onsemi Voltage Regulator 5.5V SOT-23 5-Pin NCP161ASN280T1G

onsemi NCP161ASN280T1G is a highly efficient voltage regulator designed in a compact SOT-23 5-pin surface mount package. It supports an operating input voltage range from 1.9V to 5.5V, delivering stable regulated output suitable for power sensitive and noise sensitive electronic devices.

This voltage regulator features ultra high power supply rejection ratio (PSRR) of 98dB at 1kHz and 48dB at 100kHz, allowing it to maintain low noise output even in electrically noisy environments. The ultra low quiescent current of 23μA adds to its efficiency, making it ideal for battery-powered applications such as Wi-Fi modules, camera modules, and portable electronics.

With a very low dropout voltage of 150mV at 450mA, the device ensures operational efficiency during light load conditions and helps extend battery life. The low output noise of 10 μVRMS is advantageous for precision analog circuits, audio codecs, and RF modules.

The device is rated for maximum operating temperatures up to 150°C, making it suitable for harsh industrial applications. Its positive polarity and surface mount SOT-23 package with dimensions of 670μm length, 670μm width, and 230μm height allow for easy integration in space-constrained PCB layouts.

Applications span a wide range including A/D and D/A converters, battery-powered equipment, smartphones, tablets, wireless routers, cameras, and camcorders. Its design ensures low power dissipation at full load, making it a reliable choice for efficient power management in electronic products.
