Product details
Overview
NCV8715SQ18T2G from onsemi is a 50 mA, fixed 1.8 V output low-dropout linear voltage regulator with ultra-low quiescent current (max 5.8 µA), wide 2.8–24 V input range, ±2% output accuracy over load/line/temperature, and AEC-Q100 Grade 1 qualification for automotive infotainment and safety systems.
For engineers reviewing the NCV8715SQ18T2G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 50 mA (230–350 mV), PSRR of 60 dB at 100 kHz, 95 µVRMS output noise (200 Hz–100 kHz), thermal shutdown at 170°C, and SC-70-5 package compatibility with space-constrained automotive PCBs.
Technical Context
The NCV8715SQ18T2G integrates a bandgap reference, MOSFET driver with current limiting, UVLO, and thermal shutdown circuitry in a single monolithic IC. Its internal architecture enables stable regulation down to 2.8 V input while maintaining ultra-low ground current across −40°C to +125°C ambient temperature.
It operates without minimum ESR output capacitors and is stable with ceramic capacitors ≥0.47 µF. The device's PSRR performance (60 dB @ 100 kHz) and low spectral noise density support sensitive analog and RF subsystems in automotive ECUs where supply rail cleanliness is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% over full load (0–50 mA), line (3.0–24 V), and temperature (−40°C to +125°C) |
| Input Voltage Range | 2.8 V to 24 V - supports direct battery connection in 12 V automotive systems with cold-crank margin |
| Quiescent Current | Max 5.8 µA at 50 mA load and full temperature range - enables always-on modules with <1 µA system standby leakage |
| Dropout Voltage | 230–350 mV at 50 mA - allows regulation from 2.03 V input, enabling operation during deep battery discharge |
| PSRR | 60 dB at 100 kHz - suppresses high-frequency switching noise from upstream DC-DC converters |
| Output Noise | 95 µVRMS (200 Hz–100 kHz) - meets low-noise requirements for ADC references and audio amplifiers |
| Thermal Shutdown | 170°C activation with 15°C hysteresis - protects against sustained overload or poor heatsinking in sealed enclosures |
Pinout & Package
NCV8715SQ18T2G is packaged in SC-70-5 (SC-88A), a 5-pin surface-mount package measuring 2.0 mm × 2.1 mm × 0.9 mm with gull-wing leads. Thermal resistance RJA = 390°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply | Accepts 2.8–24 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 or left floating |
| 3 (GND) | Power ground | Reference return path for regulation and protection circuits; must be low-impedance to minimize noise coupling |
| 4 (N/C) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation or left floating |
| 5 (OUT) | Regulated output | Delivers stable 1.8 V; requires ≥0.47 µF ceramic capacitor to GND for loop stability and load transient response |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +125°C ambient operation - suitable for engine bay and dashboard-mounted automotive modules |
| Ultra-low IQ | Max 5.8 µA across full load and temperature - extends battery life in telematics and remote keyless entry systems |
| No minimum ESR requirement | Stable with standard X5R/X7R ceramic capacitors ≥0.47 µF - eliminates need for costly tantalum or polymer alternatives |
| Integrated protection | Thermal shutdown + current limiting - prevents latch-up or destruction during short-circuit or overtemperature events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73318PDBVR | 300 mA output, 4 µA IQ, SOT-23-5 package, no AEC-Q100 qualification | Higher current capability but lacks automotive qualification and thermal shutdown hysteresis | Select when higher load current (>50 mA) is needed and AEC-Q100 is not required |
| NCP114AMX18T2G | 150 mA output, 2.5 µA IQ, same SC-70-5 package, AEC-Q100 Grade 1, but 2.5% accuracy | Lower accuracy (±2.5% vs ±2%) and reduced PSRR (55 dB @ 100 kHz) | Select when tighter quiescent current is prioritized over output precision and noise performance |
Compared with TLV73318PDBVR and NCP114AMX18T2G, the NCV8715SQ18T2G delivers superior accuracy (±2%), higher PSRR (60 dB), and guaranteed thermal hysteresis - making it the preferred choice for safety-critical automotive voltage rails where parameter consistency across temperature and lifetime is non-negotiable.

FAQ
What is the maximum input voltage rating for the NCV8715SQ18T2G?
The NCV8715SQ18T2G has an absolute maximum input voltage rating of 24 V, with recommended operating range from 2.8 V to 24 V. Operation above 24 V risks permanent damage, and the device incorporates internal protection to prevent latch-up under transient overvoltage conditions up to specified ESD ratings (2000 V HBM).
Does the NCV8715SQ18T2G require an external resistor network to set output voltage?
No, the NCV8715SQ18T2G is a fixed-output regulator with factory-trimmed 1.8 V nominal voltage. It does not support adjustable output via external resistors - the output is internally set and guaranteed within ±2% over full load, line, and temperature conditions without any external components.
Can the NCV8715SQ18T2G be used with ceramic output capacitors smaller than 1 µF?
Yes, the NCV8715SQ18T2G is explicitly designed for stability with ceramic output capacitors as low as 0.47 µF (X5R/X7R dielectric). Unlike many legacy LDOs, it imposes no minimum ESR requirement, allowing compact, low-cost, and highly reliable ceramic-only filtering without risk of oscillation.
What is the thermal shutdown behavior of the NCV8715SQ18T2G?
The NCV8715SQ18T2G activates thermal shutdown at 170°C junction temperature and includes 15°C hysteresis, meaning it resumes regulation only after junction temperature falls below 155°C. This prevents rapid cycling during sustained overload and ensures safe cooldown before restart in automotive under-hood environments.
Is the NCV8715SQ18T2G pin-compatible with other variants in the NCV8715 family?
Yes, all SC-70-5 packaged NCV8715 variants - including NCV8715SQ12T2G, NCV8715SQ15T2G, and NCV8715SQ18T2G - share identical pinout, footprint, and thermal pad configuration. This enables voltage-option flexibility on the same PCB layout without redesign or requalification.
