Product details
Overview
NCV612SQ30T1G from onsemi is an automotive-grade CMOS low-dropout linear voltage regulator delivering a fixed 3.0 V output at up to 100 mA, featuring ultra-low 40 µA quiescent current, 230 mV dropout at full load, and AEC-Q100 qualification for use in battery-powered infotainment modules and body control units.
For engineers reviewing the NCV612SQ30T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its −40 °C to +125 °C operating range, SC70-5 package footprint, enable-controlled standby mode, and compatibility with low-ESR ceramic output capacitors without stability compensation.
Technical Context
The NCV612SQ30T1G integrates a PMOS pass transistor, precision voltage reference, error amplifier, and thermal/overcurrent protection circuits - enabling stable regulation with minimal external components. Its architecture supports fast load transient response (<100 µs recovery) and high PSRR (≥60 dB at 1 kHz) due to internal biasing and feedback loop optimization.
Designed specifically for automotive subsystems, it uses an enable input to achieve deep-sleep current draw (≤0.03 µA), while maintaining ±2.0% output voltage accuracy across temperature and line/load variations. The device operates with input voltages from 3.3 V to 6.0 V and requires only 1.0 µF input and output ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2.0% over −40 °C to +125 °C and 1–100 mA load - ensures stable MCU core supply under wide thermal and dynamic conditions. |
| Dropout Voltage | 230 mV at 100 mA - enables operation from 3.3 V input (e.g., automotive 3.3 V rail) with margin for brownout resilience. |
| Quiescent Current | 40 µA typical at 10 mA load - extends battery life in always-on vehicle modules such as door controllers or sensor nodes. |
| Enable Threshold | VEN(HI) = 0.95 V min, VEN(LO) = 0.3 V max - compatible with 1.8 V/3.3 V logic without level-shifting circuitry. |
| Thermal Protection | Internal shutdown at ~160 °C - prevents latch-up or permanent damage during sustained overload or poor PCB thermal design. |
| Input Voltage Range | 0 to 6.0 V - supports direct connection to 5 V or 3.3 V system rails and accommodates transient spikes up to 6 V. |
| Output Noise | 100 µVRMS (100 Hz–100 kHz) - suitable for noise-sensitive analog sensors and RF front-end power domains. |
Pinout & Package
Housed in the SC70-5 (SOT-353) surface-mount package - 2.2 mm × 1.35 mm footprint 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 | Accepts unregulated input (3.3–6.0 V); must be decoupled with ≥1.0 µF ceramic capacitor placed adjacent to pin. |
| 2 - Gnd | Power ground reference | Low-impedance return path for both input and output currents; requires solid copper pour beneath package for thermal and noise performance. |
| 3 - Enable | Active-high enable control | Pull high to Vin to activate regulator; pull ≤0.3 V to disable and reduce ground current to ≤0.03 µA - enables system-level power sequencing. |
| 4 - N/C | No internal connection | Unbonded terminal - must remain floating; no routing or soldering required. |
| 5 - Vout | Regulated output | Delivers stable 3.0 V to load; requires ≥1.0 µF ceramic output capacitor with ESR ≤5 Ω for guaranteed stability and transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Qualified to Grade 1 (−40 °C to +125 °C ambient), PPAP-capable - meets automotive reliability and traceability requirements for Tier 1 production. |
| Ultra-low IQ | 40 µA typical at 10 mA load - reduces parasitic drain in parked-vehicle scenarios where microamps determine battery runtime. |
| SC70-5 package | Micro-miniature 5-pin footprint (2.2 × 1.35 mm) - enables placement near SoCs or MCUs in tight-layout ADAS camera modules or telematics units. |
| Ceramic capacitor compatible | Stable with 1.0 µF X5R/X7R ceramics (no ESR minimum) - eliminates need for tantalum or aluminum electrolytics, improving long-term reliability and reducing BOM count. |
| Integrated protection | Thermal shutdown + current limit (600 mA short-circuit) - prevents field failures during wiring faults or downstream component shorts without external circuitry. |
Applications
| Infotainment Power Rail | Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73330PDBVR | 300 mA output, 250 mV dropout at 300 mA, 55 µA IQ, SOT-23-5 package (larger than SC70-5) | Higher current capability but larger footprint and higher quiescent current - better for non-space-constrained industrial designs needing >100 mA. | Select when higher output current or wider input range (1.4–5.5 V) is required; not pin-compatible with NCV612SQ30T1G. |
| TPS78030QDDCRQ1 | AEC-Q100 Grade 1, 200 mA, 170 mV dropout at 200 mA, 500 nA IQ in shutdown, same SC70-5 package | Lower IQ in shutdown but higher active IQ (1.3 µA vs. 40 µA); tighter initial accuracy (±0.5%) but higher cost. | Prefer when ultra-low shutdown current is critical and board area permits same-footprint upgrade; not drop-in due to different enable logic and biasing. |
Compared with TLV73330PDBVR and TPS78030QDDCRQ1, the NCV612SQ30T1G offers the optimal balance of ultra-low active quiescent current, automotive qualification, and minimal SC70-5 footprint - making it uniquely suited for cost- and space-sensitive 100 mA automotive subsystems where standby efficiency and thermal robustness are prioritized over maximum output current or sub-µA shutdown.

FAQ
What is the maximum input voltage rating for the NCV612SQ30T1G?
The NCV612SQ30T1G has a maximum input voltage rating of 6.0 V, as specified in its Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. It is designed to operate with inputs from 3.3 V (to maintain 3.0 V output with 230 mV dropout margin) up to 6.0 V, making it suitable for automotive 5 V rails and transient-tolerant applications.
Does the NCV612SQ30T1G require external compensation components?
No, the NCV612SQ30T1G is internally compensated and stable with 1.0 µF ceramic output capacitors - no external resistors, capacitors, or ESR tuning are needed. This simplifies layout and improves reliability compared to older LDOs requiring minimum ESR or external compensation networks.
Is the NCV612SQ30T1G pin-compatible with other devices in the NCV612 family?
Yes, all NCV612 variants - including NCV612SQ15T1G, NCV612SQ18T1G, and NCV612SQ33T1G - share identical SC70-5 pinout and electrical behavior except for output voltage. Pin 1 is Vin, Pin 2 is Gnd, Pin 3 is Enable, Pin 4 is N/C, and Pin 5 is Vout - enabling voltage-scaling flexibility without PCB redesign.
What is the output voltage accuracy of the NCV612SQ30T1G over temperature?
The NCV612SQ30T1G maintains output voltage within ±2.0% over its full operating range of −40 °C to +125 °C at 10 mA load, per the Electrical Characteristics table. At 100 mA and across temperature, deviation remains within ±3.0%, ensuring reliable power delivery to automotive microcontrollers and sensors.
How does the enable function behave when left unconnected on the NCV612SQ30T1G?
The enable pin of the NCV612SQ30T1G must not be left floating. If unused, it must be tied directly to Vin to ensure proper regulator activation. Leaving it open may cause erratic startup, oscillation, or failure to regulate - as confirmed by the Pin Function Description section stating "If this function is not used, Enable should be connected to Vin."
