Product details
Overview
NCV8702MX30TCG from onsemi is an automotive-grade ultra-low-noise, ultra-low-quiescent-current LDO linear voltage regulator delivering 200 mA output with 3.0 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 circuitry in satellite radio receivers, rear-view cameras, and portable entertainment systems.
For engineers reviewing the NCV8702MX30TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, adaptive ground current mode (<10 µA no-load IQ), active output discharge (1 kΩ), TSOP-5 package compatibility, and stability with only 1 µF ceramic output capacitor.
Technical Context
The NCV8702MX30TCG employs a PMOS pass transistor architecture with integrated soft-start, undervoltage lockout (UVLO), thermal shutdown (160°C), and current limiting (385 mA typ). Its adaptive ground current circuit dynamically reduces quiescent current under light loads while maintaining regulation.
It features logic-level enable control (EN threshold: 0.4 V low / 0.9 V high), internal active discharge for fast turn-off, and high PSRR (68 dB @ 1 kHz) without requiring external noise-bypass capacitors - enabled by proprietary low-noise bandgap and error amplifier design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40°C to +125°C, full line/load/temperature range |
| Max Output Current | 200 mA continuous; internal current limit protects up to 385 mA (typ) |
| Dropout Voltage | 140 mV typical at 200 mA - enables operation from 3.14 V input when regulating 3.0 V |
| Quiescent Current | 10 µA typical at no load - extends battery life in always-on automotive modules |
| Output Noise | 11 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitor |
| PSRR | 68 dB @ 1 kHz - suppresses switching noise from upstream DC-DC converters |
| Enable Threshold | EN low ≤0.4 V disables regulator; EN high ≥0.9 V enables - compatible with 1.8 V/3.3 V logic |
Pinout & Package
NCV8702MX30TCG is housed in a Pb-free, RoHS-compliant TSOP-5 (Case 483) surface-mount package measuring 2.9 mm × 1.6 mm × 1.1 mm, optimized for space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.0–5.5 V; requires local 1 µF ceramic capacitor to reduce trace inductance effects |
| 2 (EN) | Logic enable input | Drives high (>0.9 V) to enable; low (<0.4 V) to disable with active output discharge |
| 3 (GND) | Power ground reference | Primary return path for IN, OUT, and internal circuits; must be low-impedance PCB plane |
| 4 (OUT) | Regulated output | Delivers stable 3.0 V; stable with ≥1 µF X5R/X7R ceramic capacitor (ESR < 700 mΩ) |
| 5 (N/C) | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise regulation | 11 µVRMS output noise without external bypass cap - critical for RF receiver power rails |
| Adaptive ground current | Reduces IQ to 10 µA at no load while maintaining regulation - ideal for always-on vehicle modules |
| Active output discharge | 1 kΩ internal pull-down discharges output in <1 ms after disable - prevents floating voltage in multi-rail systems |
| AEC-Q100 qualified | Qualified to Grade 1 (−40°C to +125°C junction) with PPAP capability - meets automotive reliability requirements |
| Stable with minimal capacitance | Guaranteed stability using only 1 µF ceramic output capacitor - reduces BOM count and board area |

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), no active discharge, SOT-23-5 package | Targeted at ultra-low-power IoT sensors, not automotive-grade; lacks AEC-Q100 qualification | Select only for non-automotive, battery-life-critical designs where noise sensitivity is secondary |
| NCP114AMX30T2G | Same 3.0 V output, 200 mA rating, and TSOP-5 package; higher IQ (45 µA), lower PSRR (55 dB @ 1 kHz) | Industrial-grade (not AEC-Q100); suitable for cost-sensitive consumer electronics, not safety-critical automotive functions | Use where automotive qualification is unnecessary and PSRR/noise performance is less critical |
Compared with TPS7A0530PDBVR and NCP114AMX30T2G, the NCV8702MX30TCG uniquely delivers AEC-Q100 Grade 1 qualification, 11 µVRMS noise, and active discharge in a TSOP-5 footprint - making it the only option meeting full automotive functional-safety power rail requirements among these three.

FAQ
What is the maximum input voltage for the NCV8702MX30TCG?
The NCV8702MX30TCG supports an absolute maximum input voltage of 6 V, with recommended operating range from 2.0 V to 5.5 V. Operation above 5.5 V risks permanent damage, while input below 1.6 V triggers undervoltage lockout (UVLO), disabling regulation until VIN rises above ~1.6 V with 100 mV hysteresis.
Does the NCV8702MX30TCG require an external noise-bypass capacitor?
No, the NCV8702MX30TCG does not require an external noise-bypass capacitor. Its internal architecture achieves 11 µVRMS output noise (100 Hz–100 kHz) without one - a key differentiator confirmed in the datasheet's Applications Information section and Typical Characteristics (Figures 3–8).
What is the purpose of Pin 5 (N/C) on the NCV8702MX30TCG TSOP-5 package?
Pin 5 on the NCV8702MX30TCG is a no-connect terminal. It is internally unconnected but may be tied to GND on the PCB to improve thermal dissipation - a practice explicitly recommended in Table 1 of the datasheet to enhance thermal resistance (θJA) performance.
How does the active output discharge function work in the NCV8702MX30TCG?
When the EN pin is driven below 0.4 V, the NCV8702MX30TCG disables regulation and activates an internal 1 kΩ pull-down resistor between OUT and GND. This discharges the output capacitor rapidly - typically within sub-millisecond timescales - preventing floating voltages that could disrupt downstream logic or cause latch-up in multi-supply systems.
Is the NCV8702MX30TCG compatible with 1.8 V logic-level enable signals?
Yes, the NCV8702MX30TCG is compatible with 1.8 V logic. Its EN pin has a guaranteed high-threshold of ≥0.9 V and low-threshold of ≤0.4 V, providing >1.4 V noise margin when driven by standard 1.8 V GPIO. The internal EN pull-down (110 nA typ) also ensures safe default-off behavior if left floating.
