Product details
Overview
NCV8502PDW100G from onsemi is a 10 V, ±2.0% accuracy automotive-grade LDO linear regulator with 150 mA output current, 0.6 V max dropout at full load, and integrated active RESET (operable down to 1.0 V output), FLAG early-warning monitor, and DELAY timing function. It is designed for battery-powered microprocessor systems requiring robust fault protection and precise power sequencing in harsh environments.
For engineers reviewing the NCV8502PDW100G datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SOIC-16 exposed-pad package details, automotive AEC-Q100 qualification status, and real-world design implications of its 90 µA quiescent current, 60 V peak transient tolerance, and adjustable reset threshold capability.
Technical Context
The NCV8502PDW100G implements a bandgap-referenced error amplifier with thermal shutdown, reverse-battery protection (−15 V), short-circuit current limiting (151–300 mA), and load-dump survivability up to +60 V. Its RESET circuit operates independently of regulation, ensuring validity even when VOUT drops to 1.0 V.
FLAG functionality uses an internal comparator referenced to 1.20 V (±0.11 V hysteresis) on the MON pin, enabling programmable early-warning thresholds via external resistor dividers. The DELAY pin sources 2.5 µA typical charge current to set reset delay time using an external capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 10.0 V ±2.0% - ensures stable MCU core or sensor supply within tight tolerance across temperature and load. |
| Max Output Current | 150 mA - sufficient for low-power microcontrollers, CAN transceivers, or automotive body control modules. |
| Dropout Voltage | 600 mV max at 150 mA - enables operation from 10.6 V input while maintaining regulation, critical for cold-crank scenarios. |
| Quiescent Current | 90 µA at 100 µA load - minimizes battery drain in always-on automotive modules like door controllers or telematics. |
| RESET Threshold | 8.50–9.40 V (0.97× to 0.98× VOUT) - provides hysteresis-stabilized brown-out detection with guaranteed operation down to VOUT = 1.0 V. |
| Transient Tolerance | +60 V peak (46 V load dump @ VIN = 14 V) - meets ISO 7637-2 Pulse 5a requirements for 12 V automotive systems. |
| Operating Temp | −40°C to +150°C junction - qualified for under-hood and transmission-control applications per AEC-Q100 Grade 1. |
Pinout & Package
NCV8502PDW100G is housed in a 16-lead SOIC wide-body package with exposed thermal pad (Case 751AG), optimized for high-power dissipation (RJA = 56°C/W, RJC = 15°C/W) and EMC robustness in automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply rail (−15 V to +48 V DC); withstands +60 V transients. |
| 2 | MON | Monitor input for FLAG comparator; threshold programmable externally (typ. 1.20 V). |
| 3–6, 9–12, 14–15 | NC | No internal connection; must be left unconnected or grounded per layout best practice. |
| 7 | GND | Power ground; all GND pins must be tied to common system ground plane. |
| 8 | MON | Duplicate MON pin - electrically identical to Pin 2; used for routing flexibility. |
| 9 | RADJ | Reset adjust input; connects to voltage divider from VOUT to set custom RESET threshold. |
| 10 | DELAY | Capacitor connection point for RESET timing; sources 2.5 µA typical charge current. |
| 11 | VOUT | Regulated 10 V output; requires ≥10 µF ceramic output capacitor for stability. |
| 12 | RESET | Open-collector active-low RESET signal; valid down to VOUT = 1.0 V. |
| 13 | FLAG | Open-collector early-warning output; asserts low before RESET to allow MCU graceful shutdown. |
| 14–16 | NC / Exposed Pad | Thermal pad (Pin 16) must be soldered to PCB copper pour for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 1 (−40°C to +125°C ambient) - certified for automotive powertrain and chassis applications. |
| Integrated FLAG Monitor | Provides programmable early-warning signal (via MON pin) to enable MCU task completion before RESET assertion. |
| Adjustable RESET Threshold | External resistor divider on RADJ pin allows custom reset voltage below default 9.2–9.4 V for 10 V output. |
| Robust Fault Protection | Combines −15 V reverse-battery tolerance, short-circuit current limit, thermal shutdown, and 60 V load-dump immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8502D100R2G | Same 10 V fixed output, but in SO-8 (Case 751) package with higher RJA = 165°C/W and no exposed pad. | Limited to lower-power applications (<50 mA continuous) due to thermal constraints; unsuitable for under-hood use above 85°C ambient. | Select when board space is constrained and thermal load is light; avoid for AEC-Q100 Grade 1 deployments. |
| TLV73310PDBVR | 10 V fixed LDO with 300 mA output, 250 mV dropout, but no RESET/FLAG/DELAY functions and only −40°C to +125°C rating. | Lacks automotive fault monitoring features; not AEC-Q100 qualified; requires external reset IC for sequencing. | Choose for cost-sensitive non-automotive applications where only basic regulation is needed and thermal margin is ample. |

FAQ
What is the minimum input voltage required for NCV8502PDW100G to regulate at 10 V output?
The NCV8502PDW100G requires VIN ≥ 10.6 V to maintain regulation at full 150 mA load, based on its 600 mV maximum dropout voltage. At light loads (100 µA), dropout drops to 150 mV, allowing regulation from as low as 10.15 V. This enables operation during automotive cold-crank conditions where battery voltage may dip to 6–7 V - but external pre-regulation would be needed in that case.
Does NCV8502PDW100G support adjustable output voltage?
No, NCV8502PDW100G is a fixed 10 V output variant. The "100" in the part number denotes 10 V output; adjustable versions use "ADJ" suffix (e.g., NCV8502PDWADJG). The NCV8502PDW100G has internal feedback and cannot be reconfigured for other voltages - its VADJ pin is not bonded out and is unused.
How is the RESET delay time calculated for NCV8502PDW100G?
The RESET delay time is set by an external capacitor on the DELAY pin and follows tDELAY = CDELAY × (VDT − VRESET_LOW) / ICHARGE, where VDT = 1.4–2.2 V (typ. 1.8 V), VRESET_LOW ≈ 0 V, and ICHARGE = 1.5–3.5 µA (typ. 2.5 µA). For example, a 33 nF capacitor yields ~23.8 ms delay. The NCV8502PDW100G does not include internal delay capacitance.
Can the FLAG output of NCV8502PDW100G drive a microcontroller GPIO directly?
Yes - the FLAG pin is an open-collector NPN output rated for 1 mA sink current and 0.4 V saturation voltage at 1 mA. It can directly interface with 3.3 V or 5 V MCU GPIOs using a pull-up resistor (typically 10 kΩ to VCC). The NCV8502PDW100G FLAG asserts low when MON voltage falls below 1.10–1.31 V, providing ≥100 µs warning before RESET activation.
Is NCV8502PDW100G pin-compatible with earlier NCV8502 variants in SO-8 packages?
No - NCV8502PDW100G uses a 16-lead SOIC wide-body exposed-pad package (Case 751AG), while SO-8 variants (e.g., NCV8502D100G) use Case 751. Pin count, pinout, thermal pad, and footprint are incompatible. Migration requires PCB redesign; however, electrical functionality (10 V output, RESET/FLAG behavior) remains consistent across the NCV8502 family.
