Product details
Overview
NCV33375D-2.5R2G from onsemi is an automotive-grade, low-dropout linear voltage regulator delivering a fixed 2.5 V output at up to 300 mA, featuring logic-level ON/OFF control, 2% output voltage tolerance over −40 °C to +125 °C, 260 mV dropout at full load, and AEC-Q100 qualification for under-hood and safety-critical power rails in vehicle ECUs and ADAS sensors.
For engineers reviewing the NCV33375D-2.5R2G datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8, Case 751), confirmed thermal shutdown at 150 °C, validated quiescent current of 125 µA in ON mode and 0.3 µA in OFF mode, and real-world stability with only 0.33 µF output capacitance.
Technical Context
The NCV33375D-2.5R2G integrates a PNP pass transistor with internal current limiting (450 mA typical) and thermal shutdown (150 °C junction threshold), enabling robust operation without external protection circuitry. Its control pin accepts TTL/CMOS-compatible logic levels (VCTRL ≥ 2.4 V for ON, ≤ 0.5 V for OFF) and requires no pull-up resistor when driven actively.
Designed for battery-powered systems, it achieves ultra-low quiescent current (125 µA ON / 0.3 µA OFF) and tight line regulation (2.0 mV typical) and load regulation (5.0 mV typical), supporting stable 2.5 V rail generation even with input voltages as low as 2.75 V (2.5 V + 250 mV dropout).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.50 V ±2% over −40 °C to +125 °C - ensures reliable logic-level supply for automotive microcontrollers and analog sensors. |
| Max Output Current | 300 mA - sufficient to power multiple CAN transceivers or small MCU subsystems without derating. |
| Dropout Voltage | 260 mV at 300 mA - enables operation from weak or aging 3.3 V or 5 V supplies with minimal headroom loss. |
| Quiescent Current | 125 µA (ON), 0.3 µA (OFF) - extends battery life in always-on vehicle modules like telematics and door controllers. |
| Thermal Shutdown | 150 °C junction temperature - protects against sustained overload or poor PCB heatsinking in enclosed enclosures. |
| Ripple Rejection | 65 dB at 120 Hz - suppresses alternator ripple and switching noise from upstream DC/DC converters. |
| Stability Capacitance | 0.33 µF ceramic - allows compact, low-BOM-count designs without tantalum or large electrolytic capacitors. |
Pinout & Package
NCV33375D-2.5R2G uses the SOIC-8 (Case 751) surface-mount package, with exposed pad for enhanced thermal performance. Pin 1 is located at the top-left corner adjacent to the index notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (Vin) | Main power input; must be decoupled with ≥0.33 µF capacitor near pin to ensure stability and transient response. |
| 2 | GND | Analog ground reference; connects to system ground plane with low-inductance path to minimize noise coupling. |
| 3 | ON/OFF | Active-low enable control; pulled high internally; must be driven to ≤0.5 V to disable regulator output. |
| 4 | GND | Second ground terminal; tied to same ground net as Pin 2 to reduce ground loop impedance and improve PSRR. |
| 5 | GND | Third ground terminal; used for thermal conduction and low-impedance return path in high-current layouts. |
| 6 | GND | Fourth ground terminal; enhances thermal dissipation and reduces output voltage error under dynamic load. |
| 7 | Vout | Regulated 2.5 V output; requires 0.33 µF ceramic capacitor placed within 2 mm for guaranteed stability. |
| 8 | NC | No connect; left unconnected per datasheet - not internally bonded and must not be tied to any signal or plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified (Grade 1) | Validated for −40 °C to +125 °C ambient operation - meets automotive reliability requirements for engine control and body electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8664CDT25RKG | 2.5 V fixed output, 500 mA rating, 300 mV dropout at 500 mA, higher IQ (250 µA ON), SOIC-8 package | Higher current capability suits dual-rail sensor hubs; less suitable for ultra-low-power sleep modes due to higher OFF current (1 µA) | Select when >300 mA load margin or higher thermal robustness is required; verify layout compatibility with larger die size. |

FAQ
What is the maximum input voltage rating for NCV33375D-2.5R2G?
The NCV33375D-2.5R2G has an absolute maximum input voltage of 13 Vdc. Operation above this level risks permanent damage. For reliable 2.5 V output regulation, the recommended input range is 2.75 V to 12 V, ensuring sufficient headroom across temperature and load conditions while staying within safe operating limits.
Does NCV33375D-2.5R2G require an external pull-up resistor on the ON/OFF pin?
No, the NCV33375D-2.5R2G does not require an external pull-up resistor on the ON/OFF pin. The device includes an internal pull-up that holds the regulator enabled by default. To disable the output, drive the pin to ≤0.5 V using a microcontroller GPIO or open-collector driver - leaving it floating is not permitted per datasheet guidance.
Can NCV33375D-2.5R2G operate with a 0.22 µF output capacitor?
No - the NCV33375D-2.5R2G requires a minimum of 0.33 µF ceramic output capacitance for guaranteed stability at 2.5 V output. While 0.22 µF may suffice for 5.0 V versions per datasheet, using it with NCV33375D-2.5R2G risks oscillation or poor transient response. Always use ≥0.33 µF placed within 2 mm of pins 7 (Vout) and 2/4/5/6 (GND).
Is NCV33375D-2.5R2G pin-compatible with MC33375D-2.5R2G?
Yes - NCV33375D-2.5R2G and MC33375D-2.5R2G share identical SOIC-8 (Case 751) pinout, electrical specifications, and functional behavior. The NCV prefix denotes automotive qualification (AEC-Q100 Grade 1, PPAP-capable), while the MC version is for commercial/industrial use. No PCB changes are needed when upgrading from MC to NCV for automotive programs.
What is the thermal resistance (RJA) of NCV33375D-2.5R2G in standard SOIC-8 layout?
In a standard SOIC-8 layout with minimal copper (no thermal pad connection), the NCV33375D-2.5R2G exhibits a junction-to-ambient thermal resistance (RJA) of 160 °C/W. With a 100 mm² 2-oz copper pour connected to the exposed pad (pins 2/4/5/6), RJA improves to ~60 °C/W - critical for sustaining 300 mA output at high ambient temperatures without thermal shutdown.
