Product details
Overview
NCV8720BMT150TBG from onsemi is an automotive-grade 350 mA very low dropout (VLDO) linear regulator with NMOS pass transistor and separate bias rail (VBIAS), delivering 1.5 V ±2% output accuracy over −40 °C to +125 °C, ultra-low 110 mV typical dropout at full load, and 80 µA typical bias current - designed for FPGA, DSP, and camera power rails in space-constrained, noise-sensitive automotive systems.
For engineers reviewing the NCV8720BMT150TBG datasheet, pinout, applications, or equivalent options, key selection considerations include dual-rail operation (VIN/VBIAS), wettable-flank WDFN6 package compatibility, AEC-Q100 Grade 1 qualification, and fixed 1.5 V output with monotonic soft-start and thermal shutdown protection.
Technical Context
The NCV8720BMT150TBG implements a dual-input NMOS-based VLDO architecture: VIN supplies the pass element while VBIAS powers internal control circuitry, enabling stable regulation even when VIN approaches VOUT. Its built-in UVLO monitors VBIAS with 1.6 V turn-on threshold and 0.2 V hysteresis.
It features monotonic soft-start (140 µs to 95% VOUT), 420–1000 mA current limiting, and thermal shutdown activation at +160 °C with automatic recovery at +140 °C. PSRR exceeds 65 dB at 1 kHz for both VIN and VBIAS inputs, and output noise is 40 µVRMS (10 Hz–100 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over −40 °C to +125 °C - ensures stable core voltage for 1.5 V logic domains without external feedback. |
| Max Output Current | 350 mA continuous - supports mid-power digital loads like FPGA I/O banks or image sensor interfaces. |
| VIN Dropout Voltage | 110 mV typical at 350 mA - enables operation with minimal headroom, e.g., 1.61 V input for 1.5 V output. |
| VBIAS Range | 2.4 V to 5.5 V - decouples control circuitry supply from noisy main rail, improving PSRR and stability. |
| Bias Current | 80 µA typical - minimizes quiescent power draw in battery-backed or always-on subsystems. |
| PSRR @ 1 kHz | 65 dB (VBIAS), 65 dB (VIN) - suppresses switching noise from upstream DC/DC converters in post-regulation applications. |
| Thermal Shutdown | +160 °C activation / +140 °C reset - provides self-protecting operation under sustained overload or poor PCB thermal design. |
Pinout & Package
NCV8720BMT150TBG is housed in a 2 mm × 2 mm WDFN6 package (Case 511BR) with wettable flanks for automated optical inspection. The exposed thermal pad must be soldered to the PCB ground plane to achieve RJA = 65 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 1.5 V to load; requires ≥2.2 µF ceramic capacitor directly connected. |
| 2 - N/C | No connect | Not internally bonded; must remain unconnected per design - no routing or grounding. |
| 3 - EN | Enable control | Active-high logic input (1.1 V threshold); connects to VIN or VBIAS if unused to ensure default enable. |
| 4 - BIAS | Bias supply input | Powers internal reference and control circuits; must be ≥(VOUT + 1.4 V) = 2.9 V for full performance. |
| 5 - GND | Ground reference | Common return for IN, OUT, BIAS, and EN; ties to thermal pad for optimal thermal conduction. |
| 6 - IN | Main input supply | Feeds NMOS pass transistor; minimum input = VOUT + VDO_IN ≈ 1.61 V at full load. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail NMOS VLDO architecture | Enables independent optimization of power path (VIN) and control path (VBIAS), reducing sensitivity to input ripple and improving transient response. |
| Monotonic soft-start | Guarantees controlled 140 µs VOUT ramp to 95% of 1.5 V, eliminating inrush-induced system resets during power-up. |
| Ultra-low bias current | 80 µA typical (0.5 µA in shutdown) - extends battery life in always-on automotive modules such as CAN wake-up receivers. |
| Stable with 2.2 µF ceramic output cap | Eliminates need for large, costly tantalum or aluminum electrolytic capacitors - reduces board area and cost. |
| AEC-Q100 Grade 1 qualified | Validated for −40 °C to +125 °C ambient operation with PPAP capability - meets functional safety requirements for body electronics and ADAS sub-systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8170BMT150TBG | 300 mA max output, 120 mV dropout, same 1.5 V fixed output and WDFN6 package. | Limited current headroom for high-transient FPGA I/O; lower thermal margin at full load. | Select when 300 mA suffices and footprint compatibility is critical; verify thermal derating at 125 °C ambient. |
| TLD6512-15ES | 250 mA, integrated watchdog and diagnostic pins, wider VBIAS range (2.7–40 V), automotive ASIL-B ready. | Includes safety monitoring not present in NCV8720BMT150TBG; higher BOM cost and complexity. | Choose when functional safety diagnostics (e.g., for ASIL-B compliant clusters) are required alongside 1.5 V regulation. |
Compared with NCV8720BMT150TBG, NCV8170BMT150TBG offers identical pinout but reduced current capability, while TLD6512-15ES adds safety features at the expense of higher quiescent current and non-drop-in enable logic - making NCV8720BMT150TBG optimal for cost-sensitive, high-current, noise-critical automotive point-of-load use cases.

FAQ
What is the nominal output voltage of the NCV8720BMT150TBG?
The NCV8720BMT150TBG delivers a factory-programmed fixed output voltage of 1.5 V with ±2% accuracy across −40 °C to +125 °C ambient temperature. This value is encoded in the part number suffix "150" and confirmed in the ordering table on page 9 of the datasheet. The NCV8720BMT150TBG does not support adjustable output via external resistors - it is strictly a fixed-voltage device.
Does the NCV8720BMT150TBG require an external feedback network?
No, the NCV8720BMT150TBG does not require an external feedback network. It is a fixed-output LDO with internal voltage reference and trimming, configured at wafer sort for 1.5 V. The device uses only OUT, IN, GND, BIAS, and EN pins - no FB or ADJ connections are present or needed. This simplifies layout and eliminates resistor tolerance errors affecting regulation accuracy.
Can the NCV8720BMT150TBG operate with VBIAS lower than VIN?
Yes, the NCV8720BMT150TBG is explicitly designed for VBIAS to be independent of VIN and may be lower, equal to, or higher - as long as VBIAS remains within 2.4 V to 5.5 V and satisfies the minimum condition VBIAS ≥ (VOUT + 1.4 V) = 2.9 V. This decoupling allows cleaner biasing from a low-noise LDO while drawing main power from a higher-current, noisier source - a key advantage of its dual-rail architecture.
What is the thermal performance of the NCV8720BMT150TBG in its WDFN6 package?
The NCV8720BMT150TBG in the WDFN6 2 mm × 2 mm package achieves a junction-to-air thermal resistance (RJA) of 65 °C/W when mounted on a standard high-K 3″ × 3″ multilayer PCB with dedicated 125 mm² copper area and grounded thermal pad. At 350 mA and 1.5 V output, worst-case power dissipation is ~350 mW - resulting in ~23 °C rise above ambient, well within the +125 °C max junction limit under typical conditions.
Is the NCV8720BMT150TBG still in active production?
No - per the datasheet revision history (Rev. 4, February 2026), the NCV8720BMT150TBG is marked as discontinued. However, Aetrix Electronics maintains legacy inventory and supports ongoing production programs with traceable, verified stock and lifecycle coordination. Customers should consult Aetrix for current availability, last-time-buy options, and migration guidance to functionally aligned alternatives.
