Overview
NCV8711BMTW330TBG from onsemi is an automotive-grade CMOS LDO regulator delivering 3.3 V at up to 100 mA output current, with 1.8 µA typical quiescent current, 215 mV typical dropout at 100 mA, and integrated power-good (PG) output for sequencing or microcontroller reset in always-on battery systems.
For engineers reviewing the NCV8711BMTW330TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, WDFNW6 (2×2 mm) package, ±1% output accuracy over −40°C to +125°C, PG threshold at 93% of nominal output, and compatibility with 1 µF ceramic output capacitors.
Technical Context
The NCV8711BMTW330TBG implements a precision bandgap reference (1.2 V), error amplifier, and internal PMOS pass transistor optimized for low dropout and ultra-low IQ. Its PG circuit uses a dedicated comparator with 93% VOUT threshold and 160 µs deglitch time to ensure reliable power monitoring.
It features built-in soft-start (600 µs typical startup for 3.3 V), thermal shutdown at 165°C with 20°C hysteresis, and over-current protection limiting peak output to 140 mA. The EN pin includes 300 nA internal pull-up and 0.9 V enable threshold, enabling direct connection to IN without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8711ASN330T1G | TSOP-5 package, same 3.3 V output and PG function, but higher RthJA = 178°C/W and no exposed pad. | Suitable for lower-power or less thermally constrained applications where PCB area is less critical than thermal performance. | Select NCV8711ASN330T1G only if WDFNW6 footprint is unavailable and thermal load remains below 40 mA at +85°C ambient. |
| TLE42754G | Pin-compatible 3.3 V LDO with 35 µA IQ, no PG output, and 400 mV dropout at 100 mA - lacks ultra-low IQ and PG functionality. | Used in non-always-on modules where standby current is less critical; requires external reset supervisor for sequencing. | Choose TLE42754G only when PG is unnecessary and higher IQ is acceptable; not suitable for long-term battery backup scenarios. |
Compared with NCV8711BMTW330TBG, the TSOP-5 variant trades thermal efficiency for legacy package compatibility, while TLE42754G sacrifices ultra-low IQ and integrated PG for broader industrial availability - neither offers drop-in replacement capability due to differing thermal and functional profiles.

FAQ
What is the maximum input voltage rating for NCV8711BMTW330TBG?
The NCV8711BMTW330TBG has an absolute maximum input voltage of 22 V, with recommended operating range from 2.7 V to 18 V. This allows safe operation during automotive load-dump events up to 22 V while maintaining regulation across cold-crank conditions down to 2.7 V. The device includes internal protection to prevent damage if the 22 V limit is briefly exceeded.
Does NCV8711BMTW330TBG require an external pull-up resistor on the PG pin?
Yes, NCV8711BMTW330TBG features an open-drain PG output that requires an external pull-up resistor - typically 100 kΩ to 3.3 V or 5 V - to generate a valid logic-high signal when output voltage is in regulation. The datasheet specifies PG leakage current ≤10 nA, ensuring minimal power draw from the pull-up network in always-on systems.
Can NCV8711BMTW330TBG operate without an enable signal connected?
Yes, NCV8711BMTW330TBG can operate without an external EN signal because it includes a 300 nA internal pull-up current source. When EN is left floating or tied directly to IN, the device remains enabled. This simplifies design in always-on applications and eliminates the need for external biasing components.
What is the thermal performance difference between NCV8711BMTW330TBG and the TSOP-5 version?
NCV8711BMTW330TBG in WDFNW6 achieves RthJA = 67°C/W, while the TSOP-5 variant (e.g., NCV8711ASN330T1G) has RthJA = 178°C/W. This 2.7× improvement allows NCV8711BMTW330TBG to deliver full 100 mA at +85°C ambient without derating, whereas the TSOP-5 version must reduce output current significantly above +50°C ambient to avoid thermal shutdown.
Is NCV8711BMTW330TBG compatible with 1 µF ceramic output capacitors?
Yes, NCV8711BMTW330TBG is explicitly characterized and guaranteed stable with ≥1 µF X7R ceramic output capacitors - no ESR requirements or additional series resistance needed. This eliminates reliance on larger, less reliable tantalum or aluminum electrolytic capacitors and supports miniaturized, high-reliability automotive PCB layouts.
