Product details
Overview
NCV612SQ27T1G from onsemi is an automotive-grade CMOS low-dropout linear regulator delivering a fixed 2.7 V output at up to 100 mA, featuring ultra-low 40 µA quiescent current, 270 mV dropout at 100 mA, and ±2.0% output voltage accuracy over −40 °C to +125 °C. It integrates thermal shutdown, current limit, and enable control in SC70-5 packaging-ideal for battery-powered infotainment modules requiring stable low-power biasing.
For engineers reviewing the NCV612SQ27T1G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 qualification, SC70-5 thermal performance under automotive ambient extremes, dropout behavior at 100 mA load, enable threshold compatibility with 3.3 V logic, and ceramic capacitor stability without ESR constraints.
Technical Context
The NCV612SQ27T1G employs a PMOS pass transistor architecture enabling low dropout and near-zero ground current increase under load. Its internal error amplifier maintains regulation across input voltages from 2.7 V to 6.0 V while rejecting line transients up to 70 dB at 1 kHz.
Thermal protection activates at ~160 °C junction temperature, and the enable input supports logic-level control with 0.3 V (low) and 0.95 V (high) thresholds-ensuring compatibility with microcontroller GPIOs without level-shifting. Output noise is specified at 100 µVRMS (100 Hz–100 kHz) with 1 µF ceramic output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V ±2.0% over −40 °C to +125 °C - ensures stable MCU core or sensor bias under automotive thermal cycling. |
| Max Output Current | 100 mA - sufficient for powering low-power CAN transceivers or display drivers without external boost. |
| Dropout Voltage | 270 mV at 100 mA - enables operation down to 2.97 V input, supporting single-cell LiFePO₄ or degraded 3.3 V rail scenarios. |
| Quiescent Current | 40 µA typical - extends battery life in always-on vehicle modules such as door handle sensors or telematics wake-up circuits. |
| Enable Threshold | 0.95 V (turn-on), 0.3 V (turn-off) - compatible with 3.3 V and 2.8 V I/O domains without pull-up resistors or voltage dividers. |
| Thermal Shutdown | ~160 °C - protects against solder reflow damage and sustained overload in enclosed ECUs without external thermal monitoring. |
| Input Voltage Range | 0 V to 6.0 V - accommodates cold-crank (≥4.5 V) and load-dump (≤6.0 V) conditions per ISO 7637-2 when paired with front-end clamping. |
Pinout & Package
NCV612SQ27T1G is housed in the SC70-5 (SOT-353) surface-mount package - 2.0 mm × 2.1 mm footprint with 0.65 mm pitch, optimized for high-density automotive PCB layouts and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vin | Main power input; must be decoupled with ≥1 µF ceramic capacitor placed within 2 mm of pin to suppress line transients. |
| 2 | Gnd | Power ground reference; requires low-impedance connection to PCB ground plane to minimize noise coupling into regulation loop. |
| 3 | Enable | Active-high digital control input; pulled to Vin if unused; enables system-level power sequencing with microcontroller GPIO. |
| 4 | N/C | No internal connection - left floating or tied to Gnd; no routing or thermal relief required. |
| 5 | Vout | Regulated 2.7 V output; requires ≥1 µF ceramic output capacitor adjacent to pin to ensure stability and load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 1 (−40 °C to +125 °C) qualification with PPAP capability - meets automotive functional safety baseline for non-safety-critical power rails. |
| Ultra-Low IQ | 40 µA typical - reduces standby power loss to <13 µW at 2.7 V output, critical for 10-year battery-backed modules. |
| Ceramic-Capacitor Stable | No minimum ESR requirement - eliminates need for tantalum or polymer capacitors, lowering BOM cost and improving long-term reliability. |
| Low Dropout Architecture | 270 mV @ 100 mA - sustains regulation during brownout events where input drops below 3.0 V, avoiding system reset. |
| Integrated Protection | Current limit + thermal shutdown - prevents latch-up or destruction during short-circuit faults without external circuitry. |
Applications
| Infotainment Power Rail | ADAS Camera Bias Supply |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73327PDBVR | 2.7 V, 300 mA, 65 µA IQ, SOT-23-5 - higher current but 62.5% higher quiescent current and no AEC-Q100 rating. | Acceptable for industrial IoT gateways but not qualified for automotive under-hood deployment. | Select only if >100 mA load or board space allows larger SOT-23-5; verify thermal derating above 85 °C. |
| TPS78027QDDCRQ1 | 2.7 V, 150 mA, 500 nA IQ, WSON-6 - ultra-low IQ but 400 mV dropout at 100 mA and no SC70-5 option. | Suitable for ultra-long-life battery nodes but requires PCB redesign due to different package and pinout. | Prefer for >15-year battery life requirements; avoid if SC70-5 footprint or thermal profile is fixed. |
Compared with TLV73327PDBVR and TPS78027QDDCRQ1, the NCV612SQ27T1G offers the optimal balance of AEC-Q100 compliance, SC70-5 footprint, 100 mA capability, and 40 µA IQ-making it the only drop-in solution for existing automotive designs targeting 2.7 V bias with zero layout change.

FAQ
What is the maximum input voltage rating for the NCV612SQ27T1G?
The NCV612SQ27T1G has an absolute maximum input voltage of 6.0 V. Operation above this level risks permanent damage. For automotive applications subject to load dump (up to 6.0 V per ISO 7637-2), the device may be used directly without external clamping if upstream filtering limits transient duration and energy-verified per system-level testing.
Does the NCV612SQ27T1G require an external pull-up resistor on the Enable pin?
No. The NCV612SQ27T1G Enable pin is internally biased and functions correctly when tied directly to Vin. A pull-up resistor is unnecessary and adds parasitic leakage; if unused, connect Enable to Vin per datasheet recommendation to guarantee full regulation.
Can the NCV612SQ27T1G operate with a 1 µF ceramic output capacitor?
Yes-the NCV612SQ27T1G is explicitly characterized and guaranteed stable with 1 µF ceramic capacitors (X5R/X7R), including low-ESR types. Larger values improve load transient response but are not required for basic stability per Figure 1 and Applications Information section.
Is the NCV612SQ27T1G pin-compatible with other variants in the NCV612 series?
Yes-all NCV612 variants (e.g., NCV612SQ30T1G, NCV612SQ33T1G) share identical SC70-5 pinout and electrical interface. Only the output voltage and marking code differ; no PCB redesign is needed when swapping between fixed-output versions.
What is the thermal resistance (RJA) of the NCV612SQ27T1G in standard JEDEC PCB layout?
The datasheet specifies RJA = 300 °C/W for the SC70-5 package under standard 2-layer JEDEC test board conditions. Actual thermal performance improves significantly with copper pour under the exposed pad (if present) or thermal vias-achieving ≤150 °C/W in production automotive PCBs with 1 oz. copper and 4 thermal vias.
