Product details
Overview
NCV8501D80R2G from onsemi is an automotive-grade micropower LDO linear regulator with fixed 8.0 V output, ±2.0% accuracy, 150 mA output current capability, and integrated ENABLE, RESET (with programmable DELAY), and FLAG monitor functions. It operates down to 1.0 V output during RESET assertion and withstands +60 V load dump transients-designed for battery-powered microprocessor systems in harsh automotive environments.
For engineers reviewing the NCV8501D80R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its low 90 µA quiescent current at light load, 0.6 V max dropout at 150 mA, early-warning FLAG functionality, RESET validity down to 1.0 V, and SOIC-8 NB (Case 751-07) automotive-qualified packaging.
Technical Context
The NCV8501D80R2G implements a bandgap-referenced error amplifier with thermal shutdown, reverse-battery protection (−15 V), short-circuit limiting, and load-dump tolerance (+60 V peak). Its RESET circuit uses hysteresis (0.97×/0.98× VOUT thresholds) and remains functional even when VOUT drops to 1.0 V-enabling reliable power-up sequencing and brownout detection in automotive ECUs.
The FLAG monitor compares MON pin voltage against a 1.20 V internal reference (±100 mV hysteresis); when configured with external resistor divider, it provides early warning before RESET activation. ENABLE supports direct battery connection with built-in overvoltage protection and a typical 2.55 V turn-on threshold at +20 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 8.0 V ±2.0% - ensures stable MCU core/peripheral supply under temperature and line/load variation. |
| Max Output Current | 150 mA - sufficient for low-power microcontrollers, sensors, and CAN transceivers without external pass devices. |
| Dropout Voltage | 600 mV max at 150 mA - enables operation from 8.6 V input (e.g., cold-crank 9 V battery) while maintaining regulation. |
| Quiescent Current | 90 µA at 100 µA load - extends battery life in always-on automotive modules (e.g., body control units). |
| RESET Threshold | 7.00 V (low) / 7.52 V (high) - provides 6% hysteresis for noise-immune brownout detection at 8.0 V output. |
| FLAG Monitor Threshold | 1.20 V on MON pin - allows programmable early-warning trip point via external resistor divider for graceful shutdown. |
| Operating Input Range | −15 V to +45 V - supports reverse-battery protection and 46 V load dump survival per ISO 7637-2. |
Pinout & Package
NCV8501D80R2G is housed in an SOIC-8 NB (Case 751-07) package - 4.9 mm × 3.9 mm × 1.5 mm, Pb-free, with gull-wing leads optimized for automotive reflow and mechanical robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Input voltage supply | Accepts −15 V to +45 V; includes internal protection against reverse battery and load dump transients. |
| 2 - MON | Monitor input for FLAG comparator | Reference point for early-warning threshold; connect to VOUT via resistor divider to set custom flag point. |
| 3 - ENABLE | Active-high enable control | Powers up regulator when ≥2.55 V applied; internal pull-down ensures safe default-off state. |
| 4 - DELAY | RESET timing capacitor node | Sinks/source ~2.5 µA to external capacitor to program RESET delay time (e.g., 33 nF → ~24 ms). |
| 5 - GND | Power ground reference | All ground pins must be connected to system ground plane; critical for RESET/FLAG accuracy and thermal performance. |
| 6 - RESET | Open-collector reset output | Asserts low when VOUT falls below threshold; valid down to VOUT = 1.0 V for fail-safe microprocessor reset. |
| 7 - FLAG | Open-collector early-warning output | Drives low before RESET to signal microprocessor to complete pending tasks prior to shutdown. |
| 8 - VOUT | Regulated 8.0 V output | Delivers ±2.0% accurate, low-noise 8.0 V at up to 150 mA; requires 10 µF output capacitor for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | NCV prefix confirms AEC-Q100 stress testing, site/change control, and extended −40 °C to +150 °C junction operation. |
| Early-warning FLAG monitor | Provides programmable pre-reset alert via MON pin, enabling deterministic microprocessor shutdown sequence. |
| Load-dump tolerant design | Withstands +60 V transient spikes at VIN (per ISO 7637-2 Pulse 5a), eliminating need for external TVS in many ECU designs. |
| Low-IQ sleep mode | Draws only 12–30 µA when ENABLE = 0 V - ideal for always-on vehicle modules requiring ultra-low standby power. |
| Integrated RESET with DELAY | Programmable delay (via external capacitor) prevents false resets during startup transients and enables configurable timeout. |
Applications
| Body Control Module (BCM) | Instrument Cluster Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73380PDBVR | 8.0 V fixed, 300 mA, 225 mV dropout, 65 µA IQ - no RESET/FLAG/DELAY; SOT-23-5 package. | Lacks integrated monitoring and reset functions; suitable only where external supervision is already present. | Select when board space is constrained and system-level reset logic exists; not drop-in for NCV8501D80R2G's automotive safety features. |
| TPS7B6750QPWPRQ1 | 5.0 V fixed, 450 mA, 400 mV dropout, 120 µA IQ - includes RESET but no FLAG/DELAY; HTSSOP-16 package. | Lower output voltage; no early-warning capability; higher current but incompatible pinout and voltage option. | Consider only if redesigning for 5.0 V rail and accepting loss of FLAG-based graceful shutdown capability. |
Compared with TLV73380PDBVR and TPS7B6750QPWPRQ1, the NCV8501D80R2G uniquely combines fixed 8.0 V output, automotive qualification, integrated FLAG/RESET/DELAY, and ultra-low IQ in SOIC-8 - making it irreplaceable for legacy 8 V–based ECU architectures requiring self-contained power supervision.

FAQ
What is the output voltage tolerance and load regulation performance of the NCV8501D80R2G?
The NCV8501D80R2G delivers a fixed 8.0 V output with ±2.0% initial accuracy over temperature and line conditions. Load regulation is ±30 mV across 5.0 mA to 150 mA output current at constant VIN, ensuring stable voltage delivery to sensitive microcontrollers and analog circuits under dynamic load changes.
How does the FLAG monitor function work in the NCV8501D80R2G, and what is its typical trip point?
The FLAG monitor in the NCV8501D80R2G compares the voltage on the MON pin against an internal 1.20 V bandgap reference. When MON falls below this threshold (e.g., due to falling VOUT), FLAG pulls low to warn the microprocessor. Hysteresis of 20–100 mV prevents chatter, and the trip point is programmable using a resistor divider from VOUT to MON.
Can the NCV8501D80R2G operate during automotive load dump events, and what protection features does it include?
Yes, the NCV8501D80R2G is rated for +60 V peak transient voltage per ISO 7637-2 Pulse 5a and includes integrated protection against reverse battery (−15 V), short-circuit, and thermal overload. These features eliminate the need for external TVS diodes or fuses in most automotive ECU designs, reducing BOM cost and PCB area.
What is the minimum input voltage required for the NCV8501D80R2G to maintain regulation at full 150 mA load?
With a maximum dropout voltage of 600 mV at 150 mA, the NCV8501D80R2G requires a minimum input voltage of 8.6 V to sustain regulated 8.0 V output at full load. This allows reliable operation during engine cranking (e.g., 9 V battery sag) and cold-start conditions common in 12 V automotive systems.
Is the NCV8501D80R2G pin-compatible with other members of the NCV8501 family, such as adjustable or different voltage variants?
Yes, all SOIC-8 variants of the NCV8501 family-including NCV8501D80R2G, NCV8501D50R2G, and NCV8501DADJR2G-share identical pinout and footprint. However, fixed-output versions use PIN 4 as DELAY, while the adjustable version uses PIN 4 as NC and PIN 7 as VADJ; thus, PCB layout must match the specific variant's function mapping.
