Product details
Overview
NCV8114BSN280T1G from onsemi is a 300 mA automotive-grade CMOS low-dropout linear regulator delivering 2.8 V output with ±1% accuracy, 135 mV typical dropout at full load, and 75 dB PSRR at 1 kHz-designed for noise-sensitive battery-powered systems including parking camera modules and infotainment subsystems.
For engineers reviewing the NCV8114BSN280T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 50 µA typical quiescent current, thermal shutdown and current limit protection, stable operation with 1 µF ceramic output capacitor, and TSOP-5 package compatibility with space-constrained PCB layouts.
Technical Context
The NCV8114BSN280T1G employs a PMOS pass transistor architecture enabling ultra-low dropout and reverse-current blocking. Its dynamic quiescent current adjustment maintains 50 µA IQ at no-load while scaling under load to sustain efficiency across operating conditions.
It integrates enable-controlled startup, thermal shutdown (160°C trip), foldback current limiting (600 mA typ), and stable regulation over −40°C to +125°C ambient-without requiring active discharge (confirmed by "B" suffix and ordering table indicating absence of discharge function).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±1% at room temperature - ensures precise rail generation for 2.8 V logic or sensor interfaces without external feedback. |
| Max Output Current | 300 mA continuous - supports moderate-power analog/RF blocks in automotive cameras and wireless modules. |
| Dropout Voltage | 170 mV typical at 300 mA (VOUT = 2.8 V) - enables regulation from 3.0 V input, critical for single-cell Li-ion or buck-fed systems. |
| Quiescent Current | 50 µA typical at no-load - extends battery life in always-on vehicle camera or telematics standby modes. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding the same board. |
| Operating Input Range | 1.7 V to 5.5 V - accommodates wide-input automotive supply rails and legacy 3.3 V/5 V domains. |
| Protection Features | Thermal shutdown (160°C), current limit (600 mA typ), and short-circuit robustness - eliminates need for external fault management circuitry. |
Pinout & Package
NCV8114BSN280T1G 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 enhanced thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 1.7–5.5 V; requires ≥1 µF ceramic capacitor close to pin for stability and transient immunity. |
| 2 - GND | Power ground reference | Primary return path; connects to exposed thermal pad - must be soldered to large copper area for thermal relief. |
| 3 - EN | Enable control input | Active-high logic: >0.9 V enables regulation; <0.4 V disables output and reduces IQ to 0.01 µA (no active discharge). |
| 4 - N/C | No-connect terminal | Not bonded; may be tied to GND to improve thermal dissipation without electrical impact. |
| 5 - OUT | Regulated output | Delivers stable 2.8 V; requires ≥1 µF X5R/X7R ceramic capacitor directly at pin for loop stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +125°C operation - meets automotive infotainment and ADAS environmental requirements. |
| Stable with 1 µF ceramic output cap | Eliminates need for larger or higher-ESR capacitors - reduces BOM count and PCB footprint in compact modules. |
| 75 dB PSRR @ 1 kHz | Rejects ripple from upstream switching regulators - preserves signal integrity in camera image sensors and RF receivers. |
| 50 µA typical quiescent current | Minimizes standby power loss - enables >1-year battery life in parking-assist cameras with periodic wake-up. |
| Integrated thermal & current protection | Self-protecting under overload or ambient overheating - avoids external reset supervision or fuse circuits. |
Applications
| Parking Camera Modules | Automotive Infotainment Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8114ASN280T1G | Includes active output discharge (100 Ω pull-down on OUT when disabled); otherwise identical specs and pinout. | Required where rapid output discharge prevents back-powering or bus contention during power sequencing. | Select NCV8114ASN280T1G only if active discharge is needed; NCV8114BSN280T1G is preferred for simpler, lower-cost designs without discharge requirement. |
| TLD1128-1EP | Higher 500 mA output, wider 3.5–40 V input range, integrated watchdog timer; not AEC-Q100 qualified. | Suitable for non-automotive industrial 12 V systems needing higher current and diagnostics - not drop-in for 2.8 V automotive rails. | Choose TLD1128-1EP only for 12 V–24 V industrial applications requiring watchdog functionality; not suitable for automotive AEC-Q100 compliance or low-input-voltage use cases. |
Compared with NCV8114ASN280T1G, the NCV8114BSN280T1G omits active discharge to reduce complexity and cost in applications where controlled ramp-down isn't required; versus TLD1128-1EP, it offers tighter accuracy, lower IQ, and automotive qualification at the expense of input voltage range and current capability.

FAQ
What is the output voltage tolerance of the NCV8114BSN280T1G over temperature?
The NCV8114BSN280T1G provides ±1% output voltage accuracy at room temperature. Over the full operating junction temperature range (−40°C to +125°C), the datasheet specifies ±2% to ±3% depending on output voltage bin - for the 2.8 V variant, this corresponds to ±3% (±84 mV) maximum deviation, confirmed in the Electrical Characteristics table under "Output Voltage Accuracy" for VOUT > 2.0 V.
Does the NCV8114BSN280T1G include active output discharge?
No, the NCV8114BSN280T1G does not include active output discharge. The "B" suffix explicitly denotes the version without this feature, as confirmed in the Ordering Information table and Pin Function Description section, which states that active discharge is present only in "NCV8114ASNyyyTCG" devices. The NCV8114BSN280T1G enters low-IQ shutdown but leaves the output floating.
What is the minimum output capacitor required for stability with the NCV8114BSN280T1G?
The NCV8114BSN280T1G is stable with a minimum 1 µF ceramic (X5R or X7R) output capacitor, as specified in both the Features list and Applications Information section. The device remains stable down to 0.22 µF to accommodate capacitance loss due to DC bias and temperature, but 1 µF is the recommended value for guaranteed performance across all conditions.
Can the NCV8114BSN280T1G operate from a 3.0 V input supply?
Yes, the NCV8114BSN280T1G can operate from a 3.0 V input. With a 2.8 V output and typical dropout of 170 mV at 300 mA, the minimum required input is ~2.97 V - well within its 1.7–5.5 V operating range. This makes it suitable for direct regulation from 3.0 V buck outputs or single-cell Li-ion (3.0–4.2 V) systems.
Is the NCV8114BSN280T1G pin-compatible with other variants in the NCV8114 family?
Yes, all NCV8114 variants - including NCV8114BSN280T1G, NCV8114ASN280T1G, and other voltage options - share identical TSOP-5 (Case 483) pinout and footprint. The pin assignments (IN, GND, EN, N/C, OUT) and mechanical dimensions are fully consistent across the family, enabling voltage-option flexibility without PCB redesign.
