onsemi Low Dropout Voltage Regulator 5.5V 700mA WLCSP 4-Pin NCP167AFCT330T2G

onsemi NCP167AFCT330T2G is a low dropout (LDO) voltage regulator designed to supply a stable 5.5V output with up to 700 mA output current. Its architecture meets the performance requirements of RF and analog circuits by providing exceptionally low noise, high power supply rejection ratio (PSRR), and low quiescent current.

This voltage regulator supports an operating input voltage range from 1.9V to 5.5V and maintains very low dropout voltage of only 210 mV at 700 mA load, making it ideal for battery-powered and noise-sensitive applications.

The device is packaged in an ultra-small WLCSP 4-pin package measuring 0.65 mm by 0.65 mm with a height of 250 μm, facilitating compact PCB designs and space-constrained implementations. It is engineered to work efficiently with ceramic input and output capacitors of 1 μF.

Key electrical features include ultra-high PSRR of 85 dB at 1 kHz and ultra-low output noise of 8.5 μVRMS, ensuring minimal interference in sensitive circuits. The quiescent current is very low at 12 μA, optimizing battery life for portable electronic devices.

This voltage regulator is highly suitable for powering RF modules, camera modules, audio codec systems, and analog-to-digital or digital-to-analog converters, where noise and power efficiency are critical. It operates reliably up to a maximum temperature of 150°C, making it suitable for harsh industrial and consumer environments.

Offers ultra high PSRR up to 85dB at 1 kHz for excellent noise suppression. Features ultra low output noise of 8.5 μVRMS ensuring stable voltage output. Operates within an input voltage range of 1.9V to 5.5V for versatile power conditions.

Designed with low quiescent current of 12 μA for energy-efficient battery-powered devices. Available in compact WLCSP 4-pin package measuring 0.65 mm x 0.65 mm by 250 μm height. Excellent for applications including RF modules, camera modules, audio codecs, and A/D & D/A converters.

Maximum operating temperature is rated at 150°C enabling use in demanding environments. Supports low power dissipation at full load for extended device reliability.

This product is widely used in industrial, consumer electronics, telecommunications, and automotive sectors requiring precise voltage regulation with minimal noise interference. The ultra-compact package is ideal for space-constrained assemblies, while its robust electrical characteristics support high-performance embedded system designs.
