Product details
Overview
NCV8715SQ30T2G from onsemi is a 50 mA, 3.0 V fixed-output low-dropout linear voltage regulator designed for automotive and industrial applications requiring ultra-low quiescent current (max 5.8 µA), wide input range (4.0 V to 24 V), ±2% output accuracy over load/line/temperature, and integrated thermal shutdown and current limiting. It powers microcontroller I/O rails, sensor interfaces, and infotainment subsystems in harsh ambient environments.
For engineers reviewing the NCV8715SQ30T2G datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, package-validated pin functions, automotive-grade thermal behavior, real-world noise/PSRR performance at 100 kHz, and direct alternative part comparisons for design-in confidence.
Technical Context
The NCV8715SQ30T2G implements a bandgap-referenced error amplifier driving a PMOS pass transistor with internal UVLO, current-limit sensing, and thermal foldback circuitry. Its architecture enables stable regulation down to 230 mV dropout at 50 mA output while maintaining sub-6 µA ground current across full temperature range (−40°C to +125°C).
It operates without minimum ESR output capacitors and is stable with 0.47 µF–10 µF ceramic capacitors. PSRR reaches 60 dB at 100 kHz with 10 µF COUT, and output noise is 135 µVRMS (200 Hz–100 kHz) under 50 mA load - critical for noise-sensitive analog and RF subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40°C to +125°C, 0–50 mA load, 4.0–24 V input - ensures reliable logic-level supply for automotive MCUs and sensors. |
| Max Output Current | 50 mA continuous; up to 200 mA peak (SOA-limited) - supports low-power peripherals without external boost stages. |
| Quiescent Current | Max 5.8 µA over full load/temperature - enables always-on systems with multi-year battery life in telematics or ECU wake-up circuits. |
| Dropout Voltage | 250 mV typical at 50 mA (VIN = 4.0 V) - allows operation from degraded 5 V bus or 12 V battery during cold-crank conditions. |
| PSRR @ 100 kHz | 60 dB with 10 µF COUT - suppresses high-frequency switching noise from DC-DC converters feeding adjacent analog sections. |
| Output Noise | 135 µVRMS (200 Hz–100 kHz) - meets stringent requirements for audio codecs, ADC references, and precision sensor signal chains. |
| Thermal Shutdown | Activates at 170°C junction temperature with 15°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
NCV8715SQ30T2G is packaged in SC−70−5 (SC−88A), a 5-pin, 2.0 mm × 2.1 mm surface-mount package with exposed thermal pad (Case 419A). Pin 1 is marked by dot or bevel; orientation follows standard SC-70 pin 1 indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 4.0–24 V; requires ≥0.1 µF ceramic decoupling to GND for stability and transient immunity. |
| 2 (GND) | Power ground reference | Primary return path; must connect directly to low-impedance ground plane to minimize noise coupling and thermal resistance. |
| 3 (OUT) | Regulated 3.0 V output | Delivers up to 50 mA; requires ≥0.47 µF ceramic capacitor to GND for loop stability and load transient response. |
| 4 (N/C) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation but has no electrical function. |
| 5 (N/C) | No connection | Internally unconnected; same thermal option as Pin 4; no signal routing required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +125°C ambient operation - certified for engine bay, ADAS, and body control modules. |
| Ultra-low IQ | 4.7 µA typical, 5.8 µA max across full temperature/load range - enables >10-year battery life in always-on vehicle security systems. |
| Wide VIN range | Operates from 4.0 V to 24 V - accommodates 5 V rail sag, 12 V battery transients (ISO 7637-2 Pulse 4), and 24 V commercial vehicle systems. |
| No minimum ESR requirement | Stable with 0.47–10 µF X5R/X7R ceramics - eliminates need for costly tantalum or polymer capacitors and simplifies BOM. |
| Integrated protection | Thermal shutdown + current limiting - prevents latch-up or destruction during short-circuit or overheating events without external components. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73330PDBVR | 300 mA output, 4 µA IQ, 1.4 V min VIN, not AEC-Q100 qualified | Higher current capacity but lacks automotive qualification and thermal robustness above 125°C ambient | Select for non-automotive portable electronics where cost and higher IOUT outweigh qualification needs. |
| TPS7B8233QDGNRQ1 | 150 mA output, 3.5 µA IQ, 1.6 V min VIN, AEC-Q100 Grade 0 (−40°C to +150°C) | Wider temp range and lower IQ, but larger 8-pin VSSOP package and higher BOM cost | Prefer when system requires >50 mA or extended junction temperature margin beyond 125°C. |
Compared with TLV73330PDBVR and TPS7B8233QDGNRQ1, the NCV8715SQ30T2G delivers optimal balance of automotive qualification, ultra-low IQ, compact SC-70 footprint, and proven thermal reliability at 50 mA - making it ideal for space-constrained, battery-sensitive automotive modules where qualification and size are primary constraints.

FAQ
What is the maximum input voltage rating for the NCV8715SQ30T2G?
The NCV8715SQ30T2G has an absolute maximum input voltage of 24 V, with recommended operating range from 4.0 V to 24 V. Exceeding 24 V risks permanent damage per Absolute Maximum Ratings. The device maintains regulation and protection functionality across this full range, including during ISO 7637-2 load-dump transients when properly clamped externally.
Does the NCV8715SQ30T2G require an external capacitor on the output pin?
Yes, the NCV8715SQ30T2G requires a minimum 0.47 µF ceramic capacitor (X5R or X7R) from OUT to GND for stability. Larger values up to 10 µF improve line/load transient response and reduce output noise. Unlike older LDOs, it imposes no minimum ESR requirement, enabling use of low-cost, small-footprint MLCCs without risk of oscillation.
Is the NCV8715SQ30T2G pin-compatible with other variants in the NCV8715 family?
Yes, all SC-70 packaged NCV8715 variants (e.g., NCV8715SQ12T2G, NCV8715SQ33T2G) share identical pinout and footprint. Only the output voltage differs - allowing drop-in replacement during prototyping or voltage-scaling revisions without PCB changes, provided thermal and current requirements remain within 50 mA limits.
What is the thermal shutdown behavior of the NCV8715SQ30T2G?
The NCV8715SQ30T2G activates thermal shutdown at 170°C junction temperature and remains latched off until junction cools by 15°C (hysteresis). This protects against sustained overload or inadequate PCB heatsinking. Recovery is automatic upon cooling; no external reset is needed. Junction temperature is calculated using RJA = 390°C/W for SC-70 and ambient conditions.
Can the NCV8715SQ30T2G be used in non-automotive applications?
Yes, the NCV8715SQ30T2G is fully functional in industrial, medical, and consumer applications requiring its performance attributes - ultra-low IQ, wide VIN, and low noise. Its AEC-Q100 qualification adds reliability margin, though non-automotive users may consider lower-cost alternatives like TLV73330PDBVR if qualification is unnecessary.
