Product details
Overview
NCV8715SQ12T2G from onsemi is a 50 mA ultra-low-quiescent-current LDO linear voltage regulator delivering a fixed 1.2 V output, operating from 2.5 V to 24 V input, with ±2% output accuracy over full load, line, and temperature (−40°C to +125°C), thermal shutdown, and current limiting - used in automotive infotainment power rails requiring stable low-noise bias.
For engineers reviewing the NCV8715SQ12T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 4.7 µA typical ground current at full load, 260–450 mV dropout at 50 mA, 60 dB PSRR at 100 kHz, 65 µVRMS output noise (200 Hz–100 kHz), and AEC-Q100 Grade 1 qualification for under-hood automotive use.
Technical Context
The NCV8715SQ12T2G integrates a bandgap reference, MOSFET driver with current limiting, UVLO, and thermal shutdown circuitry in a single SC-70-5 (SC-88A) package. Its internal architecture enables stable regulation without minimum ESR output capacitors and supports ceramic capacitors as low as 0.47 µF.
It operates across an extended ambient temperature range of −40°C to +125°C, with junction temperature limited to 150°C maximum and thermal shutdown triggered at 170°C with 15°C hysteresis - ensuring robustness in automotive safety-critical subsystems where input transients and thermal cycling are common.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2% over −40°C to +125°C, 0–50 mA load, and 3.0–24 V input - ensures precise core/bias rail for low-voltage MCUs and sensors. |
| Quiescent Current | Max 5.8 µA over full load and temperature - enables >10-year battery life in always-on automotive modules. |
| Dropout Voltage | 260–450 mV at 50 mA (VIN = 3.5 V) - allows operation from degraded 12 V systems down to ~1.46 V headroom. |
| PSRR | 60 dB at 100 kHz - suppresses high-frequency switching noise from upstream DC-DC converters feeding infotainment SoCs. |
| Noise | 65 µVRMS (200 Hz–100 kHz) - meets stringent analog audio supply requirements without additional filtering. |
| Thermal Shutdown | 170°C activation with 15°C hysteresis - prevents latch-up during sustained overload or poor PCB heatsinking. |
| Package | SC-70-5 (SC-88A), 1.6 mm × 1.6 mm × 0.9 mm - enables compact placement near noise-sensitive loads. |
Pinout & Package
SC-70-5 (SC-88A) package: 5-pin surface-mount, 1.6 mm × 1.6 mm body, 0.9 mm height, 0.65 mm pitch, Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.5–24 V; requires ≥0.1 µF ceramic decoupling to GND for stability and transient immunity. |
| 2 (N/C) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation - no electrical function. |
| 3 (GND) | Power ground reference | Primary return path; must be low-impedance and routed wide/short to minimize noise coupling into regulation loop. |
| 4 (N/C) | No connection | Internally unconnected; optional GND tie for thermal enhancement - no signal or bias role. |
| 5 (OUT) | Regulated 1.2 V output | Delivers up to 50 mA; requires ≥0.47 µF ceramic capacitor to GND for phase margin and load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation - suitable for engine control, ADAS camera modules, and body electronics. |
| Ultra-low ground current | 4.7 µA typical at full 50 mA load - reduces system standby power by >90% vs. legacy LDOs in always-on gateways. |
| No minimum ESR requirement | Stable with 0.47–10 µF X5R/X7R ceramics - eliminates need for costly tantalum or polymer capacitors. |
| Wide input voltage range | 2.5–24 V operation - accommodates cold-crank (≥4.5 V), load-dump (≤24 V), and dual-battery (24 V nominal) vehicle architectures. |
| Integrated protection | Thermal shutdown + current limiting - prevents damage during short-circuit or PCB trace overheating without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B8233QDGNRQ1 | 330 mA output, 2.5 µA IQ, 1.3 V dropout at 330 mA - higher current but larger 8-pin HVSSOP package. | Suitable for multi-rail systems needing >50 mA; not drop-in due to different pinout and footprint. | Select when higher output current or lower dropout under heavy load is required; verify PCB layout change. |
| NCP114AMX12T2G | 150 mA output, 2.5 µA IQ, ±2% accuracy, same SC-70-5 package - higher current rating but no AEC-Q100 Grade 1 certification. | Applicable in industrial or consumer designs; lacks automotive qualification and thermal hysteresis spec. | Choose for cost-sensitive non-automotive applications where AEC-Q100 is not mandated. |
Compared with TPS7B8233QDGNRQ1 and NCP114AMX12T2G, the NCV8715SQ12T2G uniquely balances ultra-low IQ (≤5.8 µA), AEC-Q100 Grade 1 compliance, and SC-70-5 footprint - making it optimal for space-constrained, battery-backed automotive modules where qualification and standby power dominate selection.

FAQ
What is the maximum input voltage rating for the NCV8715SQ12T2G?
The NCV8715SQ12T2G has an absolute maximum input voltage rating of 24 V, with recommended operating input voltage from 2.5 V to 24 V. Exceeding 24 V risks permanent damage. It is rated for automotive load-dump conditions up to 24 V, making it suitable for 12 V and 24 V vehicle platforms without external clamping.
Does the NCV8715SQ12T2G require a minimum ESR output capacitor?
No, the NCV8715SQ12T2G does not require a minimum ESR output capacitor. It is internally compensated for stability with standard X5R or X7R ceramic capacitors ranging from 0.47 µF to 10 µF. This eliminates the need for tantalum or aluminum electrolytic capacitors and simplifies design for automotive applications.
Is the NCV8715SQ12T2G qualified for automotive use?
Yes, the NCV8715SQ12T2G carries the NCV prefix and is AEC-Q100 qualified for Grade 1 (−40°C to +125°C ambient), PPAP-capable, and manufactured in onsemi's certified automotive facilities. It meets stringent reliability, traceability, and process control requirements for safety-critical vehicle subsystems.
What is the thermal shutdown behavior of the NCV8715SQ12T2G?
The NCV8715SQ12T2G activates thermal shutdown at 170°C junction temperature and includes 15°C hysteresis, meaning it resumes regulation only after cooling to ≤155°C. This prevents thermal oscillation during overload and protects against sustained overtemperature conditions in enclosed automotive enclosures.
Can the NCV8715SQ12T2G be used with a 0.47 µF output capacitor?
Yes, the NCV8715SQ12T2G is explicitly characterized and stable with a 0.47 µF ceramic output capacitor (X5R/X7R), as confirmed in the datasheet's Application Information section. This value provides adequate phase margin and transient response for most automotive low-power loads.
