Product details
Overview
NCV8501PDW50G from onsemi is a 5.0 V fixed-output automotive-grade LDO linear regulator in SOW-16 exposed pad package, delivering 150 mA output current with ±2.0% accuracy, 0.6 V max dropout at full load, and integrated active RESET (operable down to 1.0 V output), ENABLE, DELAY, and FLAG monitor functions. It is designed for battery-powered microprocessor systems requiring robust fault protection and early warning signaling in harsh environments.
For engineers reviewing the NCV8501PDW50G datasheet, pinout, applications, or equivalent options, key selection criteria include its 150 mA output capability, 90 µA quiescent current at light load, −15 V reverse voltage tolerance, +60 V peak transient immunity, and FLAG/RESET timing coordination for safe microprocessor shutdown sequencing.
Technical Context
The NCV8501PDW50G implements a bandgap-referenced error amplifier with thermal shutdown, current limiting, and reverse-battery protection. Its RESET circuit operates independently of regulation status and remains functional even when VOUT drops to 1.0 V, ensuring reliable system reset under brownout conditions.
The device integrates a programmable DELAY function (charged via internal 2.5 µA current source) and an open-collector FLAG output referenced to a 1.20 V typical MON threshold with 20–100 mV hysteresis - enabling precise early-warning signaling before RESET assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2.0% - ensures stable MCU core/logic supply within automotive AEC-Q100-compliant tolerance. |
| Max Output Current | 150 mA - sufficient for low-power microcontrollers, sensors, and interface ICs without external pass devices. |
| Dropout Voltage | 600 mV max at 150 mA - enables operation from 12 V battery with ≥5.6 V input during cold-crank transients. |
| Quiescent Current | 90 µA at 100 µA load - minimizes battery drain in always-on vehicle modules (e.g., body control units). |
| RESET Threshold | 4.50 V (low) / 4.70 V (high) - provides 4% hysteresis to prevent oscillation during slow VOUT recovery. |
| FLAG Threshold | 1.20 V on MON pin - allows configurable early-warning trip point using external resistor divider. |
| Transient Immunity | +60 V peak load dump, −15 V reverse battery - meets ISO 7637-2 Pulse 5a/b and reverse-polarity requirements. |
Pinout & Package
SOW-16 exposed pad (Case 751AG) with thermal pad for enhanced power dissipation; pin 16 is GND, pin 13 is VOUT, pin 7 is VIN, pin 1 is ENABLE, pin 8 is MON, pin 2 is FLAG, pin 16 is GND, pin 10 is DELAY, pin 6 is RESET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 7) | Input voltage supply | Accepts −15 V to +45 V DC; withstands +60 V load dump transients without damage. |
| MON (Pin 8) | Monitor comparator input | Configures FLAG trip point; connect to resistor divider from VOUT for adjustable early-warning threshold. |
| ENABLE (Pin 1) | Power enable control | Active-high logic; internal pull-down ensures safe default-off state; tolerates battery-line connection. |
| DELAY (Pin 10) | Reset delay capacitor node | Internal 2.5 µA current source charges external capacitor to set RESET assertion delay time. |
| GND (Pin 16) | Ground reference | All ground pins must be connected to PCB ground plane; exposed pad is electrically tied to GND. |
| RESET (Pin 6) | Open-collector reset output | Asserts low when VOUT falls below threshold; functional down to VOUT = 1.0 V for fail-safe operation. |
| FLAG (Pin 2) | Early-warning flag output | Open-collector output pulled low when MON voltage crosses threshold - signals impending RESET. |
| VOUT (Pin 13) | Regulated output | 5.0 V ±2.0% output capable of sourcing 150 mA; requires ≥10 µF output capacitor for stability. |
Key Features
| Feature | Design Value |
|---|---|
| NCV prefix | Indicates automotive qualification with site and change control - required for AEC-Q100-compliant designs. |
| Integrated FLAG monitor | Provides programmable early-warning signal (via MON pin) to allow microprocessor task completion before RESET. |
| Delay-programmable RESET | External capacitor on DELAY pin sets precise reset timeout - eliminates need for discrete RC timing networks. |
| Robust fault protection | Combines reverse-battery (−15 V), short-circuit, thermal overload, and +60 V load dump immunity in single package. |
| Pb-Free SOW-16 E-Pad | Exposed thermal pad improves RJA to 56 °C/W - supports higher ambient temperatures in engine bay applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8501D50G | SO-8 package (RJA = 165 °C/W), no exposed thermal pad, same electrical specs. | Limited to lower ambient temperatures (<85 °C) and lower continuous power dissipation. | Select when board space is constrained and thermal load is light; not suitable for under-hood use. |
| TLV73350PDBVR | Lower IQ (45 µA), smaller SOT-23-5 package, no RESET/FLAG/DELAY functions, ±1.5% accuracy. | Designed for cost-sensitive consumer applications - lacks automotive fault protection and monitoring features. | Choose only for non-automotive, non-safety-critical designs where feature set reduction is acceptable. |

FAQ
What is the minimum input voltage required for NCV8501PDW50G to regulate 5.0 V output?
The NCV8501PDW50G requires VIN ≥ 5.6 V to maintain regulation at full 150 mA load, based on its 600 mV maximum dropout voltage. At lighter loads, regulation begins at VIN ≥ 5.15 V (typical 150 mV dropout). Input voltage must remain above absolute minimum ratings (−15 V to +45 V) and avoid exceeding 60 V transient peaks.
How does the FLAG function of NCV8501PDW50G differ from the RESET function?
The FLAG output of NCV8501PDW50G provides early warning - it asserts low when the MON pin voltage crosses ~1.20 V, indicating VOUT is approaching the RESET threshold. RESET asserts later, only when VOUT drops below 4.50 V (low threshold). This two-stage signaling gives the microprocessor time to complete critical tasks before hard reset.
Can NCV8501PDW50G be used without connecting the DELAY pin?
Yes - the DELAY pin of NCV8501PDW50G may be left unconnected for immediate RESET assertion upon undervoltage detection. However, doing so eliminates the programmable delay feature; for controlled reset timing, a capacitor (e.g., 33 nF for ~24 ms delay) must be connected between DELAY and GND.
What is the thermal performance advantage of the SOW-16 exposed pad package in NCV8501PDW50G?
The SOW-16 exposed pad package of NCV8501PDW50G achieves RJA = 56 °C/W (vs. 165 °C/W for SO-8), reducing junction temperature rise by >60% under identical load. This enables reliable operation at 125 °C ambient in engine compartment applications where the SO-8 variant would thermally throttle or shut down.
Is NCV8501PDW50G qualified for automotive applications?
Yes - NCV8501PDW50G carries the NCV prefix, confirming it is manufactured under automotive-specific quality controls (AEC-Q100 stress testing, PPAP documentation, and change notification protocols), and is rated for −40 °C to +150 °C junction temperature - meeting requirements for under-hood and safety-critical ECUs.
