onsemi NCV8715SQ15T2G

Overview

NCV8715SQ15T2G from onsemi is a 50 mA, fixed 1.5 V output, ultra-low quiescent current (max 5.8 µA) LDO linear voltage regulator with 2.5 V to 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 NCV8715SQ15T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.5 V fixed output, SC-70-5 package thermal performance (R_JA = 390°C/W), dropout voltage of 250–400 mV at 50 mA, PSRR of 56 dB at 100 kHz, and 75 µV_RMS output noise (200 Hz–100 kHz).

Technical Context

The NCV8715SQ15T2G integrates bandgap reference, MOSFET driver with current limiting, thermal shutdown circuitry, and UVLO protection in a single monolithic IC. Its architecture enables stable regulation across wide input voltage swings while maintaining ultra-low ground current independent of load.

It operates without minimum ESR output capacitors and is stable with ceramic capacitors ≥0.47 µF. The internal feedback loop ensures ±2% output accuracy across −40°C to +125°C ambient temperature, 0–50 mA load, and 3.0–24 V input.

Key Specifications

Pinout & Package

NCV8715SQ15T2G 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 0.65 mm pitch. Thermal resistance is 390°C/W (junction-to-air), and the exposed pad is not present - thermal dissipation relies on PCB copper area under pins.

FAQ

What is the maximum input voltage rating for the NCV8715SQ15T2G?

The NCV8715SQ15T2G has an absolute maximum input voltage rating of 24 V, with recommended operating range from 2.5 V to 24 V. It is rated for indefinite short-circuit output duration and includes internal current limiting and thermal shutdown to protect against overvoltage stress beyond specification limits. This makes NCV8715SQ15T2G suitable for direct connection to automotive battery rails subject to load-dump transients.

Does the NCV8715SQ15T2G require an external resistor network to set output voltage?

No, the NCV8715SQ15T2G is a fixed-output regulator with internally trimmed 1.5 V reference. It does not require external resistors or feedback components. The device achieves ±2% output accuracy across −40°C to +125°C ambient temperature, 0–50 mA load, and 3.0–24 V input without trimming - simplifying design and reducing BOM count. This fixed configuration is confirmed by its ordering code "SQ15" and marking "V5C".

What is the thermal resistance (R_JA) of the NCV8715SQ15T2G in its SC-70-5 package?

The NCV8715SQ15T2G in SC-70-5 (Case 419A) has a junction-to-air thermal resistance (R_JA) of 390°C/W, measured using standard JEDEC test board conditions (1 oz copper, 650 mm² heat-spreading area). This value assumes no exposed thermal pad - thermal performance depends heavily on PCB copper area connected to Pins 2 and 4 (N/C) and Pin 3 (GND). For higher power dissipation, layout optimization is essential.

Can the NCV8715SQ15T2G operate with a 0.47 µF output capacitor?

Yes, the NCV8715SQ15T2G is explicitly designed to be stable with ceramic output capacitors as low as 0.47 µF - no minimum ESR requirement. The datasheet confirms stability with X5R/X7R types in the 0.47–10 µF range. Using 0.47 µF minimizes footprint and cost while maintaining adequate phase margin and load transient response for 50 mA applications.

Is the NCV8715SQ15T2G pin-compatible with other variants in the NCV8715 family?

Yes, all SC-70-5 variants in the NCV8715 family - including NCV8715SQ12T2G, NCV8715SQ15T2G, NCV8715SQ18T2G, and others - share identical pinout, package dimensions, and thermal characteristics. Only the output voltage and top-side marking differ. This allows drop-in replacement across voltage options during design iteration or production change without PCB revision.
