Product details
Overview
NCV612SQ50T2G from onsemi is an automotive-grade, fixed-output 5.0 V CMOS low-dropout linear regulator in SC70-5 package, delivering up to 100 mA output current with 40 µA typical quiescent current and 230 mV dropout at 100 mA - designed for battery-powered infotainment modules requiring stable low-power voltage regulation.
For engineers reviewing the NCV612SQ50T2G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 qualification, −40 °C to +125 °C operating range, ±2.0% output accuracy, SC70-5 thermal performance, and enable-controlled standby mode for power-sensitive automotive subsystems.
Technical Context
The NCV612SQ50T2G integrates a PMOS pass transistor, precision voltage reference, error amplifier, and protection circuitry (current limit, thermal shutdown) in a single die. Its ultra-low quiescent current stems from optimized biasing of internal analog blocks, enabling operation during vehicle sleep modes without excessive battery drain.
It operates as a fixed 5.0 V output LDO with active enable control: pulling Enable low disables regulation and reduces ground current to <1 µA, while connecting Enable to Vin enables full operation. Dropout behavior is characterized across temperature (−40 °C to +125 °C) and load (1–100 mA), with guaranteed 230 mV max at nominal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2.0% over −40 °C to +125 °C and 1–100 mA load - ensures compatibility with 5 V logic rails in automotive microcontrollers and sensors. |
| Max Output Current | 100 mA continuous - sufficient for powering MCU cores, CAN transceivers, or small display drivers in compact modules. |
| Quiescent Current | 40 µA typical at 10 mA load - enables >1-year battery hold-up in always-on vehicle telematics without significant self-discharge. |
| Dropout Voltage | 230 mV max at 100 mA and 5.0 V output - allows regulation from 5.23 V input, supporting wide-input battery-supplied systems with minimal headroom loss. |
| Enable Threshold | VTH(HI) = 0.95 V min, VTH(LO) = 0.3 V max - compatible with 1.8 V/3.3 V GPIOs and supports direct connection to microcontroller wake signals. |
| Thermal Range | −40 °C to +125 °C junction - validated for under-hood and dashboard-mounted applications per AEC-Q100 Grade 1 requirements. |
| Noise Performance | 100 µVRMS (100 Hz–100 kHz) - low enough to supply analog sensor front-ends or ADC references without added filtering. |
Pinout & Package
NCV612SQ50T2G is housed in the SC70-5 (SOT-353) surface-mount package - a 1.25 mm × 2.1 mm micro-miniature outline with 0.65 mm pitch, optimized for space-constrained automotive PCBs and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vin | Positive input supply rail - accepts 0–6.0 V; must be decoupled with ≥1.0 µF ceramic capacitor placed adjacent to pin. |
| 2 | Gnd | Power ground reference - requires low-impedance PCB plane connection to minimize noise coupling and thermal resistance. |
| 3 | Enable | Active-high digital control input - drives device into ultra-low-power standby (<1 µA IGND) when pulled below 0.3 V. |
| 4 | N/C | No internal connection - must remain unconnected; floating or tied to Gnd/Vin has no functional effect. |
| 5 | Vout | Regulated 5.0 V output - delivers up to 100 mA; requires ≥1.0 µF output capacitor for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Validated for automotive Grade 1 (−40 °C to +125 °C) operation with PPAP documentation support - meets OEM reliability requirements for body electronics. |
| Ultra-Low IQ | 40 µA typical quiescent current enables >10-year shelf life in battery-backed modules and supports ISO 16750-2 sleep-mode current budgets. |
| Low-ESR Cap Compatible | Stable with ceramic or tantalum output capacitors from 1.0 µF to >10 µF and ESR 0–5 Ω - eliminates need for specialized high-ESR capacitors in cost-sensitive designs. |
| Integrated Protection | Current limiting (600 mA short-circuit peak), thermal shutdown (~160 °C), and reverse-voltage safe operation - reduces external component count and system-level fault handling complexity. |
| Pb-Free & RoHS Compliant | SC70-5 package with matte tin lead finish - compliant with automotive ELV directive and JESD204B assembly standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8170ASN50T2G | Higher 200 mA output, 25 µA IQ, same SC70-5 package and 5.0 V output - but uses NMOS pass device with higher dropout (300 mV @ 100 mA). | Better for higher-current loads; less suitable for ultra-low-headroom inputs due to higher dropout. | Select when >100 mA is required and input headroom exceeds 300 mV; verify thermal derating at full load. |
| TLV73350PDBVR | 5.0 V, 300 mA, 65 µA IQ, SOT-23-5 package - wider input range (1.4–5.5 V), but not AEC-Q100 qualified and rated only to +105 °C. | Suitable for non-automotive portable electronics; lacks automotive qualification and extended temperature capability. | Choose for cost-sensitive industrial or consumer designs where AEC-Q100 and +125 °C are not mandatory. |
Compared with NCV612SQ50T2G, NCV8170ASN50T2G offers higher current but sacrifices dropout performance, while TLV73350PDBVR provides greater current and input flexibility at the expense of automotive qualification and thermal rating - making NCV612SQ50T2G the optimal choice for space-constrained, thermally demanding automotive LDO applications requiring strict low-IQ and AEC compliance.

FAQ
What is the maximum input voltage rating for the NCV612SQ50T2G?
The NCV612SQ50T2G has an absolute maximum input voltage (Vin) rating of 6.0 V. Exceeding this value may cause permanent damage. For reliable operation, the recommended input range is 5.23 V to 6.0 V to maintain regulation at full 100 mA load, given its 230 mV dropout specification. The device includes internal protection against overvoltage stress, but sustained operation above 6.0 V is not supported.
Does the NCV612SQ50T2G require external components to operate stably?
Yes - the NCV612SQ50T2G requires at minimum a 1.0 µF ceramic input capacitor (Cin) placed close to the Vin and Gnd pins, and a 1.0 µF ceramic output capacitor (Cout) connected directly to Vout and Gnd. These capacitors ensure stability, improve line/load transient response, and reduce output noise. Larger values (e.g., 2.2–10 µF) further enhance performance but are not mandatory for basic functionality.
Is the NCV612SQ50T2G pin-compatible with other variants in the NCV612 series?
Yes - all NCV612 variants including NCV612SQ50T2G share identical SC70-5 pinout, package dimensions, and terminal functions (Vin, Gnd, Enable, N/C, Vout). This allows drop-in replacement across output voltages (1.5 V to 5.0 V) without PCB layout changes, provided the enable logic and input/output decoupling meet target voltage requirements.
How does the Enable pin function on the NCV612SQ50T2G?
The Enable pin on the NCV612SQ50T2G is an active-high digital control input. When pulled to ≥0.95 V (relative to Gnd), the device regulates normally; when pulled to ≤0.3 V, it enters ultra-low-power standby with ground current reduced to <1 µA. If unused, Enable must be tied directly to Vin - floating the pin is not permitted and may cause erratic behavior.
What is the output voltage accuracy of the NCV612SQ50T2G over temperature and load?
The NCV612SQ50T2G maintains ±2.0% output voltage accuracy over the full automotive temperature range (−40 °C to +125 °C) and load current range (1 mA to 100 mA). At 25 °C and 10 mA load, the typical tolerance is tighter (±0.5%), but design margins must account for worst-case ±2.0% to ensure compatibility with downstream 5 V logic interfaces.
