X5R or X7R ceramic output capacitor. The datasheet explicitly states stability down to 0.1 µF effective capacitance (accounting for DC bias and temperature effects), making it compatible with compact 0402/0603 MLCCs and eliminating reliance on larger, higher-ESR tantalum capacitors.
