Product details
Overview
NCV59152MNADJTYG 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 open-collector error flag pins - used for post-regulation in FPGA/DSP power supplies and automotive infotainment domain controllers.
For engineers reviewing the NCV59152MNADJTYG datasheet, pinout, applications, or equivalent options, key selection considerations include its AEC-Q100 qualification, adjustable output via external resistor divider (1.24 V reference), thermal shutdown, reverse output current protection, and DFN8-4×4 Pb-free package with exposed thermal pad.
Technical Context
The NCV59152MNADJTYG implements a precision bandgap-referenced error amplifier controlling a PMOS pass transistor, enabling fast transient response and low ground current. Its ADJ pin maintains a precise 1.24 V reference to ground, allowing programmable output voltages ≥1.24 V using two external resistors.
It operates across −40°C to +125°C junction temperature, supports input voltages from 2.24 V to 13.5 V, and integrates CMOS/TTL-compatible EN control, open-collector FLG for undervoltage detection (95% VOUT threshold with 2% hysteresis), and internal current limiting (2.0–3.0 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.5 A maximum - sufficient to power high-current FPGA I/O banks or DSP core rails without external boost. |
| Dropout Voltage | 300 mV typical at 1.5 A - enables regulation from low headroom sources like 3.3 V or 2.8 V supplies down to 1.24 V outputs. |
| Reference Voltage | 1.240 V (DFN8 package) - sets minimum output voltage and defines accuracy of externally adjusted VOUT. |
| Ground Current | 40–80 mA at 1.5 A load - directly impacts system efficiency and thermal design in high-current applications. |
| Enable Threshold | 1.8 V min for enable, 0.8 V max for shutdown - ensures compatibility with 1.8 V/3.3 V logic without level-shifting. |
| Error Flag Threshold | 95% nominal VOUT with 2% hysteresis - provides reliable undervoltage detection for safety-critical automotive subsystems. |
| Input Voltage Range | 2.24 V to 13.5 V - supports direct connection to automotive battery (with transient clamping) or intermediate DC-DC outputs. |
| Junction Temp Range | −40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and cockpit electronics. |
Pinout & Package
NCV59152MNADJTYG is housed in a thermally enhanced DFN8-4×4 mm package (Case 488AF) with an exposed copper thermal pad (EP) connected to GND. The 8-pin layout supports compact PCB placement and efficient heat dissipation via soldered thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection - must be decoupled within 1 inch with ≥1 µF ceramic capacitor for stability. |
| 2 | EN | CMOS/TTL-compatible enable input - logic high (>1.8 V) activates regulator; low (<0.8 V) places device in ultra-low-IQ shutdown (≤5 µA). |
| 3 | GND | Analog and power ground reference - tied internally to exposed pad; requires solid thermal/via connection to PCB ground plane. |
| 4 | VOUT | Regulated output node - connects to load and output capacitor (≥47 µF ceramic); feeds feedback network for adjustable versions. |
| 5 | ADJ | Feedback input for adjustable configuration - held at 1.24 V; forms resistor divider with R1/R2 to set VOUT = 1.24 × (1 + R1/R2). |
| 6 | FLG | Open-collector error flag - sinks up to 5 mA when VOUT drops below 95% nominal; requires external pull-up to monitored rail. |
| 7, 8 | NC | No internal connection - left unconnected; no routing or stitching required. |
| EP | Exposed Pad | Thermal and electrical ground - must be soldered to ≥500 mm² 2 oz copper area for RJA = 75°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 1 (−40°C to +125°C) with PPAP capability - validated for automotive power management in ADAS and body control modules. |
| Ceramic-Capacitor Stable | Guaranteed stability with ≥47 µF X5R/X7R ceramic output capacitor - eliminates need for bulk electrolytic, reducing board space and aging risk. |
| Fast Transient Response | Sub-500 µs startup time and low output impedance - maintains tight regulation during FPGA core state transitions or burst-mode loads. |
| Reverse Output Current Protection | Withstands VOUT–VIN ≤ 6.5 V during shutdown - prevents backup battery discharge through regulator in dual-supply systems. |
| Integrated Protection | Thermal shutdown, current limiting (2–3 A), and reverse current blocking - eliminates need for external fault-handling circuitry. |
| Low Ground Current | 40–80 mA at 1.5 A load - improves overall system efficiency vs. legacy LDOs with >100 mA quiescent draw. |
Applications

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 |
|---|---|---|---|
| TPS7A8300RGRT | Lower IQ (12 µA vs. 40 mA), higher cost, 2-A rating, fixed/adj variants - uses different feedback topology (VREF = 0.8 V). | Preferred for ultra-low-power battery systems; less suitable for high-current automotive due to thermal limits in 3×3 QFN. | Select TPS7A8300RGRT only if sub-100 µA quiescent current is mandatory and load ≤1.2 A. |
| MAX8526ETA+ | Higher dropout (450 mV @1.5 A), no AEC-Q100, 1.22 V reference, smaller 2×2 TDFN - lacks FLG and reverse current protection. | Suitable for industrial non-automotive designs where qualification and fault signaling are not required. | Choose MAX8526ETA+ only for cost-sensitive, non-automotive applications with relaxed thermal and safety requirements. |
Compared with TPS7A8300RGRT and MAX8526ETA+, the NCV59152MNADJTYG delivers superior thermal robustness in automotive environments, integrated fault signaling via FLG, and guaranteed reverse current blocking - making it the optimal choice for AEC-Q100-compliant systems demanding reliability over minimal IQ.

FAQ
What is the minimum input voltage required for NCV59152MNADJTYG to regulate a 1.24 V output?
The NCV59152MNADJTYG requires a minimum input voltage of 2.24 V per its Recommended Operating Conditions. This ensures proper operation even at the lowest specified output (1.24 V) with margin for dropout and internal circuitry - the 300 mV typical dropout does not apply below 1.74 V nominal output due to internal architecture constraints.
Does NCV59152MNADJTYG require an external resistor divider for output voltage setting?
Yes, the NCV59152MNADJTYG is an adjustable-output regulator and requires an external resistor divider connected between VOUT, ADJ, and GND. The ADJ pin maintains a precise 1.24 V reference, so VOUT = 1.24 V × (1 + R1/R2), where R2 connects from ADJ to GND and R1 from VOUT to ADJ.
How is thermal performance affected by the exposed pad on NCV59152MNADJTYG?
The exposed pad (EP) of the NCV59152MNADJTYG must be soldered to a ≥500 mm² 2 oz copper area to achieve the specified RJA = 75°C/W. Without proper thermal pad connection, junction temperature rise increases significantly - potentially triggering thermal shutdown at currents well below 1.5 A under ambient conditions above 60°C.
Can NCV59152MNADJTYG be used in parallel to increase output current?
No, the NCV59152MNADJTYG is not designed for parallel operation. Its output stage lacks current-sharing circuitry, and mismatched reference voltages or PCB trace impedances would cause unequal current distribution - risking thermal runaway or premature failure of one device. Use a single higher-current regulator instead.
What protection features are integrated into NCV59152MNADJTYG?
The NCV59152MNADJTYG integrates current limiting (2.0–3.0 A), thermal shutdown (activates at TJ >125°C), reverse output current protection (blocks current flow when VOUT > VIN by ≤6.5 V during shutdown), and open-collector error flag (active-low when VOUT falls below 95% nominal). All operate without external components.
