| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input power supply | Accepts 2.7–18 V; connects to bulk capacitor and upstream DC-DC or battery. |
| 2 - NC/ADJ | No-connect / Adjust | Not connected internally; may be tied to GND for thermal enhancement (not used in fixed-output version). |
| 3 - GND | Ground reference | Primary return path; must be connected to EPAD and system ground plane for thermal and noise integrity. |
| 4 - EN | Enable control | Active-high logic input; internal 300 nA pull-up allows direct connection to IN for always-on operation. |
| 5 - PG | Power-good indicator | Open-drain output pulled high externally; asserts high when VOUT ≥ 2.79 V for >320 µs after startup. |
| 6 - OUT | Regulated output | Delivers 3.0 V ±1% at up to 100 mA; requires ≥1 µF ceramic capacitor (X5R/X7R) for stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8711ASN300T1G | Same 3.0 V output and TSOP-5 package but lacks PG output; 1.3 µA IQ (vs. 1.8 µA); RthJA = 178 °C/W. | No power sequencing capability; suitable where reset coordination is handled externally or not required. | Select when PG is unnecessary and board space permits larger TSOP-5 footprint. |
| TLD1013EL | 3.3 V fixed output, 2.5 µA IQ, no PG, AEC-Q100 qualified; 300 mV dropout at 100 mA; requires ≥2.2 µF output cap. | Higher dropout and no PG limits use in cold-crank-sensitive or sequenced systems; optimized for LED bias rather than logic rails. | Consider only if 3.3 V is acceptable and PG functionality is omitted from system architecture. |
Compared with NCV8711BMTW300TBG, the NCV8711ASN300T1G offers lower IQ but sacrifices PG functionality and thermal performance, while TLD1013EL trades PG and dropout for higher output voltage and relaxed capacitor requirements - neither is pin-compatible, and both require layout changes.

FAQ
What is the output voltage tolerance of the NCV8711BMTW300TBG over temperature?
The NCV8711BMTW300TBG delivers 3.0 V output with ±1% accuracy from −40 °C to +85 °C, and ±2% from −40 °C to +125 °C. This specification is guaranteed by design and characterization per the datasheet's Electrical Characteristics table, ensuring predictable performance in under-hood automotive environments where the NCV8711BMTW300TBG is commonly deployed.
Does the NCV8711BMTW300TBG require an external pull-up resistor on the PG pin?
No, the NCV8711BMTW300TBG PG pin is open-drain and requires an external pull-up resistor (typically 10 kΩ to 100 kΩ) to a valid logic-high voltage (e.g., 3.3 V or 5 V) to generate a usable power-good signal. The datasheet Figure 3 shows a 100 kΩ pull-up; omitting it leaves PG floating and non-functional, so correct implementation is essential for sequencing or reset use cases involving the NCV8711BMTW300TBG.
Can the NCV8711BMTW300TBG operate during automotive cold-crank conditions?
Yes - the NCV8711BMTW300TBG supports input voltages as low as 2.7 V and has a 215 mV dropout at 100 mA, meaning it maintains 3.0 V regulation down to VIN = 3.215 V. This margin covers typical cold-crank minimums (~4.5 V for 12 V systems), and its 1.95 V UVLO threshold ensures reliable restart once voltage recovers - a key capability confirmed in the NCV8711BMTW300TBG's Electrical Characteristics and Typical Characteristics sections.
Is the NCV8711BMTW300TBG compatible with 1 µF ceramic output capacitors?
Yes, the NCV8711BMTW300TBG is explicitly characterized and guaranteed stable with ≥1 µF X5R/X7R ceramic output capacitors, as stated in the Features list and Typical Application Schematics. This eliminates reliance on larger, less reliable tantalum or aluminum electrolytic capacitors - a critical advantage for space-constrained automotive PCBs using the NCV8711BMTW300TBG.
How does the EN pin function on the NCV8711BMTW300TBG?
The EN pin on the NCV8711BMTW300TBG is active-high with an internal 300 nA pull-up, allowing direct connection to IN for always-on operation without external components. Its threshold is 0.9 V (typ.), with 0.1 V hysteresis, enabling clean enable/disable transitions even with noisy control signals - a behavior verified in the Electrical Characteristics table and Simplified Block Diagram of the NCV8711BMTW300TBG datasheet.
