Product details
Overview
NCV8716MT25TBG from onsemi is a 2.5 V fixed-output, 80 mA ultra-low-quiescent-current LDO linear voltage regulator designed for automotive and industrial power management. It operates across 2.5 V to 24 V input, delivers ±2% output accuracy over load/line/temperature, features 60 dB PSRR at 100 kHz, and draws only 3.4–5.8 µA ground current across full load and temperature (−40 °C to +125 °C). It is used in battery-powered telematics modules requiring stable low-noise 2.5 V rail under wide-input-voltage and low-power constraints.
For engineers reviewing the NCV8716MT25TBG datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional and application-level differences - all aligned to AEC-Q100 Grade 1 requirements and wDFN6 thermal performance data.
Technical Context
The NCV8716MT25TBG integrates a PMOS pass transistor with bandgap reference, thermal shutdown (155 °C trip, 25 °C hysteresis), and foldback current limiting. Its architecture enables stable regulation down to 400 mV dropout at 80 mA while maintaining ultra-low quiescent current - critical for always-on automotive subsystems.
It requires no minimum ESR output capacitor and is stable with 0.47 µF–10 µF X5R/X7R ceramics. Input and output decoupling are simplified: only a 0.1 µF ceramic on IN and ≥0.47 µF on OUT are mandatory, enabling compact PCB layouts in space-constrained ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% over −40 °C to +125 °C, full load (0–80 mA) and line (3.5–24 V) variation - ensures reliable logic-level supply for microcontrollers and sensors. |
| Input Voltage Range | 2.5 V to 24 V - supports direct connection to automotive battery (cold-crank down to 2.5 V) and industrial 24 V rails without pre-regulation. |
| Quiescent Current | 3.4 µA (typ) to 5.8 µA (max) at VIN = 24 V - enables >10-year battery life in always-on vehicle tracking units drawing <100 µA system standby current. |
| PSRR @ 100 kHz | 60 dB - suppresses high-frequency switching noise from DC-DC converters feeding the same board, preserving ADC reference stability. |
| Dropout Voltage | 400 mV (typ) to 640 mV (max) at 80 mA - allows operation with ≤300 mV headroom above 2.5 V output, e.g., from a 2.8 V LiFePO₄ cell. |
| Noise (200 Hz–100 kHz) | 160 µVRMS - low enough for powering precision analog front-ends (e.g., CAN transceiver bias rails) without added filtering. |
| Thermal Shutdown | 155 °C junction trip with 25 °C hysteresis - protects against sustained overload or poor heatsinking in sealed enclosures. |
Pinout & Package
NCV8716MT25TBG is housed in a thermally enhanced wDFN6 (2 mm × 2 mm, 0.65 mm pitch, Case 511BR) package with exposed thermal pad. The exposed pad (EXP) must be soldered to PCB ground plane for optimal thermal performance (RJA = 120 °C/W).
| 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 transient immunity and stability. |
| 2 - N/C | No connection | May be tied to GND to improve thermal dissipation; electrically isolated from internal circuitry. |
| 3 - GND | Power ground reference | Main ground return path; must be connected to EXP (exposed pad) and system ground plane. |
| 4 - N/C | No connection | May be tied to GND to improve thermal dissipation; electrically isolated from internal circuitry. |
| 5 - N/C | No connection | May be tied to GND to improve thermal dissipation; electrically isolated from internal circuitry. |
| 6 - OUT | Regulated 2.5 V output | Delivers up to 80 mA; 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 transmission control unit deployments. |
| Ultra-low IQ with full-load capability | 5.8 µA max IQ at 80 mA load and 24 V input - eliminates need for external enable sequencing in low-power wake-up circuits. |
| No minimum ESR requirement | Stable with 0.47–10 µF X5R/X7R ceramics - reduces BOM count and avoids tantalum capacitor reliability risks. |
| Integrated protection | Thermal shutdown + current limiting - prevents latch-up or damage during short-circuit or overtemperature events without external components. |
| Pb-free, Halogen-free, RoHS compliant | Meets automotive ELV and global environmental directives - supports end-of-life recycling and export compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73325PDBVR | 2.5 V, 300 mA, 65 µA IQ, SOT-23-5 package, no AEC-Q100 rating | Higher output current but 12× higher quiescent current; unsuitable for automotive always-on systems | Select only for non-automotive, higher-current, cost-sensitive industrial designs where thermal grade and ultra-low IQ are not required. |
| TPS78025DRVR | 2.5 V, 150 mA, 500 nA IQ, WSON-6 package, AEC-Q100 Grade 2 (−40 °C to +105 °C) | Lower IQ but limited to +105 °C ambient; lacks current limiting and has higher dropout (700 mV @ 150 mA) | Prefer for ultra-low-power battery IoT nodes; avoid in under-hood automotive locations exceeding +105 °C ambient. |
Compared with TLV73325PDBVR and TPS78025DRVR, the NCV8716MT25TBG uniquely balances AEC-Q100 Grade 1 qualification, 5.8 µA max IQ, integrated current limiting, and 24 V input tolerance - making it the only choice for automotive-grade 2.5 V LDOs requiring simultaneous wide VIN, ultra-low IQ, and full-temperature reliability.

FAQ
What is the maximum input voltage rating for the NCV8716MT25TBG?
The NCV8716MT25TBG has an absolute maximum input voltage rating of 24 V, with recommended operating range from 3.5 V to 24 V at 80 mA load. Operation above 24 V risks permanent damage per Absolute Maximum Ratings table; derating is advised for long-term reliability at elevated temperatures.
Does the NCV8716MT25TBG require an external resistor network to set output voltage?
No, the NCV8716MT25TBG is a fixed 2.5 V output device. It contains internal feedback resistors trimmed during wafer test; no external components are needed to configure the output voltage. This simplifies layout and improves accuracy versus adjustable LDOs subject to resistor tolerance drift.
Can the NCV8716MT25TBG be used without connecting the exposed thermal pad (EXP)?
No - the exposed pad (EXP) must be soldered to the PCB ground plane and electrically tied to Pin 3 (GND). Leaving EXP unconnected degrades thermal resistance from 120 °C/W to >200 °C/W, risking thermal shutdown under 80 mA load at ambient >85 °C. Thermal performance data assumes EXP-to-GND connection.
What is the minimum output capacitor value required for stability with the NCV8716MT25TBG?
The NCV8716MT25TBG requires a minimum 0.47 µF X5R or X7R ceramic capacitor from OUT to GND for guaranteed stability across temperature and load. Larger values (up to 10 µF) improve transient response but are not required for basic regulation. Tantalum or aluminum electrolytics are not recommended due to ESR sensitivity.
Is the NCV8716MT25TBG pin-compatible with other variants in the NCV8716 family?
Yes - all NCV8716 variants (e.g., NCV8716MT15TBG, NCV8716MT33TBG) share identical wDFN6 pinout and package dimensions. Only the output voltage and top-side marking differ; PCB layout and thermal design are fully reusable across the family, simplifying multi-voltage platform development.
