Product details
Overview
NCV8715SQ21T2G from onsemi is a 50 mA ultra-low-quiescent-current LDO linear voltage regulator with fixed 2.1 V output, 2.5–24 V input range, ±2% output accuracy over load/line/temperature, 230–350 mV dropout at 50 mA, and AEC-Q100 Grade 1 qualification for automotive infotainment and safety systems.
For engineers reviewing the NCV8715SQ21T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.8 µA max ground current across full load and temperature, 60 dB PSRR at 100 kHz, 105 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 NCV8715SQ21T2G integrates a bandgap reference, MOSFET driver with current limiting, UVLO, and thermal shutdown circuitry in a single monolithic IC. Its low-dropout architecture maintains regulation down to 230 mV dropout at 50 mA load, enabling operation from batteries or wide-range supplies in harsh environments.
Designed for automotive-grade reliability, it features guaranteed performance from −40°C to +125°C ambient, MSL1 moisture sensitivity, 2 kV HBM ESD rating, and Pb-free/RoHS-compliant packaging - all validated per AEC-Q100 Rev G requirements for Grade 1 applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.1 V ±2% over full load, line, and temperature - ensures stable MCU core or sensor biasing without external feedback. |
| Input Voltage Range | 2.5 V to 24 V - supports direct connection to 12 V automotive battery rails including cold-crank (6.0 V min) and load-dump transients. |
| Quiescent Current | Max 5.8 µA over full load and temperature - enables always-on subsystems (e.g., CAN wake-up logic) with negligible battery drain. |
| Dropout Voltage | 230–350 mV at 50 mA - allows >90% efficiency at 2.1 V output from 3.1 V input, critical for low-voltage microcontroller domains. |
| PSRR | 60 dB at 100 kHz - suppresses high-frequency switching noise from DC-DC converters feeding adjacent analog circuits. |
| Output Noise | 105 µVRMS (200 Hz–100 kHz) - meets low-noise requirements for audio codecs and precision ADC references. |
| Thermal Shutdown | 170°C junction temperature with 15°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
NCV8715SQ21T2G is packaged in SC-70-5 (Case 419A), a 1.6 mm × 1.6 mm × 0.9 mm surface-mount package with 5 terminals. Thermal resistance RJA = 390°C/W enables operation up to 125°C ambient with minimal PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply | Accepts 2.5–24 V; requires ≥0.1 µF ceramic decoupling to ground for stability and transient immunity. |
| 2 (N/C) | No connection | Internally unconnected; may be tied to ground to improve thermal dissipation without electrical impact. |
| 3 (GND) | Power ground | Reference node for regulation and protection circuits; must be low-impedance path to system ground plane. |
| 4 (N/C) | No connection | Internally unconnected; optional ground tie improves thermal performance in thermally constrained layouts. |
| 5 (OUT) | Regulated output | Delivers 2.1 V ±2%; requires ≥0.47 µF ceramic capacitor to ground for loop stability and noise filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 5.8 µA max ensures <1 µA total system standby current when powering real-time clock or CAN transceiver logic. |
| AEC-Q100 Grade 1 | Qualified for −40°C to +125°C ambient operation - suitable for under-hood and dashboard-mounted automotive modules. |
| No minimum ESR requirement | Stable with 0.47–10 µF X5R/X7R ceramics - eliminates need for costly tantalum or polymer capacitors in cost-sensitive designs. |
| Integrated protection | Current limiting and thermal shutdown prevent latch-up or destruction during short-circuit or overheating events without external components. |
| High PSRR at 100 kHz | 60 dB rejection enables clean 2.1 V rail for noise-sensitive analog blocks adjacent to switching power supplies. |

|---|---|---|---|
| TPS7B6733QPWPRQ1 | 3.3 V fixed output, 250 mA rating, higher IQ (12 µA typ), same AEC-Q100 Grade 1 | Not suitable for 2.1 V logic; targets higher-current 3.3 V domains like CAN FD controllers | Select only if system requires 3.3 V and >50 mA load; not a drop-in replacement for NCV8715SQ21T2G. |
| NCP1117ST21T3G | 2.1 V fixed output, 1 A rating, higher IQ (6 mA typ), no AEC-Q100 qualification, TO-220/SOT-223 packages | Targeted at industrial/commercial use; lacks automotive temperature grade and low-IQ for battery-sensitive designs | Consider for non-automotive 2.1 V applications needing higher current; unsuitable for automotive Grade 1 deployment. |

FAQ
What is the maximum input voltage rating for the NCV8715SQ21T2G?
The NCV8715SQ21T2G has an absolute maximum input voltage rating of 24 V, with recommended operating range from 3.1 V to 24 V for 2.1 V output. Operation above 24 V risks permanent device damage per Absolute Maximum Ratings table.
Does the NCV8715SQ21T2G require an external resistor network to set output voltage?
No, the NCV8715SQ21T2G is a fixed-output regulator with factory-trimmed 2.1 V output. It does not support adjustable output via external resistors - the voltage is internally set and guaranteed within ±2% across load, line, and temperature.
What is the thermal shutdown threshold of the NCV8715SQ21T2G?
The NCV8715SQ21T2G activates thermal shutdown at 170°C junction temperature, with 15°C hysteresis to prevent oscillation. This threshold is guaranteed by design and characterization, not production-tested per unit.
Can the NCV8715SQ21T2G operate with a 0.47 µF output capacitor?
Yes, the NCV8715SQ21T2G is explicitly designed to be stable with 0.47 µF or greater ceramic output capacitors (X5R/X7R dielectrics). No minimum ESR is required, simplifying layout and reducing BOM cost.
Is the NCV8715SQ21T2G qualified for automotive applications?
Yes, the NCV8715SQ21T2G carries NCV prefix, is AEC-Q100 qualified (Grade 1: −40°C to +125°C ambient), PPAP capable, and manufactured in onsemi's automotive-certified facilities - meeting requirements for infotainment, ADAS, and safety systems.
