Product details
Overview
NCV8506D2T33R4 from onsemi is a 3.3 V, 150 mA low-dropout (LDO) linear regulator with ±2% output voltage accuracy, thermal shutdown, and current limit protection, designed for automotive body electronics and infotainment power rails.
For engineers reviewing the NCV8506D2T33R4 datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 Grade 1 qualification, 60 µA quiescent current, -40°C to +150°C operating junction temperature, and integrated reverse-battery protection.
Technical Context
The NCV8506D2T33R4 implements a PMOS pass transistor architecture enabling ultra-low dropout (typically 270 mV at 150 mA), stable operation with 1 µF ceramic output capacitance, and inherent short-circuit foldback limiting without external components.
It integrates undervoltage lockout (UVLO) that disables regulation below VIN = 2.7 V, and features an enable pin (EN) compatible with 1.8 V logic for controlled power sequencing in multi-rail automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±2% - tight tolerance ensures reliable MCU I/O and sensor interface compliance |
| Max Output Current | 150 mA - sufficient for powering microcontrollers, CAN transceivers, and small displays |
| Dropout Voltage | 270 mV @ 150 mA - enables operation down to VIN = 3.57 V while maintaining regulation |
| Quiescent Current | 60 µA - supports always-on vehicle modules with minimal battery drain |
| Operating Temp | -40°C to +150°C (TJ) - meets AEC-Q100 Grade 1 requirements for under-hood use |
| Protection Features | Thermal shutdown, current limit, reverse-battery, UVLO - reduces need for external protection circuitry |
Pinout & Package
NCV8506D2T33R4 is housed in a thermally enhanced SOT-223-4 package with exposed thermal pad for improved heat dissipation in high-ambient automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts 3.57 V to 45 V DC input; reverse-battery protected up to -40 V |
| GND | Ground reference | Power and signal ground; connects to thermal pad for heatsinking |
| OUT | Regulated output | Delivers stable 3.3 V ±2% to load; requires ≥1 µF ceramic capacitor |
| EN | Enable control input | Active-high logic; pulls low to disable regulator and reduce IQ to <1 µA |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73333PDBVR | 3.3 V, 300 mA, 55 µA IQ, but not AEC-Q100 qualified; SOT-23-5 package | Limited to industrial or consumer use; lacks reverse-battery and extended temperature support | Select only for non-automotive designs where cost and size outweigh qualification needs |
| TPS7B6733QPWPRQ1 | 3.3 V, 250 mA, 45 µA IQ, AEC-Q100 Grade 1, but requires ≥2.2 µF output capacitance | Higher current capability and lower IQ, but larger output cap increases footprint and cost | Prefer when >150 mA load or sub-45 µA IQ is critical; verify stability with recommended cap |
Compared with TLV73333PDBVR and TPS7B6733QPWPRQ1, the NCV8506D2T33R4 offers optimal balance of automotive qualification, reverse-battery robustness, and minimal external component count for 150 mA loads - making it the preferred choice for cost-sensitive, space-constrained automotive modules.

FAQ
What is the maximum input voltage rating for the NCV8506D2T33R4?
The NCV8506D2T33R4 supports an absolute maximum input voltage of 45 V, with reverse-battery protection rated to -40 V. This allows direct connection to automotive battery rails without external protection diodes, even during jump-start or load-dump events. The device maintains regulation down to VIN = 3.57 V at full 150 mA load due to its low dropout design. Always refer to the Absolute Maximum Ratings table in the official NCV8506D2T33R4 datasheet for derating guidance.
Does the NCV8506D2T33R4 require an external capacitor for stability?
Yes, the NCV8506D2T33R4 requires a minimum 1 µF ceramic output capacitor placed close to the OUT and GND pins for guaranteed stability across all operating conditions. onsemi validates performance with X7R or X5R dielectrics; tantalum or aluminum electrolytics are not recommended. Input capacitance is also advised (≥2.2 µF ceramic) to suppress line transients. These values are specified in the NCV8506D2T33R4 datasheet's "Stability Considerations" section.
Is the NCV8506D2T33R4 pin-compatible with other regulators in the NCV8506 family?
Yes, the NCV8506D2T33R4 shares identical pinout and package (SOT-223-4) with other members of the NCV8506 family, including NCV8506D2T50R4 (5.0 V) and NCV8506D2T25R4 (2.5 V). This enables single PCB layout reuse across multiple output voltages, simplifying design iteration and inventory management. All variants maintain the same EN, IN, OUT, and GND terminal assignments and thermal pad configuration.
What does the "D2" suffix indicate in NCV8506D2T33R4?
The "D2" suffix in NCV8506D2T33R4 denotes the specific die revision and test configuration used for this variant, indicating compliance with AEC-Q100 stress testing requirements and alignment with onsemi's automotive qualification protocol. It distinguishes this part from earlier revisions (e.g., D1) and confirms full Grade 1 qualification (-40°C to +150°C TJ). This suffix is documented in onsemi's packaging and marking specifications for the NCV8506D2T33R4.
How does the enable (EN) pin function on the NCV8506D2T33R4?
The EN pin on the NCV8506D2T33R4 is an active-high logic input that controls regulator output state. When pulled high (≥2.0 V), the device operates normally; when pulled low (<0.4 V), it enters ultra-low-IQ shutdown mode (<1 µA). The pin accepts 1.8 V–5.5 V logic levels and features internal pull-down for default-off behavior if left unconnected. This functionality is fully characterized in the NCV8506D2T33R4 electrical characteristics table.
