Product details

Overview

NCV8504PW25R2 from onsemi is a 2.5 V fixed-output, 300 mA low-dropout (LDO) linear regulator in a 5-pin TSOP-5 package, featuring ±2% output voltage accuracy, 60 µA quiescent current, and thermal shutdown protection; it powers automotive microcontroller core logic and sensor interfaces requiring stable low-noise supply.

For engineers reviewing the NCV8504PW25R2 datasheet, pinout, applications, or equivalent options, key selection criteria include automotive-grade AEC-Q100 qualification, dropout voltage under 300 mV at full load, reverse polarity protection, and guaranteed operation from −40 °C to +150 °C junction temperature.

Technical Context

The NCV8504PW25R2 integrates a PNP pass transistor with internal current limiting and thermal foldback, enabling robust short-circuit survival without external components. Its feedback loop is internally compensated for stability with 1 µF ceramic output capacitance.

Designed specifically for automotive body electronics, it supports input voltages from 3.5 V to 45 V and maintains regulation during cold-crank (down to 3.2 V input), with built-in reverse-battery protection eliminating need for external diode.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.5 V ±2% - ensures precise biasing of ADC reference inputs and MCU I/O domains.
Max Output Current	300 mA - sufficient to power dual-core automotive MCUs or multiple CAN/LIN transceivers simultaneously.
Dropout Voltage	270 mV @ 300 mA - enables regulation during 12 V battery sag to 3.5 V, critical for cold-crank operation.
Quiescent Current	60 µA @ no load - minimizes standby power loss in always-on vehicle modules like door controllers.
Operating Temp Range	−40 °C to +150 °C (T_J) - meets AEC-Q100 Grade 1 requirements for under-hood placement.
Input Voltage Range	3.5 V to 45 V - accommodates 12 V and 24 V systems, including load-dump transients up to 41 V.

Pinout & Package

NCV8504PW25R2 uses a 5-pin TSOP-5 (SOT-23-5 compatible outline) thermally enhanced surface-mount package with exposed die pad for improved heat dissipation in high-ambient automotive environments.

Pin/Terminal	Circuit Role	Design Meaning
IN	Input Supply	Accepts unregulated 3.5–45 V; connects directly to battery rail via EMI filter.
GND	Ground Reference	Power ground return path; tied to exposed pad for thermal conduction and noise reduction.
OUT	Regulated Output	Delivers stable 2.5 V to load; requires ≥1 µF X7R ceramic capacitor for stability.
EN	Enable Control	Active-high logic input; pulls low to shut down regulator and reduce I_Q to 1 µA.
ADJ/SENSE	Voltage Feedback	Internally connected to 2.5 V reference; not user-accessible-fixed-output configuration.

Key Features

Feature	Design Value
Reverse Battery Protection	Withstands −40 V input without damage or external diode, reducing BOM count in 12 V automotive designs.
Thermal Shutdown with Hysteresis	Activates at 170 °C T_J, releases at 150 °C-prevents thermal runaway during sustained overload.
AEC-Q100 Qualified	Grade 1 (−40 °C to +125 °C ambient) with stress testing per automotive reliability standards.
Low-Noise Output	40 µV_RMS output noise (10 Hz–100 kHz) - suitable for precision analog front-ends and reference supplies.

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, 2.5 V fixed, 65 µA I_Q, but only rated to +125 °C T_J; no AEC-Q100 qualification.	Suitable for industrial or consumer use; lacks automotive transient immunity and extended temperature validation.	Select when cost sensitivity outweighs automotive qualification requirements.
TPS7B8125QDCYRQ1	250 mA, 2.5 V fixed, 25 µA I_Q, AEC-Q100 Grade 1, but higher 300 mV dropout at full load.	Better ultra-low-power performance; lower max current limits use in high-drive sensor clusters.	Prefer where standby current <30 µA is mandatory and peak load stays below 250 mA.

Compared with TLV73325PDBVR and TPS7B8125QDCYRQ1, the NCV8504PW25R2 uniquely balances automotive qualification, 300 mA capability, and cold-crank resilience-making it optimal for body electronics where both reliability and drive strength are non-negotiable.

FAQ

What is the maximum input voltage rating for the NCV8504PW25R2?

The NCV8504PW25R2 supports an absolute maximum input voltage of 45 V, with guaranteed operation up to 41 V during load-dump transients per ISO 7637-2 Pulse 5a. This rating allows direct connection to 12 V and 24 V automotive battery rails without external clamping circuitry.

Does the NCV8504PW25R2 require an external capacitor for stability?

Yes, the NCV8504PW25R2 requires a minimum 1 µF X7R ceramic capacitor at the output for loop stability. onsemi specifies this value in the datasheet and validates performance with 1–10 µF ceramics; tantalum or aluminum electrolytics are not recommended due to ESR-related instability risks.

Is the NCV8504PW25R2 pin-compatible with other devices in the NCV8504 family?

No-the NCV8504PW25R2 is a fixed 2.5 V variant in TSOP-5 packaging; adjustable versions (e.g., NCV8504PWADJR2) share the same pinout but require external resistor dividers on the ADJ pin, while different output voltage variants (e.g., NCV8504PW33R2) retain identical pin mapping and package.

What protection features does the NCV8504PW25R2 include?

The NCV8504PW25R2 integrates reverse-battery protection (−40 V tolerant), thermal shutdown with hysteresis, current limiting, and safe operating area (SOA) protection. It does not include overvoltage lockout or watchdog functionality-those require external supervision circuits.

Can the NCV8504PW25R2 be used in non-automotive applications?

Yes-the NCV8504PW25R2 functions reliably in industrial and medical applications requiring wide-input, low-noise 2.5 V regulation; however, its AEC-Q100 qualification adds cost and may be unnecessary unless operating in high-reliability, high-temperature, or vibration-prone environments where automotive-grade robustness is beneficial.
