Product details
Overview
NCV612SQ27T2G from onsemi is an automotive-grade, fixed-output CMOS low-dropout linear regulator delivering 2.7 V at up to 100 mA with 40 µA typical quiescent current, 230 mV dropout at 100 mA, ±2.0% output voltage accuracy, and operation across −40 °C to +125 °C - designed for battery-powered infotainment modules and ADAS sensor power rails.
For engineers reviewing the NCV612SQ27T2G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC-Q100 qualification, SC70-5 thermal performance under load transients, ultra-low IQ in sleep mode, and compatibility with 1.0 µF ceramic output capacitors without ESR constraints.
Technical Context
The NCV612SQ27T2G integrates a PMOS pass transistor, precision voltage reference, error amplifier, and thermal/current-limit protection - enabling stable regulation with minimal external components. Its enable-controlled shutdown reduces system standby current to <0.03 µA, while internal compensation ensures stability with 1.0 µF ceramic output capacitance.
Designed for automotive environments, it features −40 °C to +125 °C operating ambient range, 100 ppm/°C output voltage temperature coefficient, and ripple rejection >50 dB at 1 kHz (IOUT = 80 mA), supporting noise-sensitive analog and RF subsystems powered from noisy 5 V or 12 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V ±2.0% over −40 °C to +125 °C - ensures consistent biasing for 2.7 V logic or analog sensors. |
| Max Output Current | 100 mA continuous - sufficient for powering microcontrollers, CAN transceivers, or camera ISPs. |
| Quiescent Current | 40 µA typical at 10 mA load - enables multi-year battery life in always-on vehicle modules. |
| Dropout Voltage | 230 mV at 100 mA - allows regulation from 3.0 V input when main rail sags during cold-crank. |
| Thermal Range | −40 °C to +125 °C ambient - meets AEC-Q100 Grade 1 requirements for under-hood placement. |
| Ripple Rejection | ≥50 dB at 1 kHz - suppresses switching noise from DC-DC converters feeding the LDO input. |
| Enable Threshold | VEN(H) = 0.95 V min, VEN(L) = 0.3 V max - compatible with 1.8 V/3.3 V GPIO control without level-shifting. |
Pinout & Package
Housed in SC70-5 (Case 419A) - a 1.25 mm × 1.65 mm × 0.95 mm surface-mount package with 0.65 mm lead pitch, optimized for high-density automotive PCBs and thermally constrained layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vin | Input supply connection - accepts 2.7 V to 6.0 V; requires local 1.0 µF ceramic decoupling. |
| 2 | Gnd | Power ground reference - must be low-impedance path to minimize noise coupling and thermal rise. |
| 3 | Enable | Active-high digital control - pulls low to disable regulator and reduce IQ to <0.03 µA; tie to Vin if unused. |
| 4 | N/C | No internal connection - left floating; no routing or soldering required. |
| 5 | Vout | Regulated 2.7 V output - supports 1.0 µF ceramic capacitor; ESR-insensitive for layout flexibility. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Qualified | Grade 1 (−40 °C to +125 °C) - certified for automotive power management in safety-critical ECUs. |
| Ultra-Low Quiescent Current | 40 µA typical - extends battery runtime in telematics and remote keyless entry systems. |
| Low Dropout Architecture | 230 mV @ 100 mA - maintains regulation during engine cranking when input drops to 3.0 V. |
| Ceramic Capacitor Compatible | Stable with 1.0 µF X5R/X7R MLCC - eliminates need for tantalum, reducing BOM cost and failure risk. |
| Integrated Protection | Thermal shutdown (160 °C) and current limit (150–600 mA) - prevents latch-up during short-circuit events. |
Applications
| Infotainment Power Rail | ADAS Camera Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8170DS270TCG | 2.7 V, 150 mA, 25 µA IQ, SOT-563 - lower quiescent current but larger footprint and no enable pin. | Suitable for space-tolerant modules where enable control is unnecessary and 150 mA headroom is required. | Select when lowest possible IQ dominates over footprint and control flexibility. |
| TLV73327PDBVR | 2.7 V, 300 mA, 35 µA IQ, SOT-23-5 - higher current, wider input range (1.4–5.5 V), but not AEC-Q100 qualified. | Applicable in industrial or consumer designs needing higher output current without automotive certification. | Select for non-automotive applications requiring >100 mA or tighter input voltage range. |
Compared with NCV612SQ27T2G, NCV8170DS270TCG offers lower IQ but sacrifices enable functionality and automotive qualification, while TLV73327PDBVR provides greater current headroom and smaller dropout at low loads but lacks AEC-Q100 validation - making NCV612SQ27T2G the only option meeting full automotive reliability and control requirements in its class.

FAQ
What is the maximum input voltage rating for the NCV612SQ27T2G?
The NCV612SQ27T2G supports an absolute maximum input voltage of 6.0 V. Exceeding this value risks permanent damage per the Absolute Maximum Ratings table. For reliable operation, maintain Vin ≤ Vout + 3.3 V (i.e., ≤ 6.0 V for 2.7 V output) and ensure transient spikes remain within specification limits using appropriate input filtering.
Does the NCV612SQ27T2G require an external resistor network to set output voltage?
No, the NCV612SQ27T2G is a fixed-output regulator with internally trimmed 2.7 V reference. It contains integrated feedback resistors and requires no external components to configure Vout - simplifying design and improving accuracy versus adjustable LDOs with external resistor tolerances.
Is the NCV612SQ27T2G pin-compatible with other variants in the NCV612 family?
Yes, all NCV612 variants including NCV612SQ15T2G, NCV612SQ25T2G, NCV612SQ27T2G, and NCV612SQ33T2G share identical SC70-5 pinout and electrical interface - enabling drop-in replacement across output voltages without PCB revision.
What is the thermal shutdown threshold of the NCV612SQ27T2G?
The NCV612SQ27T2G activates internal thermal protection at approximately 160 °C junction temperature. Once triggered, the device disables output until junction temperature falls below the hysteresis threshold (~140 °C), preventing sustained overheating during overload or poor heatsinking conditions.
Can the NCV612SQ27T2G operate with a 1.0 µF ceramic capacitor on the output?
Yes, the NCV612SQ27T2G is explicitly characterized and stabilized for use with 1.0 µF ceramic capacitors (X5R/X7R dielectrics). Unlike many LDOs, it imposes no minimum ESR requirement, eliminating the need for bulkier tantalum or aluminum electrolytic capacitors in space-constrained automotive layouts.
