onsemi Linear Voltage Regulator 5.5V 450mA Low Noise Low Quiescent Current TSOP-5 NCV8161BSN330T1G

The onsemi NCV8161BSN330T1G is a high-performance linear voltage regulator designed to supply up to 450mA output current in a compact TSOP-5 package. Operating with a maximum input voltage of 5.5V and a minimum input voltage of 1.9V, this regulator provides excellent supply noise rejection and very low output noise, making it ideal for sensitive RF and analog electronics applications.

Thanks to its very low dropout voltage of 225mV at full load current and ultra-low quiescent current of 18µA, the NCV8161BSN330T1G achieves high efficiency, especially during light load conditions. It operates reliably over a wide temperature range with a maximum operating temperature of 125°C, meeting the stringent automotive-grade AEC-Q100 standard.

This device's compact surface mount TSOP-5 package (3.15mm x 1.65mm x 1mm) is well suited for space-constrained designs. It requires only a 1µF ceramic capacitor on both input and output for stable operation, simplifying PCB layout and reducing component count.

Common industrial and automotive applications include use in automotive infotainment systems, parking camera modules, intelligent rearview mirrors, audio codecs, and precision analog circuits. Its ultra-high PSRR (90dB at 1kHz) and low noise features ensure stable power delivery to sensitive circuit blocks in these applications.

Provides a stable 450mA output current suitable for RF and analog circuit applications. Features an ultra-high power supply rejection ratio (PSRR) of 90dB at 1kHz and 20mA load. Delivers ultra-low output noise of 10µVRMS, ideal for noise-sensitive devices such as camera modules.

Designed with a very low dropout voltage of 225mV at 450mA output current. Operates with ultra-low quiescent current of 18µA to improve efficiency under light load conditions. Complies with automotive standard AEC-Q100, ensuring reliability under harsh automotive environments.
