Product details
Overview
NCV8715SQ25T2G from onsemi is a 50 mA, fixed 2.5 V output, automotive-grade LDO linear voltage regulator in SC-70-5 (SC-88A) package. It operates from 3.5 V to 24 V input, delivers ±2% output accuracy over load/line/temperature, features ultra-low 5.8 µA max quiescent current, and integrates thermal shutdown and current limiting - designed for always-on power domains in infotainment and safety systems.
For engineers reviewing the NCV8715SQ25T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 Grade 1 qualification (−40°C to +125°C), 260 mV typical dropout at 50 mA, 60 dB PSRR at 100 kHz, and 115 µVRMS output noise (200 Hz–100 kHz), critical for low-noise analog and microcontroller supply rails.
Technical Context
The NCV8715SQ25T2G uses a bandgap reference and MOSFET pass element to achieve stable 2.5 V regulation across wide input (3.5–24 V) and load (0–50 mA) ranges. Its internal architecture includes UVLO, thermal shutdown with 170°C trip and 15°C hysteresis, and foldback current limiting - all implemented without external components.
It is optimized for low-noise operation: the error amplifier and feedback network are designed to minimize output spectral noise density, and the regulator remains stable with ceramic output capacitors as low as 0.47 µF - eliminating ESR requirements and simplifying layout in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% over −40°C to +125°C, 0–50 mA load, and 3.5–24 V input - ensures reliable MCU core or sensor biasing without trimming. |
| Max Output Current | 50 mA continuous - sufficient for powering low-power MCUs, CAN transceivers, or precision ADCs in distributed ECUs. |
| Quiescent Current | Max 5.8 µA over full temperature and load range - enables >10-year battery life in vehicle keep-alive circuits. |
| Dropout Voltage | 260–450 mV at 50 mA - allows operation down to VIN = 2.75 V while maintaining regulation, supporting cold-crank scenarios. |
| PSRR | 60 dB at 100 kHz - suppresses high-frequency switching noise from DC-DC converters feeding the LDO input. |
| Output Noise | 115 µVRMS (200 Hz–100 kHz) - meets stringent noise budgets for audio codecs and analog front-ends. |
| Thermal Shutdown | 170°C junction trip with 15°C hysteresis - protects against sustained overload or poor PCB heatsinking in sealed enclosures. |
Pinout & Package
NCV8715SQ25T2G is housed in SC-70-5 (SC-88A) package, 2.0 mm × 2.1 mm × 0.9 mm, with wettable flanks for automated optical inspection. Thermal resistance RJA = 390°C/W (standard board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 3.5–24 V; requires ≥0.1 µF ceramic decoupling to GND for stability and transient response. |
| 2 (N/C) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation or left floating. |
| 3 (GND) | Power ground reference | Low-impedance return path; must be connected directly to system ground plane with minimal trace length. |
| 4 (N/C) | No connection | Internally unconnected; same thermal handling options as Pin 2. |
| 5 (OUT) | Regulated 2.5 V output | Delivers up to 50 mA; requires ≥0.47 µF ceramic capacitor to GND for loop stability and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation - suitable for engine bay, ADAS camera, and body control modules. |
| Ultra-low IQ | 4.7 µA typical, 5.8 µA max across full range - reduces parasitic drain in always-on domains such as telematics wake-up circuitry. |
| No minimum ESR requirement | Stable with 0.47–10 µF X5R/X7R ceramics - eliminates need for tantalum or aluminum electrolytic, lowering BOM cost and size. |
| High PSRR at 100 kHz | 60 dB attenuation of ripple from upstream DC-DC converters - preserves signal integrity in mixed-signal SoC power domains. |
| Integrated protection | Thermal shutdown + current limiting - prevents latch-up or damage during short-circuit or overtemperature events without external circuitry. |

FAQ
What is the maximum input voltage rating for the NCV8715SQ25T2G?
The NCV8715SQ25T2G has an absolute maximum input voltage rating of 24 V, with recommended operating input voltage ranging from 3.5 V to 24 V. Operation above 24 V risks permanent damage, and operation below 3.5 V may cause dropout or loss of regulation at full 50 mA load. The device is designed for automotive battery-supplied systems including cold-crank and load-dump conditions.
Does the NCV8715SQ25T2G require an external capacitor on the output pin?
Yes, the NCV8715SQ25T2G requires a minimum 0.47 µF ceramic capacitor (X5R or X7R dielectric) between the OUT and GND pins for stability. Larger values up to 10 µF are supported and improve line/load transient response. Unlike older LDOs, it imposes no minimum ESR requirement - enabling use of low-cost, small-footprint MLCCs without risk of oscillation.
Is the NCV8715SQ25T2G qualified for automotive applications?
Yes, the NCV8715SQ25T2G carries the NCV prefix indicating automotive qualification. It is AEC-Q100 Grade 1 certified (−40°C to +125°C ambient), PPAP-capable, and manufactured in onsemi's IATF 16949-certified facilities. Its design includes thermal shutdown with hysteresis and current limiting - meeting functional safety requirements for ASIL-B supporting subsystems.
What is the typical dropout voltage of the NCV8715SQ25T2G at 50 mA load?
The typical dropout voltage of the NCV8715SQ25T2G at 50 mA load is 260 mV, with a maximum specified value of 450 mV under worst-case conditions (−40°C to +125°C). This means the device maintains 2.5 V regulation as long as input voltage stays ≥2.76 V - making it suitable for operation during automotive cold-crank events where battery voltage dips to ~6.5 V.
How does the NCV8715SQ25T2G handle thermal overload?
The NCV8715SQ25T2G incorporates a thermal shutdown circuit that disables the pass element when junction temperature reaches 170°C, with 15°C hysteresis. Once tripped, the device remains off until temperature falls to ~155°C, then automatically recovers. This behavior is guaranteed by design and characterization - no external thermal monitoring is required for basic protection in standard PCB layouts.
