Product details
Overview
NCV59152DSADJR4G from onsemi is an automotive-grade adjustable-output, very low-dropout (VLDO) linear regulator delivering up to 1.5 A output current with 300 mV typical dropout at full load, stable with ceramic output capacitors, and featuring logic-compatible enable and adjustable feedback (ADJ) pins - used for post-regulation in FPGA/DSP power supplies and battery-charger systems.
For engineers reviewing the NCV59152DSADJR4G datasheet, pinout, applications, or equivalent options, key selection considerations include its AEC-Q100 qualification, D2PAK-5 thermal performance (RJA = 52°C/W), adjustable output via external resistor divider, reverse output current protection, and error flag functionality for fault monitoring in safety-critical embedded power rails.
Technical Context
The NCV59152DSADJR4G implements a high-precision bandgap reference (1.24 V nominal at ADJ pin) with low-bias-current feedback sensing (≤350 nA), enabling accurate adjustable output voltage configuration. Its internal architecture integrates fast-transient-response compensation optimized for ceramic capacitor stability and includes dedicated CMOS/TTL-compatible EN and open-collector FLG pins.
It operates across −40°C to +125°C junction temperature, supports input voltages from 2.24 V to 13.5 V, and incorporates thermal shutdown, current limiting (2.0–3.0 A), and reverse output current protection - all critical for automotive point-of-load regulation where supply transients and backup-battery scenarios occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.5 A maximum - sufficient to power mid-tier FPGAs, DSPs, or microcontrollers without external pass devices. |
| Dropout Voltage | 300 mV typical at 1.5 A - enables operation with minimal VIN–VOUT margin, e.g., 3.3 V output from 3.6 V battery input. |
| Reference Voltage | 1.24 V (D2PAK package) - sets output via R1/R2 divider; accuracy ±1.5% over temperature ensures tight regulation. |
| Ground Current | 40–80 mA at 1.5 A load - low quiescent current preserves efficiency in always-on automotive subsystems. |
| Enable Threshold | 1.8 V (enable), 0.8 V (shutdown) - compatible with 1.8 V/3.3 V logic without level-shifting. |
| Error Flag Threshold | 95% of VOUT nominal with 2% hysteresis - provides robust undervoltage detection for system-level fault recovery. |
| Input Voltage Range | 2.24 V to 13.5 V - supports wide-input automotive and industrial DC rails including 12 V battery systems. |
Pinout & Package
D2PAK−5 package (Case 936A), thermally enhanced with exposed tab connected to GND; suitable for high-power dissipation in compact PCB layouts with copper heat spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable Input | CMOS/TTL-compatible control: logic high ≥1.8 V enables regulator; low ≤0.8 V places device in ultra-low-IQ shutdown (≤5 µA). |
| 2 (VIN) | Input Supply | Primary power input (2.24–13.5 V); supplies both internal circuitry and output load current. |
| 3 (GND) | Ground Reference | Common return path for input, output, and internal circuits; tab is electrically tied to this pin. |
| 4 (VOUT) | Regulated Output | Delivers adjustable output voltage set by external R1/R2 divider; capable of 1.5 A continuous current. |
| 5 (ADJ) | Feedback Input | Senses voltage at divider midpoint; maintains 1.24 V reference - determines VOUT = 1.24 × (1 + R1/R2). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Rated for automotive applications (Grade 1: −40°C to +125°C), with PPAP capability and unique site/control change tracking via NCV prefix. |
| Ceramic-Capacitor Stable | Guaranteed stability with ≥47 µF X5R/X7R ceramic output capacitor - eliminates need for electrolytic or tantalum, reducing footprint and improving reliability. |
| Reverse Output Current Protection | Prevents reverse current flow when VOUT > VIN (e.g., backup battery scenario), protecting upstream sources without external diodes. |
| Fast Transient Response | Minimizes output voltage deviation during rapid load steps (e.g., FPGA core switching), supported by internal compensation and low ESR cap compatibility. |
| Integrated Fault Monitoring | Open-collector FLG pin asserts low when VOUT drops below 95% nominal - enables system MCU to log faults or initiate safe shutdown. |
Applications
| Automotive Body Control Module (BCM) | FPGA Core Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV59152MNADJTYG | Same electrical specs but in DFN8 (4×4 mm) package; lower RJA (75°C/W vs. 52°C/W) due to smaller thermal mass and different PCB layout requirements. | Better suited for space-constrained designs with adequate copper area; less suitable for high-ambient-temperature environments without thermal vias. | Select NCV59152MNADJTYG when board area is limited and thermal management via PCB vias is feasible. |
| NCV8664DSADJR4G | Lower output current (500 mA), higher dropout (600 mV typ. @ 500 mA), no error flag; shares AEC-Q100 qualification and D2PAK-5 package. | Targeted at low-power automotive sensors or CAN transceivers - insufficient for FPGA or processor core rails. | Choose NCV8664DSADJR4G only for cost-sensitive, low-current automotive sub-systems where fault monitoring is not required. |
Compared with NCV59152MNADJTYG and NCV8664DSADJR4G, the NCV59152DSADJR4G uniquely balances 1.5 A capability, D2PAK-5 thermal robustness, and integrated fault signaling - making it optimal for automotive and industrial loads demanding both power and diagnostics.

FAQ
What is the minimum input voltage required for NCV59152DSADJR4G to regulate a 1.2 V output?
The NCV59152DSADJR4G requires a minimum input voltage of 2.24 V per its Recommended Operating Conditions. For a 1.2 V output, this implies a minimum headroom of ~1.04 V - well above the 300 mV typical dropout, ensuring stable regulation even at elevated temperatures and full load. The device will not operate below 2.24 V input regardless of output setting.
Does NCV59152DSADJR4G require an external output capacitor, and what type is recommended?
Yes, the NCV59152DSADJR4G requires an external output capacitor for stability and transient performance. The datasheet specifies ≥47 µF ceramic (X5R or X7R) as mandatory - electrolytic or tantalum capacitors are not recommended. This ceramic requirement reduces size, improves reliability, and enables fast transient response without phase-margin compromises.
How does the error flag (FLG) pin function on NCV59152DSADJR4G?
The NCV59152DSADJR4G does not include an FLG pin - it is a 5-pin D2PAK device with EN, VIN, GND, VOUT, and ADJ pins only. The FLG pin appears only on 8-pin variants (e.g., DFN8 versions). Confusion may arise from family-level documentation; the NCV59152DSADJR4G relies on external monitoring or system-level supervision for fault detection.
Can NCV59152DSADJR4G be used in non-automotive applications despite its NCV prefix?
Yes, the NCV59152DSADJR4G is fully functional in industrial, medical, and test equipment applications. Its NCV prefix denotes AEC-Q100 qualification and enhanced process controls - benefits that improve reliability and longevity in any demanding environment, not just automotive. No derating or special handling is needed outside automotive use cases.
What is the thermal resistance (RJA) of NCV59152DSADJR4G in standard PCB layout?
The NCV59152DSADJR4G in D2PAK-5 package has a junction-to-ambient thermal resistance (RJA) of 52°C/W when mounted on a PCB with 100 mm² of 2.0 oz copper heat-spreading area. This value assumes standard layout practices - adding thermal vias under the exposed tab can further reduce RJA, but the rated 52°C/W serves as the baseline for worst-case thermal design.
