Product details
Overview
NCV4299CD150R2G from onsemi is a precision automotive-grade low-dropout linear voltage regulator delivering 150 mA at 5.0 V ±2%, with maximum dropout of 0.5 V at 100 mA, quiescent current of 80 µA (ON mode), and AEC-Q100 Grade 1 qualification - deployed in engine control units, body electronics, and ADAS power rails where battery efficiency and load-dump resilience are critical.
For engineers reviewing the NCV4299CD150R2G datasheet, pinout, applications, or equivalent options, this page delivers verified SO-8 package mapping, reset timing parameters, inhibit logic behavior, thermal shutdown threshold (150 °C), and validated alternative options for automotive LDO replacement scenarios.
Technical Context
The NCV4299CD150R2G integrates a PNP pass transistor for ultra-low dropout operation, bandgap-referenced output regulation, and independent undervoltage detection circuitry that remains functional down to VQ = 1.0 V. Its reset function uses an internal 7.1 µA charge current into an external capacitor (D pin) to generate programmable delay (e.g., 28 ms with 100 nF).
It features dual monitoring paths: SI/SO comparator for early-warning signaling (trip threshold 1.36 V, hysteresis 90 mV), and RO open-collector NPN output with internal 20 kΩ pull-up to Q. The inhibit (INH) input enables full shutdown with <1.0 µA quiescent current, supported only in SO-14 variants - not present on the SO-8 NCV4299CD150R2G.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% - stable supply for MCU cores, CAN transceivers, and sensor interfaces under automotive line transients. |
| Max Dropout Voltage | 0.50 V at 100 mA - enables regulation down to VI = 5.5 V, supporting cold-crank operation in 12 V systems. |
| Quiescent Current | 80 µA typical at 100 µA load - extends battery life in always-on modules like door modules and telematics. |
| Reset Threshold | 4.67 V (typical), adjustable down to 3.5 V via RADJ resistor divider - allows precise brownout detection aligned with system MCU requirements. |
| Thermal Shutdown | 150 °C (typical) - protects against sustained overload or ambient overheating in enclosed ECUs without external thermal sensors. |
| Transient Immunity | Withstands 60 V peak load dump per ISO 16750-2 Class C - eliminates need for external TVS in front-end power conditioning. |
| ESD Rating | HBM: 2.0 kV; CDM: 1.0 kV - meets AEC-Q100 stress test requirements for robustness in manufacturing and field use. |
Pinout & Package
NCV4299CD150R2G is housed in a Pb-free SOIC-8 (SO-8, Case 751) package with 1.27 mm pitch, 5.0 mm × 4.0 mm footprint, and 1.75 mm max height. Internally fused leads enhance reliability in high-vibration automotive environments.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input Supply | Battery input (−40 V to 45 V); requires local 0.1 µF ceramic bypass to GND to suppress high-frequency noise. |
| 2 (SI) | Sense Input | Comparator input for early-warning monitor; threshold 1.36 V (±0.05 V), hysteresis 90 mV - connects to resistor divider from Q for custom trip point. |
| 3 (RADJ) | Reset Adjust | Adjusts RO reset threshold lower than default 4.67 V; connect to GND if unused - internal reference is 1.36 V. |
| 4 (D) | Reset Delay | Charges external capacitor (CD) at 7.1 µA; delay time td ≈ [CD × (1.85 V − 0.1 V)] / 7.1 µA - sets reset assertion hold-off. |
| 5 (GND) | Ground | Common return for regulator, reset, and sense circuits; multiple GND pins in SO-14 variant absent here - single GND required. |
| 6 (RO) | Reset Output | Open-collector NPN output with internal 20 kΩ pull-up to Q; asserts low when VQ falls below threshold - drives MCU RESET# directly. |
| 7 (SO) | Sense Output | Open-collector NPN output with internal 20 kΩ pull-up to Q; goes low before RO to signal impending reset - enables graceful firmware shutdown. |
| 8 (Q) | Regulated Output | 5.0 V ±2% @ 150 mA; requires ≥22 µF output capacitor with ESR ≤4 Ω for stability across −40 °C to 150 °C. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C junction), PPAP-capable - qualified for safety-critical power domains in production vehicles. |
| Ultra-Low Quiescent Current | 80 µA at 100 µA load - enables >10-year battery standby in keyless entry and tire pressure monitoring systems. |
| Programmable Reset Delay | Configurable via external CD capacitor (e.g., 28 ms with 100 nF) - prevents spurious resets during ignition transients. |
| Early-Warning Monitor | SI/SO path provides 1.6 µs warning window before RO assertion - allows microcontrollers to save state and disable peripherals prior to reset. |
| Robust Fault Protection | Integrated reverse-battery (−40 V), short-circuit, and thermal shutdown - eliminates need for discrete protection components in cost-sensitive designs. |
Applications
| Engine Control Unit (ECU) Power Rail | Body Control Module (BCM) Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73350PDBVR | 300 mA output, 250 mV dropout at 300 mA, no reset/sense functions, SOT-23-5 package. | Lacks RO/SO/RADJ/D pins - suitable only for basic regulation, not for reset-supervised systems. | Select when only voltage regulation is needed and board space is constrained; not a functional substitute for NCV4299CD150R2G's supervision features. |
| TPS7B6950QDCYRQ1 | 150 mA, 300 mV dropout, integrated watchdog timer, enable pin, but no SI/SO early-warning path. | Includes watchdog but omits analog sense monitor - cannot provide pre-reset warning for firmware cleanup. | Choose when system-level watchdog coverage is prioritized over component-level brownout warning; requires external circuit for early alert. |
Compared with TLV73350PDBVR and TPS7B6950QDCYRQ1, the NCV4299CD150R2G uniquely combines 5.0 V ±2% regulation, programmable reset delay, and dual-path (RO + SO) supervision in SO-8 - enabling both deterministic reset and graceful shutdown in a single device without external comparators or timers.

FAQ
What is the maximum input voltage rating for the NCV4299CD150R2G?
The NCV4299CD150R2G supports a continuous DC input voltage up to 45 V and withstands transient peaks up to 60 V per ISO 16750-2 Load Dump Test B. This rating applies across the full operating temperature range (−40 °C to +125 °C junction), making it suitable for 12 V automotive systems including start-stop and cold-crank conditions. The NCV4299CD150R2G does not require external clamping for standard load dump events.
Does the NCV4299CD150R2G include an inhibit (INH) pin?
No, the NCV4299CD150R2G in SO-8 package does not feature an inhibit pin. The INH function is available only on the SO-14 variant (e.g., NCV4299CD250R2G). The NCV4299CD150R2G relies on upstream switching or system-level power gating for full shutdown; its quiescent current remains at 80 µA in active regulation mode.
What output capacitor is required for stable operation of the NCV4299CD150R2G?
The NCV4299CD150R2G requires a minimum 22 µF output capacitor with ESR ≤4 Ω for guaranteed stability across −40 °C to +150 °C. Aluminum electrolytic or tantalum capacitors are recommended; ceramic capacitors with near-zero ESR may cause oscillation. The NCV4299CD150R2G datasheet confirms stability with 22 µF/4 Ω at 100 mA load and 13.5 V input.
How is the reset delay time calculated for the NCV4299CD150R2G?
The reset delay time (td) for the NCV4299CD150R2G is calculated using td ≈ [CD × (VUD − VD,sat)] / ID, where CD is the external capacitor on pin D, VUD = 1.85 V (upper delay threshold), VD,sat = 0.1 V (saturation voltage), and ID = 7.1 µA (typical charge current). For example, with CD = 100 nF, td ≈ 24.6 ms. The NCV4299CD150R2G's internal timing circuit ensures consistent delay across temperature and supply variations.
Can the NCV4299CD150R2G be used in non-automotive applications?
Yes, the NCV4299CD150R2G is technically suitable for industrial and medical applications requiring high-reliability 5.0 V regulation, low quiescent current, and reset supervision - but its AEC-Q100 qualification, 60 V transient rating, and automotive-focused thermal specs make it over-specified for most non-automotive use cases. Cost and availability favor industrial-grade alternatives unless automotive-grade robustness is explicitly required.
