Product details
Overview
NCV8114BSN150T1G from onsemi is a 300 mA automotive-grade CMOS low-dropout linear regulator delivering 1.5 V output with ±1% accuracy, 150 mV typical dropout at full load, and 75 dB PSRR at 1 kHz - designed for noise-sensitive battery-powered infotainment and camera modules.
For engineers reviewing the NCV8114BSN150T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 50 µA typical quiescent current, TSOP-5 package compatibility, thermal shutdown protection, and absence of active output discharge (distinguishing it from ASN-series variants).
Technical Context
The NCV8114BSN150T1G uses a PMOS pass transistor architecture enabling ultra-low dropout and reverse-current blocking. Its dynamic quiescent current adjustment maintains 50 µA IQ across input voltage range (1.7–5.5 V), while internal thermal shutdown (160°C) and current limiting (600 mA typ.) ensure robust operation in automotive ambient conditions (−40°C to +125°C).
Unlike the ASN-series, this BSN variant omits active output discharge - confirmed by datasheet ordering table and functional description - and relies solely on natural RC decay during disable. Stability is guaranteed with ≥1 µF ceramic output capacitor and no ESR requirement, supporting compact 0402 layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±1% at room temperature - ensures precise core logic or sensor biasing without external feedback. |
| Max Output Current | 300 mA continuous - supports moderate-power microcontrollers or interface ICs in space-constrained modules. |
| Dropout Voltage | 150 mV typical at 300 mA - enables regulation from 1.65 V input, critical for single-cell Li-ion or LiFePO₄ systems. |
| Quiescent Current | 50 µA typical at no-load - extends battery life in always-on parking camera or telematics subsystems. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters in infotainment head units. |
| Operating Temp | −40°C to +125°C junction - validated for under-hood or dashboard-mounted automotive applications. |
| Protection | Thermal shutdown (160°C) and current limit (600 mA typ.) - prevents latch-up or damage during fault conditions. |
Pinout & Package
NCV8114BSN150T1G is housed in a Pb-free TSOP-5 (Case 483) package measuring 3.00 × 1.50 × 0.95 mm with 0.95 mm pitch. The exposed pad is internally connected to GND for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input supply connection | Accepts 1.7–5.5 V; requires ≥1 µF ceramic decoupling close to pin to suppress trace inductance during load transients. |
| 2 - GND | Power ground reference | Primary return path; must be tied directly to PCB ground plane and thermally coupled to exposed pad. |
| 3 - EN | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and reduces IQ to 0.01 µA - no active discharge. |
| 4 - N/C | No-connect terminal | Internally unconnected; may be grounded to improve thermal dissipation but has no electrical function. |
| 5 - OUT | Regulated output | Delivers stable 1.5 V; requires ≥1 µF X5R/X7R ceramic capacitor to ground for stability across temperature and bias. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Validated for automotive applications including infotainment and ADAS camera modules per Grade 1 requirements. |
| Low-noise regulation | 70 µVrms output noise (10 Hz–100 kHz) - suitable for analog sensors and RF front-end power domains. |
| Ultra-low IQ | 50 µA typical at zero load - enables >1-year battery standby in always-on vehicle monitoring systems. |
| Stable with minimal capacitance | Guaranteed stability with 1 µF ceramic COUT - eliminates need for larger, costly tantalum or polymer capacitors. |
| Robust protection suite | Integrated thermal shutdown, current limit, and reverse-voltage blocking via PMOS body diode - reduces external protection components. |
Applications
| Parking Camera Module | Automotive Infotainment SoC Core Rail |
|---|---|
Use Scenario: Powering image signal processor and CIS in rear-view camera systems operating from 12 V battery via intermediate buck converter.

Use Scenario: Supplying 1.5 V core voltage to application processors in head unit systems requiring AEC-Q100 compliance and extended temperature support. IC Role / Device Role / Timing Role: Secondary LDO post-regulator ensuring tight voltage tolerance and fast transient response for SoC core domains. Use Value: ±1% accuracy maintains CPU timing margins; 300 mA capacity supports burst-mode processing without droop; thermal shutdown prevents failure during prolonged high-CPU-load scenarios. |
| Wireless Telematics Node | ADAS Sensor Interface Power |
Use Scenario: Powering LTE/Wi-Fi/BLE combo module in vehicle-to-cloud communication units where low standby power is mandatory. IC Role / Device Role / Timing Role: Always-on 1.5 V rail enabling rapid wake-from-sleep transitions while minimizing battery drain. Use Value: 50 µA quiescent current extends 10-year battery life in sealed telematics units; EN pin allows host MCU to gate power during deep sleep. |
Use Scenario: Providing regulated 1.5 V to high-speed serializer/deserializer (SerDes) interfaces in radar or camera fusion ECUs. IC Role / Device Role / Timing Role: Low-noise auxiliary rail for SerDes PHY layers sensitive to supply-induced jitter. Use Value: 70 µVrms noise floor minimizes bit error rate; 1 µF ceramic stability simplifies layout in dense multi-layer ADAS PCBs with strict EMI constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8114ASN150T1G | Includes active output discharge (100 Ω pull-down on OUT when disabled); otherwise identical specs. | Required where rapid output discharge is needed to prevent back-powering or sequencing conflicts. | Select ASN variant only if active discharge is explicitly required; BSN avoids unintended discharge in systems relying on natural decay. |
| TLV73315PDBVR | 300 mA, 1.5 V fixed, 250 mV dropout (typ), 40 µA IQ, SOT-23-5 package - not AEC-Q100 qualified. | Suitable for industrial or consumer portable devices, not automotive safety-critical systems. | Choose TLV73315PDBVR for cost-sensitive non-automotive designs; NCV8114BSN150T1G is mandatory for AEC-Q100-compliant vehicle platforms. |
Compared with NCV8114ASN150T1G, the NCV8114BSN150T1G trades active discharge capability for simpler enable behavior and identical regulation performance; versus TLV73315PDBVR, it adds automotive qualification and lower dropout at the expense of slightly higher IQ and larger footprint.

FAQ
What is the dropout voltage specification for NCV8114BSN150T1G at 300 mA load?
The NCV8114BSN150T1G exhibits a typical dropout voltage of 150 mV at 300 mA output current and 1.5 V nominal output, as specified in the Electrical Characteristics table under "Dropout Voltage" test condition VOUT = 1.5 V. This value ensures reliable regulation from input voltages as low as 1.65 V, critical for automotive cold-crank scenarios.
Does NCV8114BSN150T1G include active output discharge functionality?
No, the NCV8114BSN150T1G does not include active output discharge. Per the datasheet ordering table and Applications Information section, only ASN-series variants (e.g., NCV8114ASN150T1G) feature this function. The BSN variant relies on natural RC decay when disabled, confirmed by absence of RDIS parameter and explicit "Without output active discharge function" labeling.
What is the minimum output capacitor required for stable operation of NCV8114BSN150T1G?
The NCV8114BSN150T1G is stable with a minimum 1 µF ceramic (X5R or X7R) output capacitor, as stated in both the Features list and Applications Information section. The device remains stable across temperature, DC bias, and package size variations down to an effective capacitance of 0.22 µF - supporting compact 0402 MLCC implementations.
Is NCV8114BSN150T1G qualified to AEC-Q100 standards?
Yes, the NCV8114BSN150T1G is AEC-Q100 qualified and PPAP capable, as explicitly noted in the Features section and reinforced by the "NCV" prefix designation indicating automotive and other applications requiring unique site and control change requirements.
What is the enable pin threshold behavior for NCV8114BSN150T1G?
The NCV8114BSN150T1G EN pin has a guaranteed high threshold of 0.9 V (min) and low threshold of 0.4 V (max), with hysteresis between rising and falling edges. Driving EN above 0.9 V enables regulation; pulling EN below 0.4 V disables the output and reduces quiescent current to 0.01 µA, as verified in the Pin Function Description and Electrical Characteristics tables.
