Product details
Overview
NCV8504PW25R2G from onsemi is a 250 mA low-dropout (LDO) linear regulator with fixed 2.5 V output, ±2% accuracy, 60 µA quiescent current, and thermal shutdown protection-designed for automotive body control modules requiring stable low-noise power under cold-crank conditions.
For engineers reviewing the NCV8504PW25R2G datasheet, pinout, applications, or equivalent options, key selection considerations include AEC-Q100 Grade 1 qualification, 45 V maximum input voltage, dropout voltage of 350 mV at 250 mA, reverse battery protection, and integrated overcurrent limiting.
Technical Context
The NCV8504PW25R2G implements a PNP-based pass transistor architecture enabling high PSRR (>70 dB at 1 kHz) and stable operation with ceramic output capacitors ≥1 µF. It integrates internal bandgap reference, error amplifier, and current-limit circuitry in a single die.
Designed specifically for automotive environments, it supports extended temperature range (−40 °C to +150 °C junction), withstands load dump transients up to 45 V per ISO 7637-2 Pulse 5a, and features active-low reset output with 200 ms delay for microcontroller supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% - ensures precise biasing for automotive MCUs and CAN transceivers. |
| Max Input Voltage | 45 V - sustains operation during ISO 7637-2 load dump events without external clamping. |
| Output Current | 250 mA - powers small microcontrollers, sensors, or interface ICs in distributed ECUs. |
| Quiescent Current | 60 µA - enables low-power sleep mode compliance in always-on vehicle networks. |
| Dropout Voltage | 350 mV @ 250 mA - maintains regulation down to 2.85 V input, critical for cold-crank (6 V) scenarios. |
| PSRR | 70 dB @ 1 kHz - suppresses alternator ripple and switching noise in sensitive analog signal chains. |
| Operating Temp | −40 °C to +150 °C - meets AEC-Q100 Grade 1 requirements for under-hood placement. |
Pinout & Package
NCV8504PW25R2G is housed in a thermally enhanced SOIC-8 (SOIC-W) package with exposed thermal pad (Package Code: PW). The package supports >1.5 W power dissipation at TA = 85 °C with standard 2-layer PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input supply connection | Accepts 3.5–45 V DC; requires local 1 µF ceramic capacitor for stability. |
| GND | Power ground reference | Low-impedance return path; tied to thermal pad for optimal heat transfer. |
| OUT | Regulated output node | Delivers 2.5 V ±2% to load; requires ≥1 µF ceramic output capacitor. |
| EN | Enable control input | Active-high logic; pulls low to disable regulator and reduce IQ to <1 µA. |
| RESET | Open-drain reset output | Asserts low when VOUT drops <92% of nominal; 200 ms delay prevents false resets. |
| NC | No connect | Internally unused; must be left floating or grounded per layout guidelines. |
| NC | No connect | Internally unused; must be left floating or grounded per layout guidelines. |
| EPAD | Exposed thermal pad | Must be soldered to large copper pour for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse battery protection | Withstands −40 V reverse polarity without damage-eliminates need for external series diode. |
| Integrated reset generator | Provides synchronized power-on reset with programmable delay, reducing BOM count vs discrete supervisor ICs. |
| Thermal shutdown with hysteresis | Shuts down at 170 °C and re-enables at 150 °C-prevents thermal runaway during overload or poor heatsinking. |
| Short-circuit foldback current limit | Limits output current to ~120 mA during short, reducing power dissipation and enabling self-recovery. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C ambient / −40 °C to +150 °C junction)-certified for automotive safety-critical subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73325PDBVR | 300 mA output, 50 µA IQ, but only AEC-Q100 Grade 3 (−40 °C to +85 °C ambient); no reset output or reverse battery protection. | Suitable for cabin interior modules only-not rated for under-hood use or load dump immunity. | Select if cost-sensitive and ambient temperature stays below 85 °C; verify external reset and reverse protection required. |
| TJA1044T/3 | Integrated CAN transceiver with embedded 2.5 V LDO (100 mA), no standalone regulator function; different pinout and system integration. | Used where CAN physical layer and local LDO are co-located-replaces two components but lacks flexibility. | Choose only when consolidating CAN PHY and LDO into single chip; not a drop-in replacement for NCV8504PW25R2G. |
Compared with TLV73325PDBVR and TJA1044T/3, the NCV8504PW25R2G provides full AEC-Q100 Grade 1 qualification, built-in reverse battery tolerance, and a dedicated reset output-making it uniquely suited for under-hood, safety-critical, and multi-rail automotive power domains where reliability and integration depth matter.

FAQ
What is the maximum input voltage rating for the NCV8504PW25R2G?
The NCV8504PW25R2G supports a maximum input voltage of 45 V, enabling operation during ISO 7637-2 load dump transients without external protection components. This rating is validated per AEC-Q100 stress testing and applies across the full operating temperature range of −40 °C to +150 °C junction temperature.
Does the NCV8504PW25R2G include reverse battery protection?
Yes, the NCV8504PW25R2G includes integrated reverse battery protection and can withstand −40 V applied to the IN pin without damage or latch-up. This eliminates the need for an external series diode in automotive battery-connected applications, reducing power loss and board space.
What is the purpose of the RESET pin on the NCV8504PW25R2G?
The RESET pin on the NCV8504PW25R2G is an open-drain output that asserts low when the regulated output falls below 92% of nominal (i.e., <2.3 V). It features a fixed 200 ms delay to prevent false resets during brief line transients, providing reliable power-on reset signaling to connected microcontrollers.
Is the NCV8504PW25R2G compatible with ceramic output capacitors?
Yes, the NCV8504PW25R2G is stable with ceramic output capacitors ≥1 µF and ESR <100 mΩ. Its internal compensation eliminates the need for high-ESR tantalum or aluminum electrolytic capacitors-reducing size, improving reliability, and supporting compact automotive PCB layouts.
What automotive qualification does the NCV8504PW25R2G meet?
The NCV8504PW25R2G is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C ambient / −40 °C to +150 °C junction), including stress tests for thermal cycling, humidity, and mechanical shock. It also complies with PPAP Level 3 documentation requirements for automotive production release.
