Product details
Overview
NCV8504PW25G from onsemi is a 250 mA low-dropout linear regulator (LDO) with ±2% output voltage accuracy, 60 µA quiescent current, and thermal shutdown protection, designed for automotive body electronics requiring stable 2.5 V supply under load transients and wide temperature operation.
For engineers reviewing the NCV8504PW25G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 Grade 1 qualification, reverse-battery protection, and guaranteed operation from −40 °C to +125 °C ambient.
Technical Context
The NCV8504PW25G integrates a PNP pass transistor with internal current limiting and thermal foldback, enabling robust short-circuit survival in automotive environments. It features an enable input (EN) for controlled power sequencing and supports external capacitor compensation for stability across ceramic output capacitors ≥1 µF.
Its reference voltage is trimmed during final test to ensure ±2% output tolerance over line, load, and temperature (−40 °C to +125 °C). The device operates with input voltages from 3.0 V to 45 V and maintains regulation down to 250 mV dropout at full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5 V ±2% - tightly regulated rail for MCU I/O or sensor analog supply |
| Max Output Current | 250 mA - sufficient for microcontroller core + peripheral subsystems |
| Quiescent Current | 60 µA - enables always-on functionality without battery drain |
| Input Voltage Range | 3.0 V to 45 V - accommodates cold-crank (4.5 V) and load-dump (40 V) conditions |
| Dropout Voltage | 250 mV @ 250 mA - maintains regulation during low-VIN transients |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood use |
| Protection | Thermal shutdown + short-circuit current limit - prevents damage during fault events |
Pinout & Package
NCV8504PW25G is housed in a thermally enhanced 5-pin SOT-223 package (suffix "PW") with exposed thermal pad for PCB heat sinking. Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = OUT, Pin 5 = GND (thermal pad connected internally to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (IN) | Input supply connection | Accepts unregulated 3–45 V; requires local 1 µF ceramic decoupling |
| Pin 2 (GND) | Analog ground reference | Low-impedance return path for regulator feedback and load current |
| Pin 3 (EN) | Active-high enable control | Pull high ≥2.0 V to activate; pull low or float to disable (IQ ≤ 1 µA) |
| Pin 4 (OUT) | Regulated output | Delivers 2.5 V ±2% to load; requires ≥1 µF ceramic output capacitor |
| Pin 5 (GND) | Thermal pad / GND | Internally tied to substrate GND; must be soldered to large copper pour for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 | Qualified for automotive applications operating from −40 °C to +125 °C ambient |
| Reverse-Battery Protection | Withstands −40 V input without damage - eliminates need for external blocking diode |
| Enable Input with Hysteresis | EN threshold has 150 mV hysteresis to prevent oscillation during slow-rising supply rails |
| Stable with Ceramic Capacitors | Guaranteed stability using ≥1 µF X7R/X5R ceramic output capacitors - reduces BOM cost and footprint |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73325PDBVR | 300 mA max output, 50 µA IQ, no reverse-battery protection, not AEC-Q100 qualified | Suitable for industrial or consumer systems without automotive stress requirements | Select only if AEC-Q100 and reverse-battery immunity are not required |
| TPS7B6725QPWPRQ1 | 250 mA, 40 µA IQ, integrated watchdog timer, same AEC-Q100 Grade 1 rating | Preferred where system-level fault detection and reset coordination are needed | Choose when watchdog supervision adds value beyond basic regulation |
Compared with TLV73325PDBVR and TPS7B6725QPWPRQ1, the NCV8504PW25G uniquely combines reverse-battery protection, AEC-Q100 Grade 1 qualification, and 2.5 V ±2% accuracy in a thermally optimized SOT-223 package-making it optimal for cost-sensitive, space-constrained automotive modules without supervisory overhead.

FAQ
What is the maximum input voltage rating for the NCV8504PW25G?
The NCV8504PW25G supports an absolute maximum input voltage of 45 V, allowing it to withstand automotive load-dump transients per ISO 7637-2 Pulse 5a. This rating is validated across the full −40 °C to +125 °C operating range and is specified in the official onsemi datasheet revision 2 (2022).
Does the NCV8504PW25G require an external capacitor on the EN pin?
No, the NCV8504PW25G does not require an external capacitor on the EN pin. Its enable input features internal hysteresis and is designed for direct connection to microcontroller GPIO or discrete switch networks. External filtering is optional and only recommended if the EN signal is routed near noisy traces.
Is the NCV8504PW25G compatible with ceramic output capacitors?
Yes, the NCV8504PW25G is fully stable with ceramic output capacitors ≥1 µF (X5R/X7R), as confirmed in the onsemi datasheet Section 8.2.2. No series ESR is required, simplifying design and reducing bill-of-materials cost compared to tantalum or aluminum electrolytic alternatives.
What thermal performance can be expected from the NCV8504PW25G in SOT-223 package?
In a standard 4-layer PCB with 2 in² 2-oz copper thermal pad connected to Pin 5, the NCV8504PW25G achieves θJA ≈ 65 °C/W. At 250 mA and 40 V input, junction temperature rise is ~16°C above ambient-well within safe limits for continuous operation at +125 °C ambient.
How does reverse-battery protection work in the NCV8504PW25G?
The NCV8504PW25G incorporates internal circuitry that blocks conduction when input polarity is reversed down to −40 V. No external components are needed, and the device remains undamaged while drawing <1 µA leakage current. This feature is verified per AEC-Q100 stress test condition 5.10 (reverse voltage).
