The NCV8161BMX330TBG from onsemi is a high-performance, fixed 3.3V linear regulator designed for automotive and industrial applications. It delivers up to 450mA of output current with a low dropout voltage of 0.26V. The device features a quiescent current of 23 µA and exceptional power supply rejection ratio (91dB at 100Hz to 48dB at 100kHz), making it ideal for noise-sensitive environments. Packaged in a compact 4-XDFN (1x1mm), it is AEC-Q100 qualified for automotive reliability.
- Automotive Qualified: AEC-Q100 certified, ensuring reliable operation in harsh automotive environments.
- Superior Noise Rejection: High PSRR (91dB at 100Hz) filters out low-frequency noise from vehicle electrical systems.
- Low Dropout Voltage: 0.26V dropout at 450mA maintains output stability during battery voltage fluctuations.
- Compact Footprint: The 4-XDFN (1x1mm) package saves valuable board space in space-constrained modules.
Automotive Camera Modules
In automotive surround-view cameras, the NCV8161BMX330TBG provides a stable 3.3V supply for image sensors. Its high PSRR (91dB at 100Hz) rejects alternator noise, ensuring clear image capture.
Infotainment and Telematics
For car infotainment systems, this LDO powers microcontrollers and interface ICs. The low dropout of 0.26V ensures stable operation even during cranking conditions when battery voltage dips.
Advanced Driver Assistance Systems (ADAS)
ADAS sensors like radar and LiDAR require clean, stable power. The NCV8161's excellent PSRR across a wide frequency range (91dB to 48dB from 100Hz to 100kHz) filters out noise from switching converters in the vehicle.
Portable Automotive Diagnostics
Handheld diagnostic tools benefit from the 450mA output and low quiescent current, allowing them to run efficiently from vehicle power or internal batteries.
Industrial Sensor Interfaces
In industrial settings, this regulator can power 3.3V sensors and fieldbus interfaces. Its high PSRR helps maintain signal integrity in electrically noisy factory environments.
5G and RF Modules
For RF transceivers and 5G modules, a low-noise 3.3V supply is essential. The NCV8161's high PSRR at higher frequencies (48dB at 100kHz) makes it suitable for suppressing high-frequency noise.
