Product details
Overview
NCV8711BMTW500TBG from onsemi is an automotive-grade CMOS LDO regulator delivering 5.0 V fixed output at up to 100 mA, with 1.8 µA typical quiescent current, 215 mV dropout at 100 mA, ±1% output accuracy, and integrated power-good (PG) output for sequencing or microcontroller reset in battery-powered always-on systems.
For engineers reviewing the NCV8711BMTW500TBG datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (WDFNW6-6), PG functionality confirmation, thermal performance data (RthJA = 67°C/W), stability with 1 µF ceramic capacitors, and AEC-Q100 qualified operation across −40°C to +125°C.
Technical Context
The NCV8711BMTW500TBG implements a precision bandgap reference (1.2 V) and error amplifier driving a PMOS pass transistor, enabling low-dropout regulation and fast transient response. Its internal UVLO (1.95 V threshold) and soft-start circuit suppress inrush current during power-up.
Version B integrates a dedicated PG comparator with 93% VOUT threshold, 160 µs deglitch time, and 320 µs delay, referenced to the regulated output and independent of input voltage variations. Thermal shutdown activates at 165°C with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±1% over −40°C to +125°C - ensures stable MCU core or sensor rail without external resistors. |
| Quiescent Current | 1.8 µA typ. at 100 mA load - enables >10-year battery life in automotive body control modules with continuous monitoring. |
| Dropout Voltage | 215 mV typ. at 100 mA - supports regulation down to VIN = 5.215 V, critical for cold-crank scenarios in 12 V systems. |
| Power Good Output | Dedicated open-drain PG pin with 93% VOUT threshold and 320 µs delay - provides reliable system reset timing for microcontrollers. |
| Input Voltage Range | 2.7 V to 18 V - accommodates wide automotive supply transients including load dump (up to 18 V) and start-stop operation. |
| Thermal Resistance | RthJA = 67°C/W (WDFNW6) - allows 100 mA continuous output at +85°C ambient without heatsink in standard PCB layout. |
| Stability | Stable with 1 µF ceramic output capacitor - eliminates need for large tantalum or electrolytic capacitors, reducing board space and cost. |
Pinout & Package
NCV8711BMTW500TBG is packaged in a Pb-free WDFNW6 (2 mm × 2 mm, 0.65 mm pitch) with exposed thermal pad (EPAD) that must be soldered to GND for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input power supply | Accepts 2.7–18 V; connects to bulk capacitance before LDO input filter. |
| 2 - NC/ADJ | No-connect / adjust reference | Internally tied to feedback node; must remain unconnected for fixed 5.0 V operation. |
| 3 - GND | Ground reference | Primary return path for load current and internal bias; connects directly to EPAD. |
| 4 - EN | Enable control input | Active-high logic; internal 300 nA pull-up allows default-enable if left floating. |
| 5 - PG | Power-good status output | Open-drain signal pulled high externally; asserts high when VOUT ≥ 4.65 V (93% of 5.0 V). |
| 6 - OUT | Regulated output | Delivers 5.0 V ±1% at up to 100 mA; requires 1 µF ceramic capacitor to GND for stability. |
| EP - EPAD | Thermal and electrical ground | Mandatory GND connection for thermal dissipation; contributes to RthJCb = 11°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 1.8 µA typical quiescent current enables >10-year standby in always-on automotive modules. |

IC Role / Device Role / Timing Role: Low-noise LDO with 240 µVRMS output noise; PG output holds SoC in reset until rail settles within tolerance. Use Value: 1 µF ceramic stability reduces BOM count vs. legacy tantalum solutions; AEC-Q100 Grade 1 ensures operation across full vehicle lifecycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8711ASN500T1G | Same 5.0 V output and electrical specs, but TSOP-5 package (RthJA = 178°C/W) and no PG output. | Lacks power-good signaling; unsuitable for systems requiring sequenced power-up or reset generation. | Select only if PG is unnecessary and thermal budget allows higher junction temperature rise. |
| TLE42754G | 5.0 V fixed LDO with 35 µA IQ, 400 mV dropout at 100 mA, and integrated watchdog timer - no PG output. | Higher IQ and dropout reduce battery life and cold-crank margin; watchdog adds complexity not present in NCV8711BMTW500TBG. | Choose only if watchdog functionality is required and thermal derating is acceptable. |
Compared with NCV8711ASN500T1G, the NCV8711BMTW500TBG adds PG functionality and superior thermal performance via WDFNW6 packaging; compared with TLE42754G, it delivers 20× lower IQ and 40% lower dropout - critical for extended battery runtime and robust cold-crank operation.

FAQ
What is the maximum input voltage rating for NCV8711BMTW500TBG?
The NCV8711BMTW500TBG supports a maximum input voltage of 18 V continuously, with absolute maximum rating up to 22 V for transient conditions such as automotive load dump. This rating is validated per the device's Maximum Ratings table and applies across the full operating temperature range of −40°C to +125°C.
Does NCV8711BMTW500TBG require an external resistor divider for 5.0 V output?
No, the NCV8711BMTW500TBG is a fixed-output variant - its 5.0 V regulation is achieved internally using factory-trimmed feedback resistors. Pin 2 (NC/ADJ) is not connected internally for this version and must remain unconnected in the circuit.
How does the power-good (PG) output behave during startup and fault conditions?
The NCV8711BMTW500TBG PG pin asserts high (open-drain, requires external pull-up) when VOUT reaches ≥93% of 5.0 V (≥4.65 V), with a 320 µs delay after regulation is achieved. It pulls low if VOUT drops below 90% (4.5 V) and includes 160 µs deglitching to reject noise-induced false trips.
Can NCV8711BMTW500TBG operate with ceramic output capacitors smaller than 1 µF?
No - the NCV8711BMTW500TBG is characterized and guaranteed stable only with ≥1 µF effective ceramic output capacitance (including DC bias and temperature effects). Using smaller values may cause oscillation or degraded transient response, as confirmed in the Electrical Characteristics and Application Information sections.
Is NCV8711BMTW500TBG pin-compatible with other versions in the NCV8711 family?
No - the NCV8711BMTW500TBG uses the WDFNW6-6 package, while TSOP-5 variants (e.g., NCV8711ASN500T1G) have different pinouts and thermal characteristics. The WDFNW6 pin 2 is NC/ADJ and pin 5 is PG, whereas TSOP-5 pin 4 serves dual ADJ/PG function depending on version - direct PCB replacement is not possible.
